How black hole form
WebBlack holes can be surrounded by rings of gas and dust, called accretion disks, that emit light across many wavelengths, including X-rays. A supermassive black hole’s intense … WebAstronomers generally divide black holes into three categories according to their mass: stellar-mass, supermassive, and intermediate-mass. The mass ranges that define each group are approximate, and scientists are always reassessing where the boundaries should be set. Cosmologists suspect a fourth type, primordial black holes formed during the …

If the core is massive enough, then the neutron star will be too massive to be supported by any source of pressure and would quickly collapse to a black hole. This might be very likely if the supernova is ...
