R136a1: Properties, Discovery & Evolution

R136a1 (short for RMC 136a1) is the most massive and luminous star known, at around 291 solar masses (M☉) and around 7.2 million times the Sun's luminosity (L☉). It is a Wolf–Rayet star at the center of R136, the central concentration of stars of the large NGC 2070 open cluster in the Tarantula Nebula (30 Doradus) in the Large Magellanic Cloud. The…
