Astronomy Lesson 04_08: Stellar Mass, Luminosity and Lifespan
Now we get to some real meat of astrophysics. We discuss the relationship between mass, luminosity and lifespan of main sqeuence stars. It is an amazing discovery that mass is known to be tictly correlated to luminosity for M-S star. And for M-S stars, the luminosity is tightly related to spectral type. So, just get the spectrum, and you know the mass!
