Onmar

Onmar is a cataclysmic variable binary star system of the DQ Herculis type. It is the host of a small system of three planets, Gehrels, Khait, and Parchione. It consists of a rare white dwarf pulsar named Ascor and a red dwarf companion named Pagalan, which orbit each other every 6 hours at a separation of 855,000 km. Being the nearest pulsar to Caloris, it has attracted a significant amount of interest from astronomers due to the system's exotic nature.
