Main Sequence Star

(Dwarf Star)
(star burning hydrogen into helium)

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

The term Dwarf Star actually refers to any star that is not a Giant Star, basically a main sequence star (though White Dwarves might be meant as well).
