Main Sequence Star

(star burning hydrogen into helium)

A Main Sequence Star is a star in the phase of burning Hydrogen (H) into Helium (He), through the Proton-Proton Chain or the CNO Cycle. For many stars, this is the majority of their fusion lifetime, e.g., billions of years for a star such as the Sun.
