Spectroscopy of early-type star candidates in M 33 and NGC 6822. II.

CATANZARO G., BIANCHI L., SCUDERI S. and MANCHADO A.

Abstract (from CDS):

We present ground-based spectra of early-type star candidates in the Local Group galaxies M 33 and NGC 6822 taken at the 4.2m William Herschel Telescope (La Palma, Spain). Photospheric parameters Teff and logg were derived by LTE modeling of the Balmer lines. When possible, mass-loss rates were calculated from the Hα profiles computing emission and scattering in the wind with the method of Scuderi et al. (1992ApJ...392..201S). Five hot star candidates were found in M 33, out of seven stars analyzed, and two out of three in NGC 6822.
