Core temperature of stars

  1. Sep 22, 2009 #1
    I'm wondering how realistic it is for a 50 solar mass star to have a core temperature of 3.14*(10^7) K. This isn't much greater than the core temperature of the sun, which is 1.5*(10^7) K. Have I made some huge miscalculation, or does this seem feasible?

    Thanks.

    Core temperature only varies by an order of magnitude in Main Sequence stars - roughly 4 million to 40 million K, from the smallest M to the biggest O star. Remember the reaction rate of the CNO cycle goes up ~(T)17 so only a small rise has a huge effect on a star's output.
