Abstract

Presently the double pulsar allows for the measurement of six post-Keplerian parameters. In addition, its double-line nature gives access to the projected semi-major axes of both orbits. We use this wealth of information to pose some very general restrictions on a wide class of conservative and semi-conservative theories of gravity.
