Brief description

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 relatively low mass of the companion and the long orbital period make this binary system extremely interesting 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. By the end of this semester, we plan to summarise the timing campaign with a paper and publish the timing solution, wide band polarisation properties of this pulsar and studies of the binary system.
