The stars are staring at death

They are located deep in the center of the Milky Way and move around the black hole, the space is capable of destroying all kinds of matter in the universe, including light.

Astronomers have long wanted to know why giant stars can exist alongside black holes in the middle of our galaxy. Their formation process is not the same as ordinary stars - that is, created by a cloud of dust and gas - because this cloud is definitely torn under the impact of terrifying gravitational force from the hole. black nearby.

Some scientists argue that stars are formed outside the center of the galaxy and then move along the spiral into the center. However, no evidence has been found to prove this hypothesis.

Now two Scottish astronomers have built a model to explain the formation of giant stars in a deadly space near a black hole.

According to Ian Bonnell's model of St Andrew and William Ken Rice University of Edinburgh University, a huge cloud of dust and gas is drawn towards the black hole. As it approached, most of the cloud was torn into pieces by the gravitational pull of the black hole. But part of it "escapes" thanks to the chaotic movement of air masses. The remainder forms an oval disk of dust gas that moves around the black hole.

Although moving near a black hole, the gas disk is not sucked into the hole because it is within a safe range. The changes in material density inside the gas disk make it thicken over time, eventually breaking and forming stars. These stars continue to move in oval orbits that the gas disk leaves behind.

Scientists also want to find out if the process occurs in other galaxies' black holes. Studying the center of other galaxies is unbelievable because they are too far away, but Ian Bonnell and William Ken Rice argue that their model can be applied to the whole universe.
