High Energy Emission from the Double Pulsar system J0737-3039

Astrophysics 2009-11-10 v2

Abstract

We discuss the effects of particle acceleration at the bow shocks expected in the binary pulsar system J0737-3039, due to the wind from pulsar A interacting with both the interstellar medium (ISM), and with the magnetosphere of pulsar B. In this model, we find that the likeliest source for the X-rays observed by Chandra is the emission from the shocked wind of pulsar A as it interacts with the ISM. In this case, for favorable model parameter values, better statistics might help Chandra marginally resolve the source. A consequence of the model is a power law high energy spectrum extending up to \lesssim 60 keV, at a level of 2×1013\sim 2 \times 10^{-13} erg cm2^{-2} s1^{-1}.
