1
00:00:00,000 --> 00:00:00,870
Hi, everyone.
2
00:00:00,880 --> 00:00:02,790
Welcome to be on space, even at the tundra.
3
00:00:03,060 --> 00:00:06,750
In today's episode, we'll talk about a very interesting star
4
00:00:06,780 --> 00:00:15,600
nearby known as Captain Set, which is similar to our sun
5
00:00:15,690 --> 00:00:17,460
in it was young.
6
00:00:18,000 --> 00:00:22,890
And our next guest is Universal Physicist at the NASA Got
7
00:00:23,070 --> 00:00:27,810
Space by Senator has deleted the author of the recent paper
8
00:00:28,920 --> 00:00:30,540
regarding the star.
9
00:00:30,750 --> 00:00:32,910
So without any further Ado, please welcome.
10
00:00:33,240 --> 00:00:35,970
Please welcome Vladimir Aircam.
11
00:00:35,980 --> 00:00:36,540
Hi, Value.
12
00:00:37,680 --> 00:00:38,680
Hello.
13
00:00:38,690 --> 00:00:40,030
Thank you for inviting me.
14
00:00:40,040 --> 00:00:42,040
It's great to have you here.
15
00:00:42,050 --> 00:00:42,400
Okay.
16
00:00:42,900 --> 00:00:49,480
So the first question to get a better general view of your
17
00:00:49,490 --> 00:00:52,600
study, what exactly is the capital one city?
18
00:00:52,610 --> 00:00:53,920
What do we know about the star?
19
00:00:55,030 --> 00:00:56,030
Yeah.
20
00:00:56,270 --> 00:01:03,020
So the couple of city is one of a number of stars that astronomers
21
00:01:03,030 --> 00:01:08,950
started to monitor about 25 years ago, 30 years ago.
22
00:01:08,960 --> 00:01:10,000
Yeah.
23
00:01:10,010 --> 00:01:14,770
Because we're trying to understand our sun in its youth.
24
00:01:15,250 --> 00:01:20,800
And for that, we have a number of indicators that tell us
25
00:01:20,810 --> 00:01:26,680
about its use, the stellar youth, the stellar age, and, for
26
00:01:26,690 --> 00:01:31,210
instance, stellar rotation, how fast the stars rotate.
27
00:01:31,240 --> 00:01:35,050
For instance, the average rotation rate of our sons, like
28
00:01:35,060 --> 00:01:36,640
once every 27 days.
29
00:01:36,970 --> 00:01:39,880
And for instance, and what does it mean that if a star rotates
30
00:01:39,890 --> 00:01:43,300
once every three days, every five days, every ten days?
31
00:01:43,930 --> 00:01:47,500
And the astronomy is actually beautiful science, because
32
00:01:47,510 --> 00:01:51,100
we can go out on a clear night practically every day, if
33
00:01:51,110 --> 00:01:52,300
you're in a right place.
34
00:01:52,360 --> 00:01:52,600
Right.
35
00:01:52,600 --> 00:01:54,040
And observe the stars.
36
00:01:54,430 --> 00:01:58,240
And believe it or not, about, like, 10% of all stars that
37
00:01:58,250 --> 00:02:00,790
in our Galaxy are stars like our sun.
38
00:02:01,030 --> 00:02:03,610
So we have a lot of material to work with.
39
00:02:04,000 --> 00:02:07,630
And if we're smart, we can find this subset of stars that
40
00:02:07,780 --> 00:02:08,919
resemble our son.
41
00:02:11,220 --> 00:02:12,970
It's current age.
42
00:02:13,330 --> 00:02:15,610
So we have a lot of them, by the way.
43
00:02:15,620 --> 00:02:19,290
But by itself, it's a very important a question because we
44
00:02:19,300 --> 00:02:21,420
don't know how typical our son is.
45
00:02:21,630 --> 00:02:29,010
For instance, if you want to find a typical 50 year old male
46
00:02:29,280 --> 00:02:34,470
in the United States or in China, and what would you do?
47
00:02:34,480 --> 00:02:37,620
You would study, create example, right.
48
00:02:37,890 --> 00:02:39,540
And then do statistics.
49
00:02:39,870 --> 00:02:41,220
So that's exactly what we do.
50
00:02:41,790 --> 00:02:48,060
And for that, we know a few important parameters of stars.
51
00:02:48,390 --> 00:02:52,470
So basically, this kind of approach was taken in order to
52
00:02:52,500 --> 00:02:58,470
study and reveal a subset of stars.
53
00:02:58,530 --> 00:03:05,100
And a coup one city is one of them that is rotating at a
54
00:03:05,130 --> 00:03:09,180
rate of nine two days rotation, which is like three times
55
00:03:09,210 --> 00:03:10,770
faster than our sun.
56
00:03:10,780 --> 00:03:14,460
And now we know that the fastest star rotates the younger
57
00:03:14,470 --> 00:03:16,350
it is, so we can calibrate the age.
58
00:03:16,500 --> 00:03:20,100
So that's how we know that the star is about 600, 700 million
59
00:03:20,110 --> 00:03:20,640
years old.
60
00:03:20,820 --> 00:03:27,790
And that coincides with the start of life origin of life
61
00:03:27,800 --> 00:03:28,300
on Earth.
62
00:03:28,310 --> 00:03:31,030
So it's basically a life started for billion years ago.
63
00:03:31,040 --> 00:03:36,430
So that's why I got my interest in that star, because I thought,
64
00:03:36,440 --> 00:03:39,340
well, life started for billion years ago.
65
00:03:39,400 --> 00:03:44,410
People normally talk about different factors that are affecting
66
00:03:44,410 --> 00:03:47,710
the origin of life on Earth, and they're almost Geophysical
67
00:03:48,160 --> 00:03:50,410
related to the Earth.
68
00:03:50,590 --> 00:03:53,380
But no one talks about the they're basically more global
69
00:03:53,390 --> 00:03:57,310
parameters. And this kind of question that was naive and
70
00:03:57,320 --> 00:04:01,000
sometimes crazy, whether our sun can actually somehow affect
71
00:04:01,240 --> 00:04:02,860
the origin of life on Earth.
72
00:04:03,330 --> 00:04:05,200
It is true or not.
73
00:04:05,210 --> 00:04:07,900
I mean, at least we need to start this scientific study to
74
00:04:08,380 --> 00:04:09,220
answer the question.
75
00:04:09,340 --> 00:04:11,860
So that's basically about, like, five, six years ago, when
76
00:04:11,870 --> 00:04:16,510
I asked myself this question, I started to look at the stars,
77
00:04:16,519 --> 00:04:19,209
and the couple one side was one of them.
78
00:04:19,220 --> 00:04:20,860
It's not the only star.
79
00:04:20,870 --> 00:04:25,180
So currently I'm doing the Hubble Fast Scope and XMM study
80
00:04:25,360 --> 00:04:28,240
of four stars, and they're all pretty similar.
81
00:04:28,420 --> 00:04:30,760
Now I want to know which one is the best one.
82
00:04:31,090 --> 00:04:33,760
Well, it's like saying that which one is the best person
83
00:04:34,000 --> 00:04:35,080
on this planet.
84
00:04:35,440 --> 00:04:37,480
Well, we need to say that relevant.
85
00:04:37,510 --> 00:04:37,780
Right.
86
00:04:37,790 --> 00:04:39,790
Muslim, and it looks like relevant.
87
00:04:39,880 --> 00:04:40,390
Yeah.
88
00:04:40,400 --> 00:04:45,730
But this one is nearby for the years away.
89
00:04:45,760 --> 00:04:46,960
It's not so distant.
90
00:04:46,970 --> 00:04:47,230
Right.
91
00:04:47,260 --> 00:04:53,850
And we have the kind of solar analog in our neighborhood.
92
00:04:54,700 --> 00:04:55,690
Yeah.
93
00:04:55,690 --> 00:04:57,700
Well, actually, yes, you are absolutely correct.
94
00:04:57,710 --> 00:05:00,760
It is very nearby star.
95
00:05:01,150 --> 00:05:02,620
And that's why it's pretty bright.
96
00:05:03,520 --> 00:05:08,260
And because it's so bright, it can be absorbed with pretty
97
00:05:08,270 --> 00:05:11,890
small telescopes and study in more details than others.
98
00:05:12,280 --> 00:05:15,960
And so that's that's why a lot of efforts were taken.
99
00:05:16,500 --> 00:05:21,870
And still people observe the star a monitor, because it's
100
00:05:21,880 --> 00:05:26,310
like if you look at a person again, I like to compare people
101
00:05:26,640 --> 00:05:30,390
the human life with the stellar life, because when you look
102
00:05:30,400 --> 00:05:37,740
at a person just at one time moment, you can find it angry
103
00:05:38,130 --> 00:05:41,670
or extremely quiet or in the state of depression.
104
00:05:41,700 --> 00:05:42,060
Right.
105
00:05:42,060 --> 00:05:44,910
So it's the same thing happen to the star.
106
00:05:44,920 --> 00:05:48,720
So we need to know what is the typical state of the star
107
00:05:48,720 --> 00:05:50,550
is that called background level.
108
00:05:51,150 --> 00:05:56,670
And then sometimes those stars flare, they eject a lot of
109
00:05:56,680 --> 00:05:58,680
energy out of it called self flares.
110
00:05:59,020 --> 00:06:02,950
So we need to know how frequently what is going on.
111
00:06:03,610 --> 00:06:04,610
Okay.
112
00:06:04,670 --> 00:06:08,240
So if we can go through the findings from your research,
113
00:06:08,250 --> 00:06:10,160
what exactly did you find?
114
00:06:10,170 --> 00:06:11,540
What are the main results?
115
00:06:12,540 --> 00:06:13,540
Yeah.
116
00:06:13,780 --> 00:06:20,050
So the study of the young stars like a young son, I call
117
00:06:20,050 --> 00:06:26,230
it is going on for maybe 1015 years.
118
00:06:26,460 --> 00:06:30,060
People already started to look at it.
119
00:06:30,070 --> 00:06:35,280
And I published the paper back to 2016.
120
00:06:35,960 --> 00:06:39,900
Basically, studying starts, like, up one city doing the three
121
00:06:40,280 --> 00:06:41,700
national modeling.
122
00:06:41,710 --> 00:06:51,180
The point is that so now we're fortunate that we have a sun
123
00:06:51,510 --> 00:06:52,910
nearby. Right.
124
00:06:52,920 --> 00:06:56,720
Our son, the star like, G type star, and it's only about
125
00:06:56,720 --> 00:06:59,690
93 million mile away from us.
126
00:07:00,050 --> 00:07:03,305
So we can resolve structures as small as about 3 miles, 25
127
00:07:03,321 --> 00:07:05,960
miles. All imagine, believe it or not.
128
00:07:05,970 --> 00:07:06,980
Yeah.
129
00:07:07,820 --> 00:07:19,230
And so by having so many detailed observations, we can apply
130
00:07:19,530 --> 00:07:23,700
and develop and apply sophisticated models, physics based,
131
00:07:23,710 --> 00:07:27,870
three dimensional, multi dimensional models, and then test
132
00:07:27,870 --> 00:07:31,530
them. Because, for instance, if we predict the stellar wind
133
00:07:31,540 --> 00:07:36,000
or predict certain signatures of a star, we can measure it,
134
00:07:36,030 --> 00:07:38,580
right? Because it's so close to us.
135
00:07:38,760 --> 00:07:41,850
The Earth is only at one aseremic unit away.
136
00:07:42,150 --> 00:07:45,720
We cannot do it for any star.
137
00:07:45,730 --> 00:07:49,860
But so we tested they calibrated those sophisticated models
138
00:07:49,870 --> 00:07:50,490
for our son.
139
00:07:50,700 --> 00:07:54,540
And the question that I ask myself, I said, okay, because
140
00:07:54,550 --> 00:07:58,620
I'm a Helio physicist, not only astrophysicist and astrobiologist.
141
00:07:58,760 --> 00:08:03,500
So the important thing for me and the sun is my favorite
142
00:08:03,560 --> 00:08:04,850
star, believe it or not.
143
00:08:05,500 --> 00:08:11,510
And I said, well, those models are pretty satisfactory.
144
00:08:11,510 --> 00:08:17,450
And to explain the most of the signature.
145
00:08:17,460 --> 00:08:20,480
So our sun at different epics.
146
00:08:20,490 --> 00:08:21,650
So can we apply that?
147
00:08:21,660 --> 00:08:22,430
What do I need?
148
00:08:22,440 --> 00:08:24,650
What kind of data do I need to input?
149
00:08:24,710 --> 00:08:28,430
And you would imagine that if you have a model model has
150
00:08:28,440 --> 00:08:32,390
an input and then produces output and the output.
151
00:08:32,450 --> 00:08:36,500
Is that something that you test, something that you you cannot
152
00:08:36,510 --> 00:08:40,309
measure and what we cannot measure for a couple on a let's
153
00:08:40,320 --> 00:08:47,240
say you cannot measure the stellar wind, which is the Chinese
154
00:08:47,250 --> 00:08:54,170
flow of particles outflow from the star called stellar wind.
155
00:08:54,320 --> 00:08:56,780
It cannot be so far observed directly.
156
00:08:57,530 --> 00:09:00,200
So therefore, we need to somehow predict because it's very,
157
00:09:00,210 --> 00:09:02,060
very important for our Earth.
158
00:09:02,440 --> 00:09:07,120
And then this extreme UV mission is also important for the
159
00:09:07,130 --> 00:09:10,180
Earth atmosphere, because there's the ionizing factor of
160
00:09:10,190 --> 00:09:11,980
the atmosphere and my belt.
161
00:09:11,990 --> 00:09:15,820
Ron, we can talk about exactly what I mean, but that can
162
00:09:15,830 --> 00:09:19,150
create detrimental conditions for us here on Earth.
163
00:09:19,380 --> 00:09:24,580
But if I cannot measure at only model right.
164
00:09:24,590 --> 00:09:28,030
But in order to model correctly, I need the right input.
165
00:09:28,360 --> 00:09:29,350
So that's the point.
166
00:09:29,890 --> 00:09:33,550
I started to think what kind of input solar physicist we
167
00:09:33,670 --> 00:09:36,370
basically use to characterize our sun.
168
00:09:36,490 --> 00:09:40,240
And I said, okay, so we need to make the observations of
169
00:09:40,250 --> 00:09:46,420
this specific spectral line of this finger points of lines
170
00:09:46,430 --> 00:09:50,320
forming that not very far from the surface of the sun and
171
00:09:50,330 --> 00:09:51,160
not very close.
172
00:09:51,340 --> 00:09:55,600
But at some level that characterizes that, we can specify
173
00:09:55,690 --> 00:10:01,360
the energy available that can propagate upward and create
174
00:10:01,600 --> 00:10:04,000
outermost layer Cal Corona.
175
00:10:04,220 --> 00:10:11,270
The Corona is the one important arena of all those interesting
176
00:10:11,930 --> 00:10:15,800
events. Explore events that occur in the life of our son
177
00:10:16,010 --> 00:10:17,660
and in the life for young sons.
178
00:10:17,670 --> 00:10:18,980
So called still flares.
179
00:10:19,070 --> 00:10:22,160
And we need to correctly characterize it before people are
180
00:10:22,170 --> 00:10:25,850
tasting. Okay, so let's assume that the Coron is already
181
00:10:25,860 --> 00:10:29,810
there. And let's get some parameters and then predict the
182
00:10:29,820 --> 00:10:32,660
sell win because telwin transitions from Corona out.
183
00:10:33,500 --> 00:10:37,070
So I asked my myself, and that's what I did also 2016.
184
00:10:37,080 --> 00:10:42,170
But in this study, my team asked a little bit, basically
185
00:10:42,180 --> 00:10:48,590
one step up, specifically asking a question, well, we we're
186
00:10:48,600 --> 00:10:52,910
guessing assuming the density and temperature a magnetic
187
00:10:52,920 --> 00:10:57,590
field, and the Corona is such a surge for as an input.
188
00:10:58,070 --> 00:11:03,080
But can I create the Corona in the first place from the layers?
189
00:11:03,890 --> 00:11:07,160
Bill, it's called chromosphere.
190
00:11:07,170 --> 00:11:10,160
And I said, that's exactly what all physicists do.
191
00:11:10,170 --> 00:11:14,570
They're trying to first recreate the Corona and then calculate
192
00:11:14,660 --> 00:11:17,450
Xray mission from the Corona, because that's the source of
193
00:11:17,460 --> 00:11:19,880
a mission and then the source of the wind.
194
00:11:20,140 --> 00:11:22,120
So, yeah.
195
00:11:22,240 --> 00:11:26,980
And I realized that, well, they use so called Iris, the telescope
196
00:11:26,990 --> 00:11:31,390
that measures the spectral signatures that are so vital to
197
00:11:31,400 --> 00:11:33,970
determine the energy flow at the lower level.
198
00:11:34,090 --> 00:11:36,760
I said, well, we have Hubble Space Telescope, the Hubble
199
00:11:36,770 --> 00:11:37,570
Space Telescope.
200
00:11:37,580 --> 00:11:42,190
It's absolutely fantastic instrument that's already there
201
00:11:42,610 --> 00:11:47,710
for the last 30 years, providing revolutionary information
202
00:11:47,720 --> 00:11:51,280
about different kinds of objects, including those young sons.
203
00:11:51,290 --> 00:11:55,180
And I looked at the data because way back, I was a member
204
00:11:55,180 --> 00:12:00,190
of the Hubble Special Stop team studying the old stacks.
205
00:12:00,200 --> 00:12:01,840
And I realized that, wow.
206
00:12:01,850 --> 00:12:02,020
Yeah.
207
00:12:02,030 --> 00:12:09,390
I have exactly the same fingerprint that Solaris is used
208
00:12:09,450 --> 00:12:12,510
from Hubble data, and they have the same quality.
209
00:12:12,930 --> 00:12:15,600
So, yeah, because the telescope is pretty big and the star
210
00:12:15,610 --> 00:12:16,320
is pretty close.
211
00:12:16,860 --> 00:12:19,050
And then I said, well, yeah, I can use that.
212
00:12:19,140 --> 00:12:22,830
And then I realized that we can also measure magnetic field,
213
00:12:22,840 --> 00:12:24,150
the magnetic field of a star.
214
00:12:24,210 --> 00:12:27,000
It's another important parameter because it drives everything
215
00:12:27,010 --> 00:12:30,150
else. It's the energy source of all those exclusive events
216
00:12:30,160 --> 00:12:31,830
of the Corona in the first place.
217
00:12:32,220 --> 00:12:37,230
And I started to collaborate with the Europeans, specifically
218
00:12:37,240 --> 00:12:39,960
with the University of Vietnam, scientists from University
219
00:12:39,970 --> 00:12:44,040
of Vienna who have a great experience and observing facilities
220
00:12:44,040 --> 00:12:46,620
to observe magnetic field and in contract them.
221
00:12:47,370 --> 00:12:51,080
So they supply the magnetic field for the star at different
222
00:12:51,090 --> 00:12:51,860
epics. Okay.
223
00:12:51,870 --> 00:12:54,440
Because the magnetic field, by itself changes is like your
224
00:12:54,450 --> 00:12:57,710
blood pressure may change from time to time.
225
00:12:57,770 --> 00:13:01,880
So that's why you had this very specific about the star at
226
00:13:01,890 --> 00:13:03,140
the given epic.
227
00:13:03,150 --> 00:13:03,290
Yeah.
228
00:13:03,300 --> 00:13:06,770
So this applied me the magnetic field and had the data from
229
00:13:06,780 --> 00:13:12,320
Hubble and synthesize them in one impose to feed the model
230
00:13:12,710 --> 00:13:17,420
and then to do calculations that we basically reported the
231
00:13:17,430 --> 00:13:19,400
results of which we reported now paper.
232
00:13:19,940 --> 00:13:20,940
Okay.
