See WR 138a and Terminal velocity
Wolf–Rayet star
Wolf–Rayet stars, often abbreviated as WR stars, are a rare heterogeneous set of stars with unusual spectra showing prominent broad emission lines of ionised helium and highly ionised nitrogen or carbon. WR 138a and Wolf–Rayet star are Wolf–Rayet stars.
