Virial theorem

  1. Dec 26, 2012 #1
    Hello,

    I am reading Virial theorem from Wikipedia.

    It states in astrophysics, virial relations are:

    3/5 GM/R=3/2.....

    I want to know how this 3/5 and 3/2 value comes from?

    If somebody can explain the step by step deduction of the Virial theorem in Astrophysics......

    Thanks,

    Why not look it up yourself? The book Galaxy Formation by Malcom S. Longair has a derivation in section 3.5.1 (page 63). Actually, you can even read this section as part of the Google Books preview:

    I also seem to recall that Caroll & Ostlie (the huge orange textbook that many undergrads majoring in astro use) has a section on this as well.
