PSR J2322-2650 -- A low-luminosity millisecond pulsar with a planetary-mass companion

We present the discovery of a binary millisecond pulsar (MSP), PSR J2322-2650, found in the Southern section of the High Time Resolution Universe survey. This system contains a 3.5-ms pulsar with a \sim10^{-3} M_{\odot} companion in a 7.75-hour circular orbit. Follow-up observations at the Parkes and Lovell telescopes have led... Show more
