Observational constraints on the efficiency of acceleration in the optically thin parts of Wolf-Rayet winds
نویسنده
چکیده
Wolf-Rayet stars have such strong winds that their inner regions are optically thick, preventing us from seeing the hydrostatic stellar cores. One might expect considerable acceleration of the wind to occur in the optically thick part. However, we show empirically that at least 50%, and in some cases up to 100%, of the wind’s acceleration occurs in the optically thin part of the WR wind.

An explanation for the curious mass loss history of massive stars: from OB stars, through Luminous Blue Variables to Wolf-Rayet stars
The stellar winds of massive stars show large changes in mass-loss rates and terminal velocities during their evolution from O-star through the Luminous Blue Variable phase to the Wolf-Rayet phase. The luminosity remains approximately unchanged during these phases. These large changes in wind properties are explained in the context of the radiation driven wind theory, of which we consider four ...
متن کاملModels of Forbidden Line Emission Profiles from Axisymmetric Stellar Winds
A number of strong infrared forbidden lines have been observed in several evolved Wolf-Rayet star winds, and these are important for deriving metal abundances and testing stellar evolution models. In addition, because these optically thin lines form at large radius in the wind, their resolved profiles carry an imprint of the asymptotic structure of the wind flow. This work presents model forbid...
متن کاملMetallicity Dependent Wolf-Rayet Winds
Observational and theoretical evidence in support of metallicity dependent winds for Wolf-Rayet stars is considered. Well known differences in Wolf-Rayet subtype distributions in the Milky Way, LMC and SMC may be attributed to the sensitivity of subtypes to wind density. Implications for Wolf-Rayet stars at low metallicity include a hardening of ionizing flux distributions, an increased WR popu...
متن کاملWolf-Rayet stars probed by AMBER/VLTI
Massive stars deeply influence their surroundings by their luminosity and the injection of kinetic energy. So far, they have mostly been studied with spatially unresolved observations, although evidence of geometrical complexity of their wind are numerous. Interferometry can provide spatially resolved observations of massive stars and their immediate vicinity. Specific geometries (disks, jets, ...
متن کاملAn explanation of observed trends in the X - ray emission from single Wolf - Rayet stars
The O and early B star winds show empirical correlations between X-ray (L x) and Bolometric (L Bol) luminosity as well as wind properties such as wind momentum and wind kinetic energy. Wolf-Rayet stars do not. We discuss scaling relations to qualitatively explain this lack of correlation among the WR winds and to quantitatively reproduce the observed ratio of X-ray luminosities between the N-ri...
