Chapter 232: Half a star

With the development of science and technology to the present level, Xiao Yu is confident and has the confidence to make such a commitment. Anyway, in Xiao Yu's opinion, everything is just a consumption of computing power. Creating some entertainment facilities, cooking some food, or breeding some things that they think are "beauties" through biotechnology, the computing power consumed is much less than the computing power consumed by painstakingly studying technology. .
This is a stable business without losing money.
The treatment enjoyed by the Lucca civilization is somewhat different from those of those captured. After this long period of getting along, the abilities and loyalty of the scientists of the Lucca civilization have been verified. The treatment given to them by Xiao Yu is in addition to the material life treatment equivalent to or even beyond that of other civilizations, and there is one other civilization that is extremely The most precious thing to look forward to and dare not expect is dignity.
No matter how much Xiao Yu has done for those captured alien scientists and how well they have been treated, they are always just a cargo in Xiao Yu's eyes, when they are in danger or their value is not equal , They will be abandoned by Xiao Yu without hesitation. Luka civilization is not. If it wasn't Luka scientists who were trapped in the sky blue market, but scientists from the rest of the civilization, Xiao Yu would rescue them, and say two more things.
During the time of entering the voyage of curvature, Xiao Yu held an extremely grand reward ceremony for Lucca II, and gave it the most honorable position among the Lucca civilization. Looking at the slightly envious and jealous eyes of Luca III and Luca 4, Xiao Yu was very proud: "It is for you to envy and envy Luca II that you have the motivation to work harder for me. "
In sharp contrast, these were the captured Merian civilization. Xiao Yu has lost the patience of surrendering them, because Xiao Yu finds that no matter what means he uses, they will not work for them. The punishment also does not work if the differentiation method does not work and the differential treatment method does not work.
"I don't know how the creatures in their civilization have such a strong loyalty." Xiao Yu thought for a moment, and simply frozen all of them, while at the same time saving some resources. Xiao Yu intends to sell all of them after they are thawed and resurrected after meeting the trading market.
Time is slipping away in such a vigorous and vibrant state.
Gradually, twenty years have passed, and the fleet of the Merian civilization has never followed. At this point, when Xiao Yu's mind was relaxed a little, there was some doubt.
"Did there be some kind of limitation of the fast light detection instrument based on the fast technology, or I simply ran too fast and they didn't have time to catch me? So they didn't catch up? Well ... no matter what, It's always good. I've escaped a distant distance of 250 light-years, which is far enough, right here. There is a star here, and a planet orbiting around it, which is suitable for the development of science and technology. A good place. "Xiao Yu thought, retreating from the curvature of navigation.
"Seeing the starry sky again is so beautiful." Xiao Yu, who withdrew from the curvature of the voyage, once again received the visible light signal. Looking at the beautiful starry sky, she couldn't help but sigh.
The dark universe is like a huge black cloth that fills the heavens and the earth. On this black cloth, the stars are like beautiful gems dotted on it. There is a certain pattern in the density distribution of gems. The more they go to the opposite direction of Xiao Yu, the more sparse they are, the more dense they will be.
Here, the Milky Way can be clearly seen, and its shape is somewhat different from that seen on Earth. On a clear summer night, the Milky Way seen above the earth is in the shape of a long strip. At the position where Xiao Yu is, the shape of the Milky Way seen has a circular trend. It consists of a belt , Into an extremely flat oval.
Moreover, from Xiao Yu's position, several cantilever arms of the galaxy can be clearly distinguished, such as the fairy arm and the swan arm. Even the Orion's arm, where the sun was, was striking.
This shows that Xiao Yu, who has been running around for more than 10,000 years after leaving Earth, has left the Orion arm. Xiao Yu found out where he is currently by comparing the Qin Ying Chuangluo Lu with measurements of some reference neutron stars.
"I ... probably a bit outside the middle of the arm of the horse, about five thousand light-years away from the current sun. Hey, when you have time, go back to your hometown and take a look." Xiao Yu wondered, "I don't know if any other creatures have entered the solar system during this time, I don't know if my base on Titan is still there. Those wood spirits, and Venus, Mars, I don't know what is happening now. "
While looking at the direction of the sun, Xiao Yu's thoughts were stirred, while he was sailing toward the target star in the usual way.
Here, there is a relatively dense area of ​​stars. The distance between the two nearest stars is generally not more than five light years. This distance is not much different from the density of the area where the sun is located.
Similarly, the distance from Yinxin to this place is similar to the distance between the sun and Yinxin, which is about 230,000 light-years.
Xiao Yu's target star is a red dwarf. Its mass is only one hundred and eighty times the mass of Jupiter. This mass is less than one fifth of the sun.
This mass means an extremely long life. In the universe, there are many phenomena that seem to violate common sense. For example, a star has a smaller mass and a longer life, but a black hole is just the opposite. A black hole with a larger mass has a longer life. The general matter is always the larger the volume, the greater the mass, but not the neutron star and the white dwarf. The smaller the neutron star and the white dwarf, the greater the mass.
This red dwarf planet is more suitable as a companion star than a planet. The companion star is a brown dwarf, which has reached twenty times the mass of Jupiter. Because its mass is too small, it cannot maintain its luminosity through hydrogen fusion and cannot become a main sequence star. However, deuteron fusion can occur inside them, so there is still a certain amount of energy radiating from it. This energy is mainly emitted in the form of infrared rays.
It does not emit visible light, so this type of brown dwarf is extremely difficult to observe in the universe, and they can usually be seen only through astronomical telescopes in the gravitational swing method and infrared bands.
This pair of stars, in the universe, work together around an invisible point. This point is their particle.
The two stars are orbiting to form a two-star system. If the mass difference is not too large, then they constitute a two-body problem. Unlike the three-body or multi-body problem, the two-body problem has a clear solution. Xiao Yu saw that this pair of double stars is following each other in a predictable and stable orbit.
In this stellar system, unexpectedly Xiao Yu expected that there is still a rocky planet. This rocky planet is about the same mass as Mercury, and it is orbiting the brown dwarf.
Brown dwarfs are called "failed stars". They are a kind of star between a gas giant and a low-mass star, so the status of this planet is very awkward. One of the definitions of planets is that planets must orbit stars, but whether brown dwarfs can be called stars is really something worth exploring.
"For the time being whether brown dwarfs can be called stars or whether this planet with a mass of approximately Mercury is a planet or a satellite, in short, they can bring me sufficient supplies." Xiao Yu thought, tangling the one The problem threw his head.
In addition to this Mercury-sized star, there are many asteroids in this binary system, and the number is expected to reach 10 million. There are also many comets made of volatile gas, as well as dwarf planets, tiny rocks, etc., which together constitute this vibrant star system.
Xiao Yu's huge fleet braved the rain of these guns, and marched towards the rocky planet. Xiao Yu will be stationed here, UU reading www.uukanshu. With the help of the abundant material resources here, COM combs through its current scientific and technological system comprehensively and in detail. At the same time, it speeds up the research and development process of new technology. After having new results, it upgrades its spaceship once again.
While moving forward, Xiao Yu also operated a telescope equipped on the spacecraft to detect surrounding stars.
"Well, the type of stars around this binary system is quite rich. There is actually a red giant star there ... and it has fifteen times the mass of the sun. This means that a supernova explosion will happen soon. There It's a yellow dwarf, and a red dwarf ... "
Xiao Yu, while observing, recorded these data.
"Well? This star isn't right." After the telescope's barrel turned to another direction and aimed at a seemingly ordinary star, Xiao Yu quickly found out what was wrong.
There are only half of this star.
In Xiao Yu's sight, only half of the star was glowing, and the other half was completely dark, not only in the visible light band, but not in the infrared or ultraviolet bands. Even Xiao Yu wasn't sure if there was anything there.
"What's going on? Is there such a thing in the universe?" This star shocked Xiao Yuda. If this kind of thing can really exist in the universe, then more than 90% of Xiao Yu's scientific theory will be overthrown.
That star is undoubtedly a star, and it can be easily distinguished by spectral measurement, photometric analysis, etc. of the half that emits light. But it was only half glowing. This makes it look like a moon in a semicircle and is weird.
