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.
This is the end of the starâs life. Stars far larger than our sun, with a higher mass, become increasingly massive and dense as nuclear fusion creates heavier and heavier chemical elements within them, and their gravity increases.
