'''Stellar evolution''' is the theoretical life cycle of a star. It encompasses all aspects of development to the beginnings of a protostar in a [[nebula]] to the emergence of the star on the main sequence to the final stages of its life as a red giant before it degenerates into a [[white dwarf]], [[neutron star]] or [[black hole]].
