The Influence of the Ratio of Total to Selective Extinction on the Determination of the Mass Loss Rate of Wolf Rayet Stars from Infrared Excess Measurements
It is shown that the mass loss rate of the WN7 star HD 93162 decreases with larger values of the ratio of total to selective extinction R. For HD 93162 the mass loss rate will change one order of magnitude, only if ΔR ~ 2. Mass loss rates are derived for nine other WR stars of which visual, red and near-infrared photometric observations were obtained.
