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 to200 times as massive. Stars start their live...

Main Sequence The main sequence is where a star will spend 90% of its life fusing hydrogen into helium in its core. These type of stars account for around 90% of all stars in the universe, and range in mass from 1/10th to 200 times that of the Sun, with their life spans mostly de...
Pre-Main Sequence Stage These are the stages in the life of the star, which has not yet become a main sequence, one which is fusing hydrogen into helium. There are three pre-stages; generally, all stars will go through these stages. ...
Zero-Age Main Sequence Stars refer to the initial stage in the life cycle of a star, when nuclear reactions first generate its entire luminosity. During this stage, the star's chemical composition is assumed to be spatially homogeneous, and hydrogen is converted to helium at the center. These...
What happens when a main-sequence star exhausts its core hydrogen fuel supply?Stars:Stars are considered to be approximate black bodies that spend most time of their life as a main-sequence star. They have very high pressure and temperature that support the favorable conditions for ...
A main sequence star has characteristics that place it on an H-R diagram's band, or main sequence. Discover features of a main sequence star and why people may have to leave Earth one day. Why We'll Have to Leave Our Planet Over a billion years from now, the Earth's oceans will ...
