    I have a particle on a closed orbit around a star and the mass of the star falls by 1 percent, I have to find the new minimum and maximum orbit distances.

    I got as far as:

    r=-(a/2E)(1+/-(1+(2EL^2/ma^2)^0.5))

    where a=GMm

    many thanks to anyone who can help

    Not conserved as central force changes no?
