PSR J1302−6350 is a pulsar and member of an eclipsing binary star system with the blue O9.5Ve-class star LS 2883. The pair has an eccentric orbit that is inclined to the line of sight from Earth by about 36°, leading to a 40-day-long eclipse each time the pulsar passes behind the star.[4] The pulsar has a period of about 48 ms and a luminosity of 8.3 × 1035 erg/s. It emits very high energy gamma rays that vary on a time scale of several days.[6]
The star LS 2883 has about 10 solar masses and is 6 solar radii in size. The rate of rotation is about 280 km/s at the equator, or 70% of the breakup velocity.[4]
