What places a limit on the lifetime of a star?
A) Loss of the mass,and therefore of nuclear fuel,of the star into space by stellar winds
B) Amount of available nuclear fuel it contains
C) Collisions between stars in a galaxy that are sufficiently frequent for all stars to eventually be destroyed in this way
D) Buildup of spin as it evolves and contracts,causing it to eventually spin apart

Question

Quizplus · Accepted Answer

The lifetime of a star is primarily determined by the amount of nuclear fuel it contains. Once a star has exhausted all of its available fuel, it will enter the final stages of its life and either explode as a supernova or collapse into a compact object such as a white dwarf, neutron star, or black hole. Loss of mass due to stellar winds can also contribute to a shorter lifespan, but it is a secondary factor. Collisions between stars in a galaxy and buildup of spin are not significant factors in limiting the lifetime of a star.
