Explanation:
Detailed explanation-1: -The Wolf-Rayet star WR 102 is the hottest star known, at 210, 000 K.
Detailed explanation-2: -Only the hot core of the star remains. This core becomes a very hot white dwarf, with a temperature exceeding 100, 000 Kelvin. Unless it is accreting matter from a nearby star (see Cataclysmic Variables), the white dwarf cools down over the next billion years or so.
Detailed explanation-3: -The hottest stars are blue, with their surface temperatures falling anywhere between 10, 000 K and 50, 000 K. Stars are fuelled by the nuclear fusion reactions at their core.
