Great Country Academician

After tidying up the manuscript paper on the table, Xu Chuan stood up and stretched.

Although the calculation this time is a bit troublesome, it should be done tonight. As for now, let's go to dinner first.

After all, he missed it, and he didn't bring any snacks, so he couldn't get something to eat at night.

On the first floor, in the dining room of the base of the Astronomical Research Station, Xu Chuan was picking food in the cafeteria with a plate, and bumped into several Senior Brother Nan who also came to eat.

"Hi, Chuan Shen."

"Junior Brother Chuan."

"."

Facing him, several seniors greeted Xu Chuan with a plate, and enthusiastically recommended to him the best-tasting food in the canteen, 'Fried Golden Chicken Drumstick', which was actually just fried chicken drumsticks coated in breadcrumbs.

But here, it's already the best thing to eat.

No way, astronomical observatories are no better than astronomical exhibition halls. Observatories with large-scale scientific research equipment are basically built in barren mountains and ridges, and the surrounding tens of kilometers are deserted. It is very troublesome to transport materials in, and some food is good.

"Chuanshen, how is the calculation of the mass of Betelgeuse? When will the results come out?"

In the restaurant, several people from Nantah University sat together, chatting about scientific research work while eating.

"Tomorrow should be almost there, but it is not certain whether the first set of data can be used to calculate the mass of the companion star in the hydrogen envelope. There may be problems with the data, and it is not complete."

Xu Chuan took a bite of the fried golden chicken leg and said, there are some things that no one knows the answer until the end, not to mention that the data he brought back before is not complete, and some things are missing.

During the fusion calculation this afternoon, he used scattered data to do some area calculations, but the results for him were not very good.

Maybe this time the mass calculation is missing some key data, such as the polarization of Betelgeuse that can only be observed with a radio telescope at the Ching Hai Observatory.

This thing is a very important parameter in the Xu-Weyl-Berry mass calculation equation. It can be used as auxiliary information to define the boundary value. Without this, the calculated data will most likely have problems and may have large deviations.

After a pause, after swallowing the chicken in his mouth, Xu Chuan then asked, "When will the work on your side be finished? How long will it take for Qing Hai to finish?"

Hearing this, Senior Brother Liu Xuan, who led the team, put down his chopsticks, thought for a while and said: "There will be no rain in the south of Yunnan for the past two days. If the weather is good, we should be able to get it done the night after tomorrow."

"As for Qing Hai, I'm not sure, especially about the polarization of the companion star. After all, we don't even know whether the companion star exists or not, and how long the return period is."

"People's radio telescopes also have their own work assignments. This time, I can jump in the queue and use them for a week, which is beyond my imagination."

"The only thing you can do is to keep collecting data for a period of time while observing the data you need, hoping that the data during this period will have the information you need."

"I hope that I can observe the companion star in this week, otherwise I can only hope on the previous observation data of Betelgeuse, or, after this period of time is over, I will apply for a radio telescope to have a look."

From the beginning, they only participated in scientific research projects to get some qualifications, and now, these doctoral students from the Department of Astronomy have devoted themselves to it.

There may be an accompanying star in the hydrogen envelope of Betelgeuse. If this discovery is confirmed, the results will shock the entire astronomical community.

With such a discovery, even a doctoral student like Liu Xuan who is about to graduate and has written half of his graduation thesis can give up his original thesis and transfer his graduation thesis to this aspect instead.

Compared with the previous graduation thesis, this discovery can be described as world-class.

And if it is really successful, it means that through this scientific research experiment, people will master the key methods to calculate the mass, volume, diameter and other information of stars in distant galaxies.

Although they were hired, it is undeniable that they participated in the whole process of this scientific research experiment, and the key data of Betelgeuse and its companion star were all collected by their observations.

It's no longer mixed qualifications, but gold-plated, or a thick layer of dazzling gold. As long as they succeed, they will be snapped up by various astronomical units after graduation.

So from the beginning of normal work, they have already cared more about this scientific research project than Xu Chuan.

After dinner, Xu Chuan returned to the laboratory, packed up the manuscript papers and opened a room for accommodation.

The observatory still has a guest house. After all, foreign scholars and scientific researchers often come here to carry out experimental research and need accommodation.

It's just that the environment of the guest house is very ordinary, even worse than the hotels in ordinary small county towns, and some of them have double rooms and multi-person rooms.

Xu Chuan applied for a single room. Although he is only a college student now, according to the rules, he cannot apply for a single room, but his situation is quite special. The leaders of the observatory know some things and don't pay much attention to them.

After taking a shower and wiping his hair clean, Xu Chuan took out the manuscript paper from his backpack and continued to finish the unfinished work in the afternoon.

According to the calculation, the time is very fast, and in the blink of an eye, the sky outside is completely dark.

". Substitute the blackbody radiation data uλ(v, T)=4π/λ., the mass is 23.871911123M⊙, 2.706358293M⊙"

Staring at the calculated data, Xu Chuan put down the pen in his hand and rubbed his sore eyes.

"Sure enough, after losing the amount of polarization to define the boundary value to an accurate quasi-value, the calculated quality data is problematic."

After glancing at the data on the manuscript paper, Xu Chuan shook his head slightly.

The quality of 23.871911123M⊙, this data is not accurate at a glance.

It far exceeds the current estimation of the mass of Betelgeuse by the astronomical community.

Although the astronomical community has not unified the mass of Betelgeuse at present how many times the mass of the sun, some data show that its mass is only 14 ~ 15 M⊙, but some data believe that its mass reaches 18 ~ 19 M⊙, and even some up to 20 M⊙.

But there are almost never estimates beyond 20 solar masses.

23.87 times, close to 24 times the mass of the sun, this number obviously exceeds the previous estimates of the astronomical community.

Although it is possible that it is correct, the probability of this is small.

On the one hand, the astronomical community has used conventional methods to calculate the mass of Betelgeuse over the years. Although it is not accurate, the general mass will not be wrongly estimated.

On the other hand, the data parameters he used to calculate Betelgeuse this time are not complete. After the lack of key auxiliary information such as the polarization amount, the calculated amount must be biased.

But there is good news. The first group of data, the information about the quality, also calculated two groups.

This confirms that there is indeed a companion star that has never been discovered before in the hydrogen envelope of Betelgeuse.

Two sets of diameters, two sets of masses, this can no longer be said to be a calculation problem.

Perhaps these data are not enough to fully confirm that there is a companion star in the hydrogen envelope of Betelgeuse. After all, the source of data calculation is a bit monotonous, and it is uniformly derived from a set of observation data, and there is a possibility of error.

But there is already a probability of more than eighty or ninety percent.

If several sets of the same data can be observed in the next time, it can be confirmed.

It is really necessary to confirm this discovery. For the astronomical community, this may be the biggest discovery of the year.

After double-checking the calculation process and data, and confirming that there were no errors, Xu called and called several doctoral students from Nantah University over.

Although it was eight or nine o'clock at night at this point, the brothers must have not slept, and they had to use the observation array at the observatory to collect data on Betelgeuse in the early hours of the night.

"Still Chuan Shen is amazing, actually living in a single room, I am so envious, my mentor and I both lived in the standard room when we came here."

"If you prove a world-class conjecture, you can hope to win the Fields Medal."

"Okay, don't be poor, Chuan Shen suddenly called us over this time, there must be a major discovery. Has the mass data of Betelgeuse been calculated, Chuan Shen?"

Several doctoral students came in and packed the small room to the brim.

Xu Chuan ignored the other people's ridicule, looked at Liu Xuan who led the team, and said: "The data is calculated, and it is the same as the diameter before, and the data calculated by taking the first set of information data also calculates two different results. "

"That is to say, there is a high probability that an accompanying star is hidden in the hydrogen envelope of Betelgeuse."

"However, key auxiliary information such as polarization is missing at present, and the calculated numerical error is very large."

Hearing this, Liu Xuan's eyes lit up, and he hurriedly asked, "Where's the data? Can I see it?"

Both the diameter and the mass have been calculated into two groups, which is enough to confirm that part of the data in the first group does not come from Betelgeuse, but from other stars.

The two groups of simple diameters can also be said to be caused by calculation errors or problems with observation data.

But add another mass, and the probability of confirming the existence of the companion skyrockets.

On this basis, the probability of a companion star inside Betelgeuse's hydrogen envelope exceeds 90 percent.

If they can observe several sets of companion star data later, they can directly confirm the existence of the companion star.

As for the data deviation, that is not a problem, no matter how big the deviation is, after all, the data itself is not complete.

Including the previous diameter calculation, it is actually not completely accurate, because some key values ​​that they have not observed are all extracted from the original ancient observation data.

What we are doing so far is just to verify whether the Xu-Weyl-Berry theorem can accurately calculate the size of Betelgeuse. Once the data collection is complete, it will be enough to calculate it again.

So it doesn't matter if it is the final precision value now or not.

Xu Chuan pointed to the manuscript paper on the table, and said, "It's over there."

Liu Xuan walked over quickly, picked up the manuscript paper on the table, and looked directly at the final answer.

Although he is a doctoral student, he really can't understand the calculation process on the manuscript paper.

He had seen the formula and process of calculating the diameter before, but he couldn't understand it at all, so he just looked at the answer directly.

【23.871911123M⊙】

【2.706358293M⊙】

Two answers, the first is close to 24 times the mass of the sun, it should be Betelgeuse, the second is close to 3 times the mass of the sun, it should be the companion star inside.

Such a large mass, even if there is a deviation, more than 50%, or even more than eighty or ninety, is enough to prove that if the companion star inside really exists, it is definitely a star, not a planet.

It's very simple, because the planet has a mass limit.
