Stellar Population in Milky Way

  1. Feb 26, 2007 #1
    Hey folks,

    I'm currently at grad school and am working on an algorithm to try and model the rate of supernova (type I and II) in our galaxy.

    I really need to know the following information.

    1) Where can I find information on HOW MANY of the different types of stars there are in our galaxy. E.g, how many red giants, how many massive red giants. ( I just need rough numbers).

    2) Is there any information on there (rough) location. i.e Are some stars likely to be located closer to the center of the galaxy than others.

    I've done quite an extensive google search but don't seem to find the info I'm looking for.

    Any help would be greatly appreciated.

    I am hoping Space Tiger, Garth, Cronos or others will pop in here, but here is a start or at least an attempt -

    See if one can find this paper or contact the author -
