When the stars go out. Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence.Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs.White dwarfs no longer burn fusion at their center, but they still radiate heat.ventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence. Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs. White dwarfs no longer burn fusion at their center, but they still radiate heat.
Other kinds of dwarf stars result from the further evolution of main-sequence stars not massive enough to become neutron stars or black holes (which form from the burned-out core of a supernova). The type known as a white dwarf is the remnant of a red giant star that has burned nearly all its fuel.
