Scientific paper

Data related to masses and absolute magnitudes of galactic Wolf-Rayet (WR) stars are compiled to investigate the relationships between WR parameters. The calculated results were used to derive graphs on the M:Mv relation for the WR stars and on the mass loss rate, M(dot), vs Mv and luminosity (L). Applying the bolometric correction (-4.5 + or - 0.2 mag) that was estimated for WR stars to other stars of known M and Mv yielded the M(dot):L relation with a slope of about 0.7 and a spread in M(dot) of an order of magnitude.
