Wolf-Rayet star [¦vȯlf rī¦ā ‚stär]

(astronomy)

A member of a class of very hot stars (100,000-35,000 K) which characteristically show broad bright emission lines in their spectra; luminosities are high, probably in the range 10⁴-10⁵times that of the sun; these stars are probably very young and represent an early short-lived stage in stellar evolution.
