Monte-Carlo simulations of linear polarization in clumpy OB-star winds
Abstract
We present results from Monte-Carlo simulations of linear polarization in clumped OB-star winds. We find that previous single-scattering models of clumped winds have overestimated the degree of polarization, even in cases where individual clumps are optically thin. An application to P Cygni suggests the star's wind is more fragmented than previously thought.
