Homework Help: Stellar Ionisation

  1. Aug 12, 2017 #1
    1. The problem statement, all variables and given/known data
    Hi, I am studying for a test on Monday and I was wondering if someone could clarify something in my notes on the ionisation rate of Type O stars. The line in my notes says;

    L = 105L0 ⇒ S* ~ 105 /13.6eV ⇒ S* ~ 1049

    Basically, I don't have an actual formula for S* and I was hoping someone could tell me if there is one and/or why it seems to be the luminosity over the ionisation energy?

    Thanks for any help!

    2. Relevant equations

    3. The attempt at a solution
    I know 13.6eV is the ionisation energy for H(n=1)

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
