Astronomy Polytrope definition question!

  1. Dec 30, 2008 #1
    1. The problem statement, all variables and given/known data

    Define what is mean by polytrope and polystopic index n. (This is work 2 marks)

    3. The attempt at a solution

    A polytrope is a solution for denstity for the polytropic equation of state.

    Polytropic index is defines as: y = 1 1/n

    So do you think I have defined them properly? How would you do it. I only ask because this seems to come up alot and I would rather get these somewhat easy two marks.
