watch eight stars come out to
Observe eight models of stars expanding and deforming as they approach a hypothetical black hole a million times the mass of the Sun. The black hole turns some stars into a stream of gas, a phenomenon called a tidal perturbation event. Others managed to resist their intimate encounters. These simulations show that destruction and survival depend on the initial density of stars. Yellow represents the highest intensity, while blue represents the lowest intensity. attributed to him:
This simulation, led by Taihu Ryu, a member of the Max Planck Institute for Astrophysics in Garching, Germany, is the first to combine the physical effects of Einstein’s general theory of relativity with realistic models of stellar density. The mass of hypothetical stars varies from about one-tenth to 10 times the mass of the Sun.
The division between stars that explode completely and those that last is not about mass. Instead, survival depends more on the star’s density.

The star expands and loses some of its mass, then begins to regain its shape as it moves away from the black hole. Credit: NASA’s Goddard Space Flight Center / Taiho Rio (MPA)

Rio and his team also investigated how other properties, such as the masses of different black holes and stellar proximity, affect tidal perturbation events. The results will help astronomers estimate how often high tide disturbances occur in the universe and help them build more accurate images of these tragic cosmic events.
