Homework Statement



Two individual stars in a binary system (m1=mo, m2=2mo) are in circular orbit about their common centre of mass and are separated by a distance ro. At some stage, the more massive star explodes - resulting in the two stars having equal mass after the explosion

(a)Calculate the total energy, angular momentum and period of the binary star as viewed in the ZMF before the collision.

Homework Equations





The Attempt at a Solution



Not sure how to do this...For energy, do I find the energy of each inidividually and add? How about for angular momentum? Surely that is just zero in total because the two are equal and opposite?
thanks
