Abstract

The double-pulsar J0737-3039 is not only the most promising system for testing general relativity, but appears a unique laboratory for investigating the so far unaccessible pulsar magnetosphere and the mechanism for radio emission. In fact, the very high orbital inclination gives the possibility of using the radio beams from pulsar A as a probe for investigating the region close to the surface of pulsar B, while relativistic effects modify the system geometry in a timescale suitable for comparing predictions of various models with observation. We present the status of the multi-wavelength observations performed in the 3 years since the discovery and discuss short and long term perspectives for the study of the magnetosphere of pulsar B.
