Parkes observations for project P1058 semester 2021OCTS_01

We propose to continue the timing campaign of the new millisecond pulsar, J1431-6328, discovered by the Australian SKA Pathfinder (ASKAP). 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 extremely low mass of the companion and the long orbital period make this binary system unique for the understanding of binary evolution. The stable profile and wide orbit of J1431-6328 also makes it a good candidate for pulsar timing arrays and tests of the strong equivalence principle. Combing one month of high cadence timing with previous regular monitoring, we aim to obtain a coherent timing solution of PSR J1431?6328 and measure its astrometric and orbital parameters with high precision. Results on the timing solution, wide band polarisation properties of this pulsar and studies of the binary system will be published at the end of this semester.
