What is a main sequence star? A star being born It is a medium-sized star It is a star about to die It is a super-large star
OpenStudy (bhcvnjncvjn):
A main sequence star is any star that is fusing hydrogen in its core and has a stable balance of outward pressure from core nuclear fusion and gravitational forces pushing inward.

i think its a star being born
OpenStudy (osprey):
A guess ... Presumably a main seq star is one of medium size (the word "medium" here is an understatement). http://perendis.webs.com
OpenStudy (audiocraft):
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive.
