The meaning of MAIN SEQUENCE is the group of stars that on a graph of spectrum versus luminosity forms a band comprising 90 percent of stellar types and that includes stars representative of the stages a normal star passes through during the majority of
How long a main sequence star lives depends on how massive it is. A higher-mass star may have more material, but it burns through it faster due to higher core temperatures caused by greater gravitational forces. While the sun will spend about 10 billion years on the main sequence, a star...

The pressure and temperature of a main sequence star increase as you get closer to its center. The length of time that a star spends at this stage in its life depends on how much mass the star has. Counterintuitively, massive stars have a shorter lifespan than smaller stars. Large, ...
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 ...

An F-type main-sequence star (F V) is a main-sequence, hydrogen-fusing star of spectral type F and luminosity class V. These stars have from 1.0 to 1.4 times the mass of the Sun and surface temperatures between 6,000 and 7,600 K.[2]Tables VII and VIII. This temperature range gives...

It is suspected of harbouring a large population of pre-main-sequence (PMS) stars. Aims: We have probed the stellar population of NGC 1893 in an attempt to determine its size and extent. In particular, we look for signs of sequential star formation. Methods: We classify a large sample ...
