Astronomers have found that it takes two stars to make gamma rays, According to research, the largest and brightest explosion that can be seen in the universe requires two stars to trigger gamma rays.
A new study solves the mystery of how the star spins fast enough to create conditions for firing high-energy rays into space and finds that tides like the flow between the moon and the earth are the answer. This discovery was made using a simulation model of thousands of binary star systems, namely the solar system that has two orbiting stars. Now the Astronomers have found that it takes two stars to make gamma rays.
More than half of all stars are in the binary system, and this new study shows that they must be in a binary system to produce a large explosion.
A long gamma ray burst (GRB), the type studied in this study, occurs when a massive star, about ten times larger than our Sun, turns into a supernova, hits a neutron star or black hole, and shoots a relativistic star in a room. Instead of dropping the star radially inward, the star is flattened to the disc to maintain angular inertia.
When material falls in, this angular momentum fires in a beam along the polar axis.
However, to form this material flow, the star must spin fast enough to fire material along its axis. This is a problem because stars usually lose every spin they win very quickly.
By modeling the behavior of these massive stars when they collapse, researchers can limit the factors that lead to jet formation. They found that the effects of neighboring tides, the same effect that the moon and earth had when they rotated, could be responsible for causing these stars to rotate at the speed needed to produce gamma rays. is.
Gamma ray bursts are the most sacred events in the universe and are observed from Earth when the material rays are directed directly at us. That means we only see about 10-20% of GRB in our sky.
The question is how the star starts to spin or continues to rotate with time. We have found that the tidal effects of stars on their partners stop slowing their pace and in some cases rotating them.
They steal rotational energy from their friends, which means they move further. We have found that most stars spin rapidly because they are in a binary system. Using a technique called binary population synthesis, scientists have been able to simulate this mechanism in populations of thousands of star systems, identifying rare cases where such explosions can occur.
There is also a major dilemma regarding the authenticity of stars which produces bursts of gamma rays. As astronomers, we measure star composition, and the path that applies to gamma ray bursts requires very few iron atoms or other heavy elements in the star’s atmosphere.
There is mystery why we see different compositions in stars that produce gamma rays, and this model offers an explanation. With this model, we can predict what the surveillance system will look like in terms of temperature and luminosity and which satellite properties are possible. We are now interested in using this analysis to investigate various astrophysical transients such as rapid radio radiation and to model events that may be less common such as black holes marked with stars.
