Astronomers from the University of Warwick have created a computer model of the evolution of the solar system at the final stage of the existence of our star.
The researchers involved in the model of Planet X, whose existence was theoretically proved this spring. As a result, according to scientists, it was found that 7 billion years after the Sun will pass red giant phase, during which absorb next to it the planet and “uzhmetsya” to a white dwarf, the planet X will throw out into interstellar space are two other planets -. Neptune and Uranus
The solar system may be destroyed by the actions of the ninth planet, if that really exists. Such a conclusion was a physicist Dimitri Veras from the University of Warwick, published article in the scientific MNRAS magazine.
Predicting the ninth planet was a sensation in January of this year , after publication of an article astronomers Batygina Constantine and Mike Brown. In it, they pointed out that the observed deviations in the movements of a number of bodies in the Kuiper Belt can only be explained by the presence on the outskirts of the solar system the ninth,
have not yet found a planet, 10 times heavier than the Earth.
The prediction has become an event in the scientific world, many scientists began to look for the invisible planet and joined the calculations of its orbit. Calculations Veras show that the presence of the ninth planet could throw out of the solar system at least one giant planet, and it will happen after the sun itself death.
According to the accepted ideas about the evolution of stars, a few billion years, the sun’s outer shell will begin to expand and the core, on the contrary – to contract, to then turn into a white dwarf. During this process, it absorbs the sun inner planets, including the earth, thus to lose half of its own weight. This should make the rest of the planets – Jupiter, Saturn, Uranus and Neptune – to move away from the sun at a safe distance, but such a scenario is possible only with the well-known today configuration of planets
Veras calculated that the presence of the ninth planet will not. realized this peaceful scenario. Calculations have shown that the expansion of the Sun ninth planet not behave like the giant planets, but on the contrary, closer, starting to circle them in the
«deadly dance.” The most likely scenario in this case would be vyshvyrivanie these planets in interstellar space.
Using a unique code that allows you to simulate the destruction of a variety of planetary systems, the scientist counted developments depending on the distance of the orbit of the mysterious ninth planet. It turned out that the more and more massive the planet, the more dramatic will be the end of the solar system
Veras said the potential danger that can create the ninth planet, the Earth will no longer exist:. “The existence of distant massive planet can dramatically change the fate of the solar system. Its fate will depend on the mass and orbital properties of the ninth planet, if it exists. »
The fact that today astronomers observe on the surface of many white dwarfs, remnants of solid planets indirectly indicates that such a scenario is very likely. “The future of the Sun can be predicted by looking at white dwarfs,” contaminated “solid debris.
The ninth planet may act as a catalyst for such pollution.
What will happen with the sun on the white dwarf stage, can be seen today in the white dwarfs around the Milky Way, “- said the author of
However, while the existence of Planet X has not received acknowledgments. The existence of such a planet can say “Kuiper failure” – the asteroid belt, which ends abruptly at a distance of 48 astronomical units from the sun. Some astronomers believe that such a break can talk about the existence of the order of 60 and a distance. ie an object with a mass similar to Earth or Mars mass:. it is assumed that the asteroids that fall in the field of attraction of the planet, were taken out of the Kuiper belt, leaving the
«failure»
Others, however, do not believe it. consideration is the basis for the extension of the existence of the hypotheses of Planet X.
