The life cycle of stars is contingent on their starting mass. This means that for a star with a small mass their life cycle will begin as a protostar, then the main sequence, then it will become a white dwarf and will die as a black dwarf. For stars with medium mass the same process and stages are applied, however, after the main sequence the star becomes a red giant then a white dwarf. For a star with a large mass, they become a super giant after the main sequence, then end their life cycle as a supernova.
For small stars they will remain hot for a large period of time as their is a small surface area. They can shine for billions of years before their fuel runs out. Stars with small masses are the most common stars.
Some stars can start another cycle of nuclear reactions if they are massive enough.
