Combined Stellar Structure and Atmosphere Models for Massive Stars Ii. Spectral Evolution on the Main Sequence
In Schaerer et al. (1995, Paper I) we have presented the rst \combined stellar structure and atmosphere models" (CoStar) for massive stars, which consistently treat the entire mass loosing star from the center out to the outer region of the stellar wind. The models use up-to-date input physics and state-of-the-art techniques to model both the stellar interior and the spherically expanding non{L...
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...

متن کاملThermalisation of Electrons in a Stellar Atmosphere
We are interested in electrons kinetics in a stellar atmosphere to validate or invalidate the usually accepted hypothesis of thermalisation of electrons. For this purpose, we calculate the velocity distribution function of electrons by solving the kinetic equation of these particles together with the equations of radiative transfer and statistical equilibrium. We note that this distribution can...
متن کاملSpatial/Spectral Resolution of a Galactic Bulge K3 Giant Stellar Atmosphere via Gravitational Microlensing
We present two Keck HIRES spectra (λ/∆λ = 40, 000) of a bulge K3 giant taken on successive nights during the second caustic crossing of the binary microlensing event EROS BLG-2000-5. This caustic crossing served effectively to resolve the surface of the source star: the spectrum from the second night is dominated by the limb, while the spectrum from the first night is comprised of light from a ...
