Line-blanketed model atmospheres for R Coronae Borealis stars and hydrogen-deficient carbon stars
We have constructed line-blanketed model atmospheres for the hydrogen-deficient and carbon-rich R Coronae Borealis (RCrB) stars, as well as for the similar hydrogendeficient carbon (HdC) stars and the cool extreme helium (EHe) stars. Improved continuum opacities have been used together with realistic line absorption data for atomic andmolecular transitions. The observed dereddened fluxes of R C...
متن کاملSpectral analyses with line-blanketed model atmospheres versus stellar evolution models with and without rotation
Context. Very massive stars pass through the Wolf-Rayet (WR) stage before they finally explode. Details of their evolution have not yet been safely established, and their physics are not well understood. Their spectral analysis requires adequate model atmospheres, which have been developed step by step during the past decades and account in their recent version for line blanketing by the millio...
متن کاملHydrodynamic model atmospheres for WR stars: Self-consistent modeling of a WC star wind
We present the first non-LTE atmosphere models for WR stars that incorporate a self-consistent solution of the hydrodynamic equations. The models account for iron-group line-blanketing and clumping, and compute the hydrodynamic structure of a radiatively driven wind consistently with the non-LTE radiation transport in the co-moving frame. We construct a self-consistent wind model that reproduce...
متن کاملHydrogen model atmospheres for white dwarf stars
We present a detailed calculation of model atmospheres for DA white dwarfs. Our atmosphere code solves the atmosphere structure in local thermodynamic equilibrium with a standard partial linearization technique, which takes into account the energy transfer by radiation and convection. This code incorporates recent improved and extended data base of collision induced absorption by molecular hydr...
متن کاملAtmospheric NLTE-Models for the Spectroscopic Analysis of Blue Stars with Winds II. Line-Blanketed Models
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 a fast performance. These methods have been implemented into a previous, more simple version of the model atmosphere code F (Santolaya-Rey et al. 1997) and allow to spectroscopically analyze rather large samples of massive...
