I know that the accretion disk of a black hole gets hot enough for powerful emission of x-rays, but does that disk get hot enough for certain elements to fuse?
When the masses of the degenerate electron core inside the two stars come together and exceed a limit, their gravity cannot be supported by degenerate electrons (because the electron energies go relativistic), and the cores collapse into either a neutron star or black hole (either one produces a dense accretion disk if there is enough angular momentum).Irfan Nafi said:But how does the collision of 2 high mass stars result in a black hole?
Yes, fusion can occur in the accretion disk of a black hole under certain conditions. The intense gravitational forces and high temperatures in the disk can cause atoms to collide and fuse together, releasing large amounts of energy.
The elements involved in fusion in the accretion disk of a black hole are primarily hydrogen and helium. These are the most abundant elements in the universe and are found in large quantities in the accretion disk.
The fusion process in the accretion disk releases a significant amount of energy, which is then absorbed by the black hole. This energy contributes to the growth of the black hole and allows it to continue accreting matter from its surroundings.
Yes, there is a limit to the amount of fusion that can occur in the accretion disk of a black hole. This limit is known as the Eddington limit and is determined by the balance between the energy released from fusion and the gravitational force of the black hole.
The fusion process in the accretion disk can have a significant impact on the surrounding environment. The high energy released can heat up the disk and surrounding gas, causing it to emit intense radiation and jets of particles. These processes can also affect the formation of new stars in the vicinity of the black hole.
