How do the stars that fall into the clutches of the black hole end? Answering this question is difficult, but scientists already understand the process a little better, thanks to several new simulations.
In the new research, the team of astrophysicists used a simulation in which they created several other different stars, fired to meet black holes and then watched what would happen, the portal wrote. Science alert. The researchers say their study is the first of its kind. They combined Einstein’s theory of relativity with a realistic model of the density of main-sequence stars.
The results of the work aim to clarify what actually happens to scientists when they spot flashes of light in distant regions – the star’s last moments before a black hole rips it to shreds. The generated simulations also support the study from last year. If you are interested in what happens in such a situationYou can watch the simulation in the video below.
When the star approaches Black hole Nothing nice awaits her. It is subjected to an intense gravitational force, which begins to deform the star and eventually rips it to shreds. These forces are also referred to as tides and Describe the deformation of a cosmic body due to the gravitational force of another body.
A star approaching a black hole loses its matter – it is forcibly torn from it. This is called a tidal break. In a worst-case scenario, the star cannot escape the grip of the black hole. tidal forces They strip away some of the material that extends over the spaghetti and ends up in the bowels of a black hole.
But not every meeting ends tragically. Simulations have also shown that some stars can survive a black hole encounter. Their goal was to find out what factors contribute to a star’s survival.
Six black holes were waiting for the glowing objects in the simulation. These ranged in weight from 100,000 to 50 million solar masses. Each black hole subsequently met the eight main succession stars. Its mass ranged between 0.15 and 10 times the mass of the Sun.
The results showed that the main factor in the survival of the star is the original density of the star. The denser the star, the more likely it is to survive a collision with a black hole. At the same time, it turns out that a partial interruption of the tides is as likely as the total. Scientists can easily express what percentage of mass a star would lose.
But the team of scientists has not finished their work. Future research will focus on the small details that may play a role in the fatal clash. But they will also focus on what happens to the star that survives the encounter with the black hole. Scientists wonder if the star will still follow the main sequence, or if it will become a remnant of the star.
The question also remains whether the star who survived the initial encounter It will remain in orbit and its fate will be determined at a later time.
