V921 Scorpii b is a candidate 60-Jupiter-mass brown dwarf orbiting V921 Scorpii, a 20-solar-mass 30,000 K Herbig Haro B0IV-class subgiant. The object is 835 AU away from V921 Scorpii. Despite the large distance, V921 Scorpii b receives a comparable amount of irradiation as Mars, owing to the large mass and luminosity of V921 Scorpii.[1]
While this candidate object is likely a brown dwarf, it is included in the Extrasolar Planets Encyclopaedia since it includes substellar objects with masses up to 60 Jupiter masses.[1]
Host star
[edit]With 20 solar masses in mass and 30,000 K in temperature, V921 Scorpii is a Herbig Haro B0IV-class subgiant and the most massive star to host a substellar object.[1]
