We present radio and submillimetre observations of the O4I(n)f star zeta Pup, and discuss structure in the outer region of its wind ( ~ 10-100 R_*). The properties of bremsstrahlung, the dominant emission process at these wavelengths, make it …
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 …
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 …
