Spectral Analyses of Wolf-Rayet Stars: The Impact of Clumping
Published online by Cambridge University Press: 12 April 2016
Abstract
Inhomogeneities are accounted for in our non-LTE stellar wind models in a first-order approximation. When applied for spectral analyses, clumpy models yield lower mass-loss rates than homogeneous models, while other parameters are not affected. For representative WR stars, we determine the density contrast from the electron-scattering line wings and obtain mass-loss rate reductions by a factor of two, typically.
