Mass loss predictions for Subdwarf B stars
We present the results of Monte Carlo mass-loss computations for hot low-mass stars, specifically for Subdwarf B (SdB) stars. It is shown that the massloss rates on the Horizontal Branch (HB) computed from radiative line-driven wind models are not high enough to create SdB stars. We argue, however, that mass loss plays a role in the chemical abundance patterns observed both in field SdB stars, ...
متن کاملNew theoretical mass-loss rates of O and B stars
We have calculated mass-loss rates for a grid of wind models covering a wide range of stellar parameters and have derived a mass-loss recipe for two ranges of effective temperature at either side of the bi-stability jump around spectral type B1. For a large sample of O stars, it is shown that there is now good agreement between these new theoretical massloss rates that take multiple scattering ...
متن کاملMass loss from OB-stars
We review recent developments regarding radiation driven mass loss from OB-stars. We first summarize the fundamental theoretical predictions, and then compare these to observational results (including the VLT-FLAMES survey of massive stars). Especially we focus on the mass loss-metallicity dependence and on the so-called bi-stability jump. Subsequently we concentrate on two urgent problems, wea...
متن کاملOn the reliability of mass-loss-rate estimates for AGB stars
Context. In the recent literature there has been some doubt as to the reliability of CO multi-transitional line observations as a massloss-rate estimator for AGB stars. Aims. Using new well calibrated CO radio line observations, the main aim of the work presented here is to carefully evaluate the reliability of CO mass-loss-rate estimates for intermediateto high-mass-loss-rate AGB stars with di...
متن کاملThe Discordance of Mass-Loss Estimates for Galactic O-Type Stars
We have determined accurate values of the product of the mass-loss rate and the ion fraction of P , Ṁq(P ), for a sample of 40 Galactic O-type stars by fitting stellar-wind profiles to observations of the Pv resonance doublet obtained with FUSE,ORFEUS/BEFS, and Copernicus. When P 4+ is the dominant ion in the wind (i.e., 0.5 . q(P ) ≤ 1), Ṁq(P ) approximates the mass-loss rate to within a facto...
