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.

penguin: Sitting by the river, Dreaming through my reflection, I wonder what has happened. What has caused this distance? We used to be together, Cuddling close to each other. What came between our beautiful love? I don't know, though I wish to. I can see you now, not alone You're holding a hand that's not mine Where am I? Why not next to you? Why am I away? I don't understand. You're smiling to the fullest. I am not the one making you happy. You are glancing at someone else. Why is it not me? Seeing you after such a long time, My heart sighs again. Something inside me growls loud 'Cause now your hand runs through her hair. I stand some distance well away, But the surroundings disappear. When I look at you, I feel lost inside I wish you back, my angel. There you are, holding her hand, And I am lost, trying to understand. I want you back, I really do, Just to hold your hand And walk with you.
