Homework Help: Is it possible - Stefan Boltzman Law

  1. May 16, 2007 #1
    I have an intensity graph versus wavelenght of the light emited by two stars.

    For one of stars the curve of the graph temperature is 12000 K; for the other 3000 K.
    Is it possible, only from this data, to know wich star will die first?

    Thanks
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    three relationsship in basic stellar astrophysics:

    1. (effective) temperature - Bolometric Luminosity

    2. Lumonosity - mass

    3. Mass - lifetime
