In common with other early-type stars, epsilon Ori (B0 Ia) shows evidence for structure in its stellar wind. Variations in optical and ultraviolet line profiles reveal the presence of large-scale structure in the inner wind. The detection of X-rays …
We investigate stochastic structure in hot-star winds. The structure (i.e. inhomogeneities such as clumps and shocks) is generated by the instability of the line driving mechanism in the inner wind. It is self-excited in the sense that it persists …
Time-dependent hydrodynamical models predict that the stellar winds of early-type stars are clumped, due to the sweeping up of material into dense shells. In this paper we investigate whether these shells can explain the long wavelength (=10 micron) …
The infrared and radio continuum fluxes of 18 well-observed early-type stars are studied by comparing observations with theoretical models. The observations are taken from the literature. All available observations are included. The theoretical NLTE …
The infrared and radio continuum fluxes of a number of OB-stars are compared to theoretical models. This gives us information about the mass loss rates and the structure of the stellar wind. The more extreme O-star zeta Pup appears to show an effect …
