== Description == R136c is a Wolf–Rayet star of the spectral type WN5h and with a temperature of , making it one of hottest stars known. It is one of the most massive stars known, with a mass of , and it is one of the most luminous stars known, with a luminosity of 3.8 million . The extreme luminosity is produced by the CNO fusion process in its highly compressed hot core. Typical of all Wolf–Rayet stars, R136c has been losing mass by means of a strong stellar wind with speeds over and mass loss rates in excess of solar masses per year.
