WebThe lifetimes of main sequence stars therefore range from a million years for a 40 solar mass O-type star, to 560 billion years for a 0.2 solar mass M-type star. Given that the Universe is only 13.7 billion years old, these long main sequence lifetimes for M-type stars mean that every M star that has ever been created is still on the main sequence! WebL ≈ M n where the exponent varies a bit for stars of different masses, but, in general, is approximately equal to 3.5, as is seen to be the case with the observed masses and luminosities for stars in binary systems. imt newport colony apartments https://treyjewell.com
