In the fourteenth line, there is also a significant difference in the surface temperature of Betelgeuse, but this cannot be referenced.

Because the surface temperatures of the other fifteen groups also vary greatly, with the highest surface temperature of Betelgeuse reaching 3,400 degrees and the lowest being only 2,500 degrees.

This is caused by the frequent celestial activities of Betelgeuse, just like sunspots, flares, solar radiation and other activities on the sun.

It's just that the sun's activity is much weaker than that of Betelgeuse. If it were as violent as Betelgeuse, the earth would either turn into toast or become a frozen world, and the two would reincarnate repeatedly.

Just like the weather in Star City, you experience spring, summer, autumn and winter one week, and winter, autumn, summer and spring again next week.

In addition, there are some other subtle gaps on this form, but they are not as obvious as these three information-awareness features.

After thinking about it, Xu Chuan slightly modified the original values ​​based on the original values ​​in the ninth and eleventh rows, making them larger or smaller, and then reused this data to perform calculations.

Soon, a new set of data was calculated.

A group【908.d⊙】

Group 2【131.d⊙】

Two sets of completely different values ​​came into Xu Chuan's eyes again.

"Is it such a big impact?"

Staring at the values ​​calculated on the manuscript paper, Xu Chuan whispered to himself. The values ​​he artificially created did not significantly adjust the original values. It could even be said that they only increased by about 5%.

However, the answers of the second group soared more than twice on the original basis.

The diameter has increased directly from the original 67.45d⊙ to 171.31d⊙.

After thinking about it, Xu Chuan took out the phone from the table and called his doctoral student brother who was collecting Betelgeuse data for him in southern Yunnan.

After briefly introducing the situation on his side, Senior Brother Liu Xuan, who was leading the team on the other end of the phone, immediately screamed.

"What? Two diameters?"

"This is impossible. How can a star have two diameters, and the difference is so big? One group has nearly 900 d⊙ units, and the other group has less than 100."

"Junior brother, have you ever considered that there was a problem with your calculations?"

Xu Chuan could understand Liu Xuan's fierce rebuttal. He couldn't believe it when he first calculated it, but he was more calm.

This chapter is not over, please click on the next page to continue reading! "I know this is not scientific, but the numerical value calculated through the xu-weyl-berry theorem is indeed like this..."

"That may be a problem in the calculation process. A star, even a star with intense activity in its later years like Betelgeuse, will have different diameters, and it is impossible for the deviation to be so large."

On the other end of the phone, before Xu Chuan could say anything, Liu Xuan's retort came over.

Xu Chuan glanced at the manuscript paper on the table and said: "I have calculated all the sixteen sets of data I brought back. Fifteen of them have only one diameter, which is around 889d⊙ units. The numbers can be accurate to the first decimal place.

Eight."

"This is enough to prove that there is no problem with my xu-weyl-berry theorem. It can accurately calculate the diameter of Betelgeuse."

"But among these sixteen sets of data, one set of data calculated two answers..."

Xu Chuan didn't finish what he said, it was enough at this point.

"You mean there is a problem with a set of Betelgeuse data we observed?"

On the other end of the phone, Liu Xuan also gradually calmed down, and after listening to Xu Chuan's analysis, he frowned and asked.

He didn't really believe that there was something wrong with the observation data.

Because the data handed over to Xu Chuan has been checked by him personally, if there are any problems, they should have been discovered during the verification.

But since there is a problem, it must be solved.

So let’s see where the problem is first.

"Well, the preliminary judgment is this."

Xu Chuan responded without saying another sentence: "In addition to the possible problems with the data, there is another possibility, that is, when this set of observation data was recorded, some unknown changes may have occurred on Betelgeuse, thus affecting the data."

Hearing this, Liu Xuan frowned again. Has Betelgeuse undergone unknown changes?

What changes could cause such a large diameter difference?

After thinking for a while, Liu Xuan said: "Let's do this, you can send that set of data to my email, and I will analyze it urgently tonight. I have all the original data of the observation data in my hand. If there are changes in Betelgeuse,

Through that information, we should be able to analyze something."

Xu Chuan nodded and said: "Then I'll bother Senior Brother Liu. I'll book a ticket for tomorrow to go to southern Yunnan."
