Wolf-Rayet (WR) stars are typically the residual cores of massive stars that had expelled their outer layers when they turned degenerate. They are very hot, extremely luminous, and have minuscule lifespans. In comparison to the Sun, WR-102 is--roughly--sixteen times more massive, half the radius, 380,000 times more luminous, four times as hot, and will have a lifespan only one ten-thousanth that of the Sun. These stars also have a greater presence of heavy elements such as helium, oxygen, or carbon that contribute to their extreme properties.
