What is another word for main sequence star?
Pronunciation: [mˈe͡ɪn sˈiːkwəns stˈɑː] (IPA) 
A main sequence star is a type of star that is in the phase of its life cycle where it is burning hydrogen at its core. This is the longest stage of a star's life, where it is stable and produces energy through fusion reactions. There are several synonyms for the main sequence star, including dwarf star, yellow dwarf star, and G-type star. These stars are similar in size and spectral classification, and they are often referred to as "normal stars." Main sequence stars are important because they serve as a reference point for the study of other stars, and they provide the energy that allows life to exist on Earth.
