Stellar Winds from Massive Stars
We review the various techniques through which wind properties of massive stars – O stars, AB supergiants, Luminous Blue Variables (LBVs), Wolf-Rayet (WR) stars and cool supergiants – are derived. The wind momentum-luminosity relation (e.g. Kudritzki et al. 1999) provides a method of predicting mass-loss rates of O stars and blue supergiants which is superior to previous parameterizations. Assu...
متن کاملSynthetic spectra of massive stars as tool for the spectral analysis of stars and stellar clusters
We present fully consistent models for O-type stars that re-produce the observed UV spectra simultaneously with the observed ter-minal velocities and mass loss rates. We demonstrate how, as a conse-quence, the models can be used to determine the stellar parameters fromthe observed UV spectra alone. 1. Comparison with observations For a detailed description of the treatment of no...
متن کاملFundamental Parameters of Massive Stars
We discuss the determination of fundamental parameters of ‘normal’ hot, massive OB-type stars, namely temperatures, luminosities, masses, gravities and surface abundances. We also present methods used to derive properties of stellar winds – mass-loss rates and wind velocities from early-type stars.
متن کاملCombined stellar structure and atmosphere models for massive stars III. Spectral evolution and revised ionizing fluxes of O3-B0 stars
We provide an extensive set of theoretical spectral energy distributions of massive stars derived from our “combined stellar structure and atmosphere models”. The calculations cover the entire main sequence evolution for initial masses Mi = 20 – 120M , corresponding to O3–B0 stars of all luminosity classes. We predict detailed line blanketed UV spectra along the main sequence evolution. The maj...
