WebA neutron star is an even smaller, hotter star, where the atoms have collapsed to form a core made of closely-packed neutrons. Like a white dwarf, there is no longer any fusion happening. WebStar formation happens in interstellar molecular clouds: opaque clumps of very cold gas and dust. The process starts when some of those clumps reach a critical mass, allowing them to collapse under their own gravity.
