| Abstract | While 21 W-R star candidates have been found in about two-thirds of the giant Sb galaxy M31 by a search to continuum magnitude of B value approximately 21.5, no candidates have been found in the irregular galaxy NGC 6822. Subsequent spectrophotometry has revealed that 17 of the 21 candidates are W-R. While the number of detected W-R stars is low, it is compatible with the total number of luminous and massive stars in each galaxy. In M31, most of the W-R stars lie in the ring of prominent star formation 7-12 kpc from the center. The variation of W-R subclasses with galactocentric distance implies a metallicity gradient similar to that in the Galaxy. |
