Brief description

We propose to carry out a Parkes timing campaign of the new millisecond pulsar, J1431-6328, discovered by the Australian SKA Pathfinder (ASKAP) and Parkes Ultra-Wideband Low (UWL) receiver. PSR J1431-6328 has a spin period of 2.77 ms and is in a very wide binary system with an orbital period of 88 days. The relatively low mass of the companion and the long orbital period make this binary system extremely interesting for the understanding of binary evolution. The wide orbit of J1431-6328 also makes it useful for tests of the strong equivalence principle. The proposed program will allow us to better measure its binary parameters and to achieve more precise localisation of the pulsar, which is crucial for the optical follow-up of the system.
