▪ Abstract This review deals with the winds from “normal” hot stars such as O-stars, B- and A-supergiants, and Central Stars of Planetary Nebulae with O-type spectra. The advanced diagnostic methodsExpand
Stellar and wind parameters of Galactic O-stars - The influence of line-blocking/blanketing
We have re-analyzed the Galactic O-star sample from [CITE] by means of line-blanketed NLTE model atmospheres in order to investigate the influence of line-blocking/blanketing on the derivedExpand
Mass loss from hot massive stars
Mass loss is a key process in the evolution of massive stars, and must be understood quantitatively if it is to be successfully included in broader astrophysical applications such as galactic andExpand
The empirical metallicity dependence of the mass-loss rate of O- and early B-type stars
We present a comprehensive study of the observational dependence of the mass-loss rate in stationary stellar winds of hot massive stars on the metal content of their atmospheres. The metal content ofExpand
A Medium Resolution Near-Infrared Spectral Atlas of O and Early-B Stars
We present intermediate-resolution (R ~ 8000-12,000) high signal-to-noise (S/N) H- and K-band spectroscopy of a sample of 37 optically visible stars, ranging in spectral type from O3 to B3 andExpand
Ephemeris, orbital decay, and masses of ten eclipsing high-mass X-ray binaries
We update the ephemeris of the eclipsing high-mass X-ray binary (HMXB) systems LMC X-4, Cen X-3, 4U 1700-377, 4U 1538-522, SMC X-1, IGR J18027-2016, Vela X-1,IGR J17252-3616, XTE J1855-026, and OAOExpand
Bright OB stars in the Galaxy. III. Constraints on the radial stratification of the clumping factor
Context. Recent results strongly challenge the canonical picture of massive star winds: various evidence indicates that currently accepted mass-loss rates, u M, may need to be revised downwards, byExpand
The Physical Properties and Effective Temperature Scale of O-Type Stars as a Function of Metallicity. II. Analysis of 20 More Magellanic Cloud Stars and Results from the Complete Sample
In order to determine the physical properties of the hottest and most luminous stars and understand how these properties change as a function of metallicity, we have analyzed HST/UV and high-S/NExpand
Atmospheric NLTE-models for the spectroscopic analysis of blue stars with winds. II. Line-blanketed models
Received; accepted Abstract. We present new or improved methods for calculating NLTE, line-blanketed model atmospheres for hot stars with winds (spectral types A to O), with particular emphasis on aExpand
Radiation driven winds of hot luminous stars - XIV. Line statistics and radiative driving
This paper analyzes the inter-relation be- tween line-statistics and radiative driving in massive stars with winds (excluding Wolf-Rayets) and provides insight into the qualitative behaviour of theExpand
