The seventh day of entering the phalin α61.

"The seventh day detection scan results, life reaction: none; logical signal: none..."

The detection team began routine reporting, but the results were almost exactly the same as before, with no signs of life or logical signals.

The meaning of logical signals is to detect whether there are electronic signals emitted by smart species.

There is a clear difference between logical electronic signals and unlogical signals, and you can know it with a slight detection.

"For a few days, the fleet has been tracking the movements of the Palesey civilization. From the direction, it is slowly approaching the red dwarf of the α61 zodiac sign."

"The observed information shows that the temperature and brightness of this red dwarf are lower than that of a normal red dwarf. Isn't it a bit abnormal?" Fang Yuan looked at the data for a while, turned to look at Lang Xiaonian, hoping to get a reasonable explanation in astronomy.

Lang Xiaonian nodded and replied: "Indeed, the temperature and brightness of this red dwarf are surprisingly low, much lower than that of a normal red dwarf.

"From spectral analysis, the surface temperature of this red dwarf is only 2,000 degrees, or even lower.

"From an astronomical perspective, considering that α61 of the magnitude may be an ancient battlefield, and all the planets in the stellar system were destroyed.

"And the red dwarf of the α61 constellation should also evolved from a destroyed star.

"According to my speculation, the red dwarf of the α61 constellation should have been a star with a mass several times larger than the sun.

"After being destroyed, after explosion, the mass was distributed to every corner of the star system.

"Even part of the mass is snatched away by adjacent star systems, of course this process may have to be calculated in units of ten thousand years.

"After the Big Bang and after the war was gone, the α61 star system of the celestial stalk began to cool down.

"The broken stars at the center cannot maintain the size of the A-type stars, but the residual mass is still relatively large.

"Even if the big explosion caused the mass of the star α61 of the magnitude constellation to be reduced by 90%, the remaining 10% of the mass is enough to repolymerize into a star.

"So, after the end of the Big Bang, the matter at the center of the α61 position of the magnitude α61 regrouped under the action of gravity to form the current red dwarf.

"At the beginning, this red dwarf may have only one-tenth of the mass of the sun. By continuously devouring the material left by the big explosion in the star system, the mass gradually increased to its current scale, about 0.2 times the mass of the sun.

"This process may continue for hundreds of thousands of years.

"According to astronomy's research on main sequence stars, the surface temperature of stars with a mass of 0.2 times the sun should be 3200 degrees.

"But the temperature of this red dwarf is indeed lower than expected, and it is much lower.

"There should be some reason that led to this result.

"According to my guess, it is very likely that it is caused by different fusion substances."

Lang Xiaonian explained that he had just scanned everyone, not sure whether to continue talking.

Because if you continue speaking, you will need to involve more professional knowledge of astrophysics.

"continue."

Fang Yuan wanted to listen to the answer, so he raised his finger and asked him to continue.

"Okay, if you want to explain my analysis results, you need to explain first the mass of the star and the type of stellar nuclear fusion..."

Lang Xiaonian released a data sheet for internal thermonuclear reactions on the big screen, and then explained: "From the table, we can see that stars generate heat because of nuclear fusion.

"But the fusion materials are different, from the perspective of the thermonuclear reaction process.

"First, hydrogen element undergoes a thermonuclear reaction, and this reaction process produces helium.

"Immediately afterwards, the helium element carries out the thermonuclear reaction.

"Then, the carbon thermonuclear reaction is

“There is oxygen, silicon…

"It is not until iron that the end point of the thermonuclear reaction is reached.

"So, in thermonuclear reactions, we often say that iron is the most stable element.

"Because, on the periodic table, the elements that are before the iron element will release energy when undergoing nuclear fusion.

“But, after I arrived at the iron, the situation changed.

"On the periodic table of elements, the elements behind iron, need to absorb energy when undergoing nuclear fusion.

"No mistake, elements heavier than iron need to absorb energy when undergoing nuclear fusion, and fission will release energy.

"The elements in front of iron are just the opposite. Fusion releases energy, and it is necessary to absorb energy to fission.

"Of course, in nature, it is almost impossible to carry out nuclear reactions that consume energy, which leads to iron being unable to fusion and becomes the end point of star death.

"However, not all stars can carry out all thermonuclear reactions until all elements gather into iron.

"Because, starting from hydrogen, the more harsh the conditions required for each level of thermonuclear reaction.

“There is only one condition, that is quality.

"If he wants to have a thermonuclear reaction in helium, the minimum requirement is 0.5 times the mass of the sun.

"That is, if a star wants to undergo a thermonuclear reaction of helium, its mass must reach at least half of the mass of the sun.

"However, the mass of the red dwarf of the α61 constellation is only 0.2 times the mass of the sun, which means that this red dwarf cannot carry out the thermonuclear reaction of the helium element.

"However, the star of α61, once was a star with a much larger mass than the sun, which means that this star could undergo helium thermonuclear reaction before it was destroyed.

"So, I speculate that before the big explosion, the matter of the α61 red dwarf had already fusion of 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 be fusion.

"Only a small part of the hydrogen remains to continue the thermonuclear reaction, resulting in the surface temperature of the red dwarf being lower than that of the normal red dwarf.

"In a sense, we can regard this red dwarf as a very old red dwarf, and it is even close to death.

"However, under normal circumstances, red dwarfs have a longer lifespan than the universe. Under normal circumstances, it is impossible to produce such an old red dwarf."

Lang Xiaonian explained his analysis. Although there is no evidence to prove that this inference is correct, from the perspective of astrophysics, the inference is extremely likely.

After listening, everyone present was a little surprised. Unexpectedly, such a strange star would appear in a destroyed star system.

After a long quiet time, Han Youwei raised her hand and said, "I have another point to add. The Palesey civilization has obtained three characteristics and abilities from here.

"Analyzing from normal logic, usually life forms that can have characteristics and abilities are usually alive.
