Boyer-linquist Coordinates

  1. Jun 1, 2005 #1
    Hey,
    I was wondering if someone could kindly explain to me everything they can about Boyer-linquist coordinates. I was looking at them and I think I saw something, but I'm not sure. So, someone please tell me everything about them.

    Thanks

    That's a rather vague question. Why do you Kerr about them?

    My, you are a low-down, punning KERR, I think I'll run over you with my KERR.

    And no, I don't know how he pronounced it either.

    You guys do realize that Schwarzchild's solution also utilized the boyer-lindquist coordinates, right?

    Boyer-Lindquist coordinates (r,theta,phi,t) are a generalization of Schwarzschild coordinates (r,theta,phi,t) just as the Kerr solution is a generalization of the Schwarzschild solution.

    See for instance
    http://www.math.ucla.edu/~bon/kerr/intro2.html
    http://scienceworld.wolfram.com/physics/KerrBlackHole.html

    There are some auxillary variables used in the expression for the BL metric
    [tex]\Delta[/tex], [tex]\rho[/tex], however these variables do not appear as differentials in the metric (dr^2, etc.) in the descriptions I've seen (those above plus MTW's Gravitation) so these variables wouldn't qualify as coordinates in my opinion.

    I really don't know what information you are looking for, your questions have been a bit vague so far.
