[PAR] [TLE] WR 102c [SEP] WR 102c is a Wolf–Rayet star located in the constellation Sagittarius towards the galactic centre.  It is only a few parsecs from the Quintuplet Cluster, within the Sickle Nebula. [PAR] [TLE] Wolf–Rayet star [SEP] Wolf–Rayet stars, often abbreviated as WR stars, are a rare heterogeneous set of stars with unusual spectra showing prominent broad emission lines of highly ionised helium and nitrogen or carbon.  The spectra indicate very high surface enhancement of heavy elements, depletion of hydrogen, and strong stellar winds.  Their surface temperatures range from 30,000 K to around 200,000 K, hotter than almost all other stars.
