Parkes observations for project P455 semester 2019APRS_08
This project is to continue timing and profile studies of the first double-pulsar system, a unique laboratory for gravitational physics. Recent results, including the first measurements of higher-order light-propagation effects and of the relativistic deformation of the orbit, highlight the importance of a long term observational campaign for this ... moreremarkable system. The main aims of this proposal are 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 geometry and map the pulsar beams via geodetic precession. Whenever possible, we will exploit the high sensitivity of the new UWL receiver. less

P455 - Timing & geodetic precession in the double pulsar and two
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 puls... morear 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. less
