If Sirius broke out, will it destroy the ecology of the earth?

Sirius is one of the stars closest to the earth with the naked eye, about 8.6 light years from us. If this star broke out, will it be great energy, will it destroy the ecology of the earth, or is there still saving humans?

Now, let's analyze it based on the common common sense of science.

Let's talk about Sirius what kind of star is

In fact, the nearest star is the neighboring star, about 4.22 light years from us, but this is a small red dwarf, with a quality of about 12%of the sun, so human beings are invisible to the naked eye. But the neighboring star is a three -star star system, and the remaining two are called South Gate two A and B. The quality is similar to that of the sun. It is a bright star in the eyes of human eyes.

The stars closer to us are also Banard Star. This is also a red dwarf. The quality is about 15%of the sun, and the naked eye is invisible. At a distance is Sirius, about 8.6 light years from us. It is the brightest one in the stars except the sun.

Sirius is a double star system. We see the brightest star is Sirius A. This is a blue dwarf, which is about 2 times the quality of the sun, 1.7 times the diameter of the sun, about 10,000k on the surface, star The age is about 242 million years old, with a life span of about 1.76 billion years.

The sun is a yellow dwarf, with a mass of about 2*10^30 kg. Stars with a greater quality and brightness than the sun are called blue dwarfs. However, no matter the yellow dwarf or the blue dwarf, the stars with a mass of more than 0.5 times to 8 times the solar quality have become a red superstar at the end of the evolution. After that, the peripheral gas material gradually expands and dissipates in space, leaving a white dwarf at the core.

Modern astronomical physics believes that only a star with sufficient quality can occur in the later period of the supernova. This quality requirement is at least 8 times that of the sun. After the evolution of the core hydrogen fuel after the core hydrogen fuel was burned, the huge gravity pressure will cause nuclear fusion chain to occur, and the final collapse will cause thermal nuclear out of control and bomb the shell and even the entire star body.

According to this evolutionary law, Sirius A has no chance to become a supernova. But the problem is that Sirius is a double -star system. The so -called double -star system is that two stars are tied together under the action of gravity. Sirius B is a companion with less than Sirius A, but in fact, it is a dying star ~ white dwarf.

The quality of this white dwarf is similar to that of the sun, which shows that it was a star that was greater than Sirius A before his death. Astronomor's modeling estimates that Sirius B is likely to be a blue dwarf about 5 times the quality of the sun before his death.

White dwarf is a kind of high -density and special celestial body. Because its volume is extremely small, the quality is as large as the sun, and the volume is only as large as the earth. Therefore Material, as high as 1 to 10 tons per cubic cubic cubic cubic cubic meter.

Although the white dwarf is a kind of star corpse, it is dead but not stiff. Due to its great gravity, it will adsorb the interstellar material close to itself, also called the accumulation. Studies have found that the maximum limit of electronics can only support 1.44 times the quality of the solar. This law is discovered by an Indian physicist named Subramannan Chandlaseka. This boundary is called Chandraseca limits.

When the white dwarf accumulation increases its own quality to the limit of Chandraseca, the gravity will cause the star body to further collapse, and the electronic simplification to the neutron star and the sudden change. The carbon nuclear fusion of the star body cannot be released in an instant, and the heat out of control causes huge energy to explode. This outbreak is called the LA -type supernova.

Will Sirius B exceed Qian Draseca limit?

My answer is very likely. This is because Sirius's dual -star system is not far away. The average distance between the two stars is about 20AU, which is 20 astronomical units, that is, the average distance from the earth to the sun, about 150 million kilometers, 20AU is about 3 billion kilometers. Essence

Sirius B has to increase its own quality to 1.44 times the quality of the solar. It is not enough to have a little dust on the empty space. It must absorb a lot of material on Sirius A to increase its own quality to Qiande to Qiande Laoseka limit.

Our solar system has only one star. The gravity of the sun locks eight major planets and several dwarf planets, as well as hundreds of planetar satellites and countless small asteroids, dust, etc. The scope of the gravity affects more than 1 light years. There are 30au from the planet Neptune, the farthest from the sun, and Pluto is 40AU.

Sirius double star is only 20AU, so it is not impossible to get some food from Sirius A.

However, it seems difficult to get from A to 0.44 from A to 0.44 from A, and it is difficult to achieve it in the sky. Opportunities may happen when Sirius A is at the end of his life, that is, 1.5 billion years later. After the core of the Sirius core is burned, the nuclear fusion will evolve all the way towards the sequence of the sequences of crickets, lithium, 铍, boron, and carbon, and eventually reaches the end of carbon.

At the same time, its peripheral substance expands due to star gravity and internal radiation changes, and the radius of the star will be expanded by 200 to 300 times. In this way, Sirius A with a radius of about 1.19 million kilometers has become a red superstar radius of about 238 to 357 million kilometers. Nevertheless, the distance between the two stars is still far away. The opportunity of B -star is that the expansion of A -star will continue. In the end, about 70%of the substances on the periphery of the planet will spread to the surrounding space. In this way, there will be many displaced interstellar substances captured by Sirius B's huge gravity. Sirius A lost to the 1.4 times the quality of the solar quality of space, can it be eventually captured by Sirius B to achieve a shocking quality? It's hard to say.

However, because these two stars are entangled with each other, about 9.1 years of cycle, in such a cycle, Sirius B is likely to be greedy like a computer game to eat snakes and beans. Eating a fine light is enough to gather the shocking energy.

How much energy does Sirius explosion into a supernova and what does it affect the earth?

The supernova erupted by the white dwarf is called the LA supernova, and its outbreak conditions follow Chandraseca's limit, which is 1.44 solar quality. Therefore, all LA supernovas are extremely standard energy outbreaks. The energy of the outbreak is equivalent, and the brightness and light curve of the outbreak are basically the same.

In this way, as long as the outbreak of this LA supernova burst, no matter how far the outbreak happens, the absolute star should be the same. But the distance is different, the stars' viewing stars are different, that is, the brightness that you see is different. These two brightness can be converted. How long can this explosion occur through converts, so this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this kind of this kind of explosion, so this is this kind of explosion. Therefore LA supernova is called the standard candlelight in the universe.

The energy from the cosmic celestial body is directly proportional to the brightness, so as long as the celestial body brightness is obtained, its energy can be calculated. The benchmark for measuring the brightness of the celestial bodies is the star, etc. The absolute star refers to the brightness of the glowing celestial body at the position of the 32.6 light years, and the viewing star is the brightness that the human eye can see.

The brightness of the star is the smaller the brighter, the more loser the lighter, and the brightness of each star is 2.512 times. The absolute star of the sun is 4.83, and the absolute star of LA supernova erupted was-19.5, which is about 4 billion times the brightness of the sun.

When the supernova erupted, the radiation energy can reach 10^46 coke ear/second, and the radiation energy of the sun is 3.78*10^26 scorched ear/second. Said that the energy of LA supernova erupted radiation is quite 1 trillion yuan of solar radiation energy, and the total amount of radiation in the lifetime of 83 solars.

So, if the LA supernova burst occurs in Sirius position, what does its energy affect the earth? Some people say that the outbreak of the supernova can destroy all the lives of the 50 light -year radius. How do we understand this power?

Scientific research believes that the supernova explosion will explode the entire star as extremely fine particles. These high -energy -with -point particles spread to the surroundings by turbulence. The fastest time can reach more than 20,000 kilometers in seconds, close to 7%of the speed of light! These shock waves will reach the earth as soon as 122 years, and it is likely to lead to species extinction.

The earliest arrival was of course the explosion light, which arrived at 8.6 years at a speed of light. How big is this brightness? We have replaced the formulas such as absolute stars and other visual stars: M = M-5log (D0/D). According to LA Super Navigation Star Absolute Star, M is about -19.5. The view stars are about -22.39 and so on.

The sun is the nearest star to us, and the stars are -26.7; the moon is the nearest extra-ground celestial body, relying on reflecting the sunlight at the full moon as -12.7; and Sirius broke into the supernova view of the supernova. Stars are about -22.39 and so on. From this point of view, the supernova erupted by Sirius still has no sunlight, and the brightness is dozens of times; but the brightness of this supernova is already the brightest celestial body in the sky, which is 7520 times the brightness of the moon.

In this way, during the period when Sirius broke into a supernova, people can see a very bright star in the sky. As long as it does not coincide with the sun during the day, it can also be seen.

But this is just visible light. The X -rays and gamma rays generated in the explosion are high -energy rays that endanger life. If these rays are many and come to the earth at the speed of light, they will cut the life of the earth before the shock wave reaches the reaching. Leek.

Can humans escape this robbery of Sirius supernova?

My answer is definitely possible. But this kind of "capacity" has two meanings. One is that humans have long been extinct and they cannot experience all this. It can also be considered to escape this robbery; and the other is that if humans can continue that day and deal with this kind of kind of like this, this kind of kind of dealing with this kind of like this is to deal with this kind of this kind. The situation has long been a piece of cake.

This premise is that if Sirius wants to burst into a supernova, there will be more than one billion years.

The history of human evolution is only millions of years, the evolutionary history of the Homo sapiens is only 100,000 years, the history of human civilization is only thousands of years, and the history of human science and technology is only hundreds of years. Now, the development of human science and technology has entered the fast track, and it is almost a thousand years in modern times.

If heaven can still give humans for more than 100 million years, scientific and technological civilization has long developed into an unimaginable god -level stage. Either humans have long been on the earth, but have colonized other star systems and even river galaxies. In this way, what kind of moth burst out of Sirius? Is it okay for humans? Therefore, what human beings are worried about now, have reached the bottleneck of survival and development, and whether they can continue. The problem of self -destruction such as environmental and greenhouse effects, nuclear wars, asteroid impact problems, solar drama changes, etc., just like the Damocles sword, is always hung on the done bridge where humans survive. Once it falls, it will continue.

Therefore, the development of science and technology, protecting and restoring the ecological environment, and win -win cooperation are the only way out of human beings. If you want to worry about the outbreak of the supernova, you should be more worried about participating in the fourth. This star has already reached the end of the evolution, and it expands a lot and unstable. Recently, observations have shown that at four o'clock in the stay, it seems that there is an explosion, and maybe it has long been exploded or unknown.

If it was exploded today, we will not be able to see it after 700 years, because this star is about 700 light years from us.

Ginseng Fourth is a star with a mass of 12 times the solar. According to the law of the evolution of the star, the big bang must occur. However, because the distance is too far, the impact of explosion on the earth will not have a great impact. We will only see a star similar to the full moon.

But there is an exception that if gamma rays occur during the explosion, and it happens to be aimed at the earth, we will not be able to eat it. The Optical Period, which occurred 445 million years ago, some studies believe that the result of Gamma rays broke out by the supernova. This supernova was caused by two neutron stars collided, 6000 light years from us.

However, the probability of gamma ray violence, which is not too large like Ginseng Su Si, is very small. Even if it is issued, it may not be just facing the earth.
