Wolf-Rayet galaxies

Wolf–Rayet galaxies

(wûlf ray -ĕt; volf rah-yay ) A rare type of starburst galaxy, whose spectra contain emission features that reveal the presence of hundreds to thousands of Wolf-Rayet stars. Wolf-Rayet galaxies also show other indicators of massive stars, such as a blue continuum and emission-lines typical of H II regions.

Somewhat similar are the Wolf-Rayet galaxies, which instead have unusually large populations of Wolf-Rayet stars.
