NLTE Radiative Transfer and Model Atmospheres of Hot Stars
Stellar atmospheres are open systems and thus cannot be in thermodynamic equilibrium (TE). The “Local Thermodynamic Equilibrium” (LTE) is a working hypothesis which assumes TE not for the atmosphere as a whole but for small volume elements. As a consequence, the atomic population numbers are depending only on the local (electron) temperature and electron density via the SahaBoltzmann equations....
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 کاملA grid of synthetic ionizing spectra for very hot compact stars from NLTE model atmospheres
The precise analysis of properties of planetary nebulae is strongly dependent on good models for the stellar ionizing spectrum. Observations in the UV – X-ray wavelength range as well as NLTE model atmosphere calculations of spectra of their exciting stars have shown that neither blackbody fluxes nor “standard” NLTE atmosphere models which are composed out of hydrogen and helium only are good a...
متن کاملA hydrodynamic scheme for two-component winds from hot stars
Aims. We have developed a time-dependent two-component hydrodynamics code to simulate radiatively-driven stellar winds from hot stars. Methods. We use a time-explicit van Leer scheme to solve the hydrodynamic equations of a two-component stellar wind. Dynamical friction due to Coulomb collisions between the passive bulk plasma and the line-scattering ions is treated by a time-implicit, semi-ana...
