GRASP Routines: Gravitational Radiation from Binary Inspiral

The simplest case is when the two objects are describing a circular orbit about their common center-of-mass, and neither object is spinning about its own axis. With these assumptions the system is then described, at any time, by the masses and of the objects, and their orbital frequency . (It is also necessary to describe the orientation of the orbital plane and the positions of the masses at a given time; these are details we will sort out later).

For convenience in dealing with dimensional quantities, we introduce
the *Solar Mass* and the *Solar Time*
defined by

GRASP functions typically measure masses in units of and times in units of seconds.
