Chapter 1133 Strange Red Dwarf

Enter the seventh day of Alpha 61 Square Square.

"Detection scan results on the seventh day, life response: none; logical signal: none..."

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

The meaning of the logic signal is just to detect whether there is the electronic signal emitted by the intelligent species.

There is a clear difference between a logical electronic signal and an illogical signal, and it can be known with a little inspection.

"For a few days, the fleet has been tracking the activity traces of the Palesean civilization. Judging from the direction, it is slowly approaching the red dwarf star of α61 Square Square."

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

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

"From the perspective of spectral analysis, the surface temperature of this red dwarf star is only 2000 degrees, or even lower.

"Analyzed from an astronomical point of view, considering that α61 Norma may be an ancient battlefield, and all the planets in the star system were destroyed.

"And the α61 Norma red dwarf should also have evolved from a destroyed star.

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

"After being destroyed, through the explosion, the mass is distributed to all corners of the star system.

"Even a part of the mass is taken away by the neighboring star system, of course, this process may take tens of thousands of years to calculate.

"After the Big Bang ended and the war was gone, the Alpha 61 Norma star system began to cool down.

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

"Even if the mass of the α61 Orgma star is reduced by 90% due to the big bang, the remaining 10% is enough to recombine into a star.

"Therefore, after the end of the big bang, the matter at the center position of α61 Metrima, under the action of gravitation,

Reunited to form the current red dwarf.

"In the beginning, this red dwarf star 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 the 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 3200 degrees.

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

"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 to this point, glanced at the crowd, not sure whether to continue talking.

Because if we continue to talk about it, it will involve more professional knowledge of astrophysics.

"continue."

Fang Yuan wanted to hear the answer, so he raised his finger to let him continue.

"Okay, to explain my analysis results, I need to explain the mass of the star and the type of nuclear fusion of the star..."

On the big screen, Lang Xiaonian released a data table of thermonuclear reactions inside stars, and then explained: "From the table, we can see that the heat generated by stars is due to nuclear fusion.

"But the fusion material is different, from the perspective of the thermonuclear reaction process.

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

"Next, there is the thermonuclear reaction of the element helium.

"Then, the carbon thermonuclear reaction

"The back 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 of elements, elements that rank before iron will release energy when nuclear fusion occurs.

"However, when it came to iron, things changed.

"On the periodic table of elements, the elements that rank behind iron need to absorb energy for nuclear fusion to occur.

"That's right, 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 nuclear reactions that consume energy, which leads to the inability of iron to fuse and becomes the end of the death of stars.

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

"Because, starting from hydrogen, each level of thermonuclear reaction requires more stringent conditions.

"There is only one condition for this, and that is quality.

"In order for helium to undergo a thermonuclear reaction, the minimum requirement is 0.5 times the mass of the sun.

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

"However, the mass of the α61 Angularis red dwarf is only 0.2 times the mass of the sun, which means that this red dwarf cannot undergo helium thermonuclear reactions.

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

"Therefore, I speculate that the matter of the α61 Angularis red dwarf star has fused a lot of helium, carbon, and silicon before the big bang...

"Now the mass is only 0.2 times the mass of the sun, and the formed helium, carbon, and silicon cannot be fused.

"Only a small part of the hydrogen is left to continue the thermonuclear reaction, resulting in a lower surface temperature of the red dwarf than normal red dwarfs.

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

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

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

After listening to it, 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 have one more thing to add, the Palesi civilization got three characteristic abilities from here.

"Analyzed from the normal logic, those who can usually have characteristic abilities are generally living organisms.

"So, I think that there may be living organisms in α61 Rectangular, or it may be the characteristic container preserved by the fossils of living organisms and the remains of ancient battlefields."
