Parkes observations for project P1027 semester 2019OCTS_12

Full description

We propose to carry out Parkes follow-up observations of the new millisecond pulsar, J1431-6328, discovered by the Australian SKA Pathfinder (ASKAP) and Parkes Ultra-Wideband Low (UWL) receiver. The discovery demonstrated the power of identifying pulsar candidates in radio continuum images and then following up with high time resolution observations. The discovery itself is also interesting. PSR J1431-6328 has a spin period of 2.77 ms, and is likely to be in a binary system. Follow-up observations will enable us to measure the binary parameters, which will guide future multi-wavelength observations and might shed new lights on the binary evolution. The short spin period, relatively large flux density and sky location of PSR J1431-6328 also make it a promising candidate for pulsar timing arrays. The proposed observations will allow us to obtain a timing solution of this new pulsar, and are therefore essential for future timing observations.
