Binary pulsars PSR B1913+16
« on: 10/08/2013 15:30:58 »
I have been looking at the observation data on the subject pulsars. Say, the data on the orbit of one pulsar -- is it relative to the other pulsar or to the center of mass? Depending on the answer, I have another question. Thanks.

It depends on what data you're referring to. Normally orbits are given in terms of the  semimajor axis of the ellipse that they're moving in. That's relative to the other body, not the center of mass.

Thank you, Pmb.
That what I understand: derive equations for Body-1 with respect to Body-2. But then, the rate of change in semimajor axis and orbital period of Body-1 are relative to Body-2. I don't think these are the observed magnitudes! Do they need to be converted to the CM?
