WebSep 27, 2024 · A main sequence star is any star that has a hot, dense core which fuses hydrogen into helium to produce energy. Most stars in the galaxy are main sequence stars, including Alpha... WebThere are 3 main regions (or evolutionary stages) of the HR diagram: The main sequence stretching from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) dominates the HR diagram. It is here that stars spend about 90% of their lives burning hydrogen into helium in their cores.
