Parkes observations for project P1038 semester 2020APRS_03
PSR~J1759-2402 is one of a small handful of pulsars which are in orbit about high mass stars. Its orbital period is 8.2 years and the orbit is highly eccentric with periastron expected in 2021 January. Although discovered at Parkes, the Lovell telescope has been monitoring the pulsar over many years. However, it's restricted bandwidth and lack of p... moreolarization capability make it unsuitable to follow the pulsar as it enters and leaves the eclipse by the companion. In contrast, the UWL on Parkes with its wide-band and excellent polarization characteristics means that we can determine scattering, polarization, dispersion measure and rotation measure changes as the pulsar enters its companion wind. We request weekly observations of the pulsar to track its progress around the orbit. less

P1038 - Wide-band observations of PSR J1759-2402 through periastron
Radio pulsars are awesome stars. Smaller than a city, they weigh more than the Sun. We want to look at one particular pulsar which is in orbit around a star 8 times more massive than the sun. It only orbits once every 8 years and we're expecting fireworks to happen when the pulsar comes near its companion. The new fandabby receiver on the Parkes te... morelescope is the best in the world to figure out what the pulsar is doing and what the companion star is made of. less
