Homework Help: Supernova explosion n angular momentum

  1. Sep 13, 2005 #1
    a planet moves around a star. (mass of planet << mass of star). the star undergoes a supernova explosion and loses 20% of its mass. the explosion does not directly affect the motion of the plant at that instant. how would this change the angular momentum of the planet ant the shape of its orbit. what would happen if it was in a circular orbit? what would happen if it was in an elliptical orbit?
