WebSep 26, 2024 · The basic definition of a 'giant' star is one that is more luminous than a main sequence star. As the name suggests, part of the reason for this is simply that such stars are enormous in size. WebThis table shows that the most massive stars spend only a few million years on the main sequence. A star of 1 solar mass remains there for roughly 10 billion years, while a star of about 0.4 solar mass has a main-sequence lifetime of some 200 billion years, which is longer than the current age of the universe.

WebWe find that these galaxies are generally heavily dust-obscured (A V ~ 2 mag), massive (log (M/M ⊙) ~ 10), star-forming sources at z ~ 2 - 8 with an observed surface density of ~0.8 arcmin-2. This suggests that an important fraction of massive galaxies may have been missing from our cosmic census at z > 3 all the way into the Reionization epoch. WebA protostar becomes a main sequence star when its core temperature exceeds 10 million K. This is the temperature needed for hydrogen fusion to operate efficiently. The length of time all of this takes depends on the mass of the star. The more massive the star, the faster everything happens.
