Vol 4 Chapter 1133: Strange red dwarf

Entering the seventh day of the ruler seat α61.
"Results of detection scan on the seventh day, life response: none; logical signal: none..."
The detection team began routine reporting work, but the results were almost the same as the previous days, with no signs of life and no logical signals.
Logical signals mean to detect whether there are electronic signals emitted by intelligent species.
There is a clear difference between a logical electronic signal and a non-logic signal, which can be known by a little inspection.
"I have been tracking the traces of Palestine civilization for a few days. From the direction, it is slowly approaching the red dwarf star in the constellation α61."
"The observed information shows that the temperature and brightness of this red dwarf star are lower than that of a normal red dwarf star. Is it a bit abnormal?" Fang Yuan looked at the data for a while and turned to look at Lang Xiaonian. Get a reasonable explanation in astronomy.
Lang Xiaonian nodded and replied: "Indeed, the temperature and brightness of this red dwarf star are surprisingly low, much lower than normal red dwarf stars.
"From the perspective of spectral analysis, the surface temperature of this red dwarf is only 2000 degrees, or even lower.
"From an astronomical point of view, considering that α61 may be an ancient battlefield, all planets in the star system have been destroyed.
"Also, the alpha 61 red dwarf star in the constellation of the ruler should have evolved from a destroyed star.
"According to my speculation, the alpha 61 red dwarf star in the constellation of Rectangle was originally a star with a mass several times larger than the sun.
"After being destroyed, after an explosion, the mass was distributed to all corners of the star system.
"Even part of the mass is taken away by neighboring star systems. Of course, this process may take ten thousand years to calculate.
"After the big bang, after the war was gone, the α61 star system in the constellation of square meters began to cool.
"The broken star in the center cannot maintain the size of an A-type star, but the residual mass is still relatively large.
"Even if the Big Bang reduced the mass of the α61 star in the constellation of Rectangle by 90%, the remaining 10% of the mass would be enough to regroup into a star.
"Therefore, after the big bang, the matter at the center of α61, under the action of gravity, regrouped and formed the current red dwarf.
"At first, this red dwarf star may have only one-tenth of the mass of the sun. By continuously devouring the material left by the big bang in the star system, its mass has slowly increased to its current scale, which is about 0.2 times the mass of the sun.
"This process may continue for hundreds of thousands of years.
"According to astronomical research on main sequence stars, the surface temperature of a star with a mass of 0.2 times the sun should be 3,200 degrees.
"The temperature of this red dwarf star is indeed lower than expected, and it is much lower.
"There should be some reason for this result.
"According to my guess, it is most likely caused by different fusion materials."
Lang Xiaonian explained that, and glanced at everyone, not sure whether to continue.
Because if we continue to speak, more professional astrophysics knowledge will be involved.
"carry on."
Fang Yuan wanted to hear the answer, raised his finger and asked him to continue.
"Well, to explain the results of my analysis, you need to first explain the mass of stars and the type of stellar nuclear fusion..."
On the big screen, Lang Xiaonian released a data sheet of the thermonuclear reaction inside the star, and then explained: "From the table, we can see that the star generates heat because of nuclear fusion.
"But the fusion material is different, from the perspective of the thermonuclear reaction process.
"First, the hydrogen element undergoes a thermonuclear reaction, which produces helium.
"Next, the helium element undergoes a thermonuclear reaction.
"Next, is the thermonuclear reaction of carbon
"Oxygen, silicon...
"Until iron, the end of the thermonuclear reaction is reached.
"Therefore, in thermonuclear reactions, we often say that iron is the most stable element.
"Because, on the periodic table, the elements ranked before iron will release energy when they undergo nuclear fusion.
"However, after the iron, the situation changed.
"On the periodic table, the elements that are ranked behind iron undergo nuclear fusion and need to absorb energy.
"It's not wrong. For elements heavier than iron, nuclear fusion needs to absorb energy, and fission will release energy.
"The elements in front of iron are just the opposite. Fusion releases energy, and fission needs to absorb energy.
"Of course, in nature, it is almost impossible to carry out energy-consuming nuclear reactions, which makes iron unable to fuse and becomes the end of star death.
"However, not all stars can undergo all thermonuclear reactions until all elements are fused into iron.
"Because, starting from the hydrogen element, each stage of thermonuclear reaction requires more severe conditions.
"There is only one condition, and that is quality.
"The minimum requirement for helium to undergo a thermonuclear reaction is 0.5 times the mass of the sun.
"In other words, if a star wants to undergo a thermonuclear reaction with helium, its mass must be at least half the mass of the sun.
"However, the mass of the α61 red dwarf in the constellation of Rectangle is only 0.2 times the mass of the sun, which means that this red dwarf cannot undergo a thermonuclear reaction with helium.
"However, the star of α61 in the constellation of Rectangle was once a star with a mass much larger than that of the sun, which means that this star can undergo a helium thermonuclear reaction before it is destroyed.
"Therefore, I speculate that the material of the α61 red dwarf star in the constellation of Rectangle, before the Big Bang, had already fused a lot of helium, carbon, silicon...
"Now the mass is only 0.2 times the mass of the sun, and the helium, carbon, and silicon that have been formed cannot fuse.
"Only a small part of the hydrogen is left to continue the thermonuclear reaction. As a result, the surface temperature of this red dwarf star is lower than that of a normal red dwarf star.
"In a sense, we can regard this red dwarf star as a very old red dwarf star, even close to death.
"However, a red dwarf star under normal conditions has a longer life span than the universe. Under normal circumstances, it is impossible to produce such an old red dwarf."
Lang Xiaonian gave his own analysis. Although there is no evidence to prove that this inference is correct, it is very likely to be analyzed from the perspective of astrophysics.
After listening, everyone present felt a little surprised. They didn't expect such a strange star to appear in a destroyed star system.
After being quiet for a long time, Han Youwei raised her hand and said: "I still have one more thing to add. The Palestine civilization has obtained three special abilities from this.
"Analyzed from normal logic, it is usually life forms that can have characteristic abilities.
"Therefore, I think there may be life forms in the square seat α61, or it may be a special container preserved by life form fossils and ancient battlefield debris."
