Scientific paper

Dimensional analysis is used to obtain an expression for the rate of stellar mass loss depending on mass, radius, and luminosity. A sample of 85 stars with spectral types between O2 and B9, with a range in luminosity of 7000, in mass and radius of about 20, and in rate of mass loss of 700,000, is used. A dimensionless normalizing constant in the derived expression increases as one goes from B to O stars and from O to O(f) to O(f)), but it is not sensitive to luminosity. This indicates that the rate of mass loss may be affected by parameters other than mass, radius, and luminosity.
