LP 40-365 explained
LP 40-365 is a low-mass white dwarf star in the constellation Ursa Minor. It travels at high speed through the Milky Way and has a very unusual elemental composition, lacking hydrogen, helium or carbon. It may have been produced in a subluminous Type Iax supernova that failed to destroy its host star totally.[1] [2] [3] The "LP" name is derived from the Luyten-Palomar proper motion catalogue in which it appeared in the 1960s.[4] Another catalog name for this star is "GD 492".[5] The star was cataloged as a Giclas object with the designation "GD 492" being assigned by Henry Giclas in 1970.[6]
