Main sequence lifetime is the phase in which a star is burning hydrogen in its core. The lifetime of a star is determined by its mass, and for a star like the sun (which has a mass of about 1 solar mass), its main sequence lifetime is about 10 billion years. After this phase, it will evolve into a red giant and eventually become a white dwarf.
