Journal ArticleDOI
Mass-loss predictions for O and B stars as a function of metallicity
TL;DR: In this paper, a grid of massive star wind models and mass-loss rates for a wide range of metal abundances between 1/100 and 10 Z/Zsun was calculated.
Journal ArticleDOI
On the metallicity dependence of Wolf-Rayet winds
Jorick S. Vink,Alex de Koter +1 more
TL;DR: In this article, the authors performed a pilot study of mass loss predictions for late-type Wolf-Rayet (WR) stars as a function of metal abundance, over a range between 10 − 5 − 3 < (Z/Zsun) < 10.
Journal ArticleDOI
The ionization in the winds of o stars and the determination of mass-loss rates from ultraviolet lines
TL;DR: In this paper, the authors derived the mass-loss rates derived from radio measurements and Ha with the line-tting of ultraviolet resonance lines and subordinate lines using the Sobolev plus exact integration (SEI) method.

TL;DR: In this paper, an optical analysis of 55 members of R136, the central cluster in the Tarantula Nebula of the Large Magellanic Cloud, was performed with STIS aboard the Hubble Space Telescope.

New theoretical Mass-loss rates of O and B Stars
TL;DR: In this article, a grid of wind models covering a wide range of stellar parameters and a mass-loss recipe for two ranges of effective temperature at either side of the bi-stability jump around spectral type B1 were derived.
