WebThe most massive stars will leave the main sequence first, followed in sequence by stars of ever lower masses. The position where stars in the cluster are leaving the main sequence is known as the turnoff point. By knowing the main-sequence lifespan of stars at this point, it becomes possible to estimate the age of the cluster. See also Web30 de dez. de 2024 · The text says that stars spend 90% of their lifetimes in the main-sequence phase of evolution. This suggests that if we have a fair (or representative) sample of stars, 90% of them should be main-sequence stars. Your group should brainstorm why 90% of the brightest stars are not in the main-sequence phase of evolution.

"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. " - On the main sequence massive stars
