Brief description This project is to continue timing and profile monitoring of the first
double-pulsar system and two other relativistic binaries discovered in
our surveys. These systems provide unique laboratories for
gravitational physics. In order to exploit them, we had combined
the previous projects P455 & P400 into one request. In addition to the
double pulsar we want to continue our studies of the double neutron
star PSR J1756-2251, and the relativistic binary J1141-6545. We
aim to provide the strongest tests to date for general relativity and
to measure for the first time the moment-of-inertia of a neutron star.
Additionally, we will determine the system geometries and map the
pulsar beams via geodetic precession.
