Cool Stellar Atmospheres

2002
We give an overview about the state-of-the-art in cool stellar (and sub-stellar) atmosphere simulations. Recent developments in numerical methods and parallel supercomputers, as well as in the quality of input data such as atomic and molecular line lists have led to substantial improvements in the quality of synthetic spectra when compared to multi ...

Stellar Atmosphere Modeling

2004
In this note, the formalism used to compute a simple stellar atmosphere model is described. The definition of a stellar atmosphere is strongly connected with the radiation field crossing the boundary layers of a star: the atmosphere is composed of those layers where photons interact with matter for the last time before leaving the star.

The stellar atmospheres problem

Journal of Quantitative Spectroscopy and Radiative Transfer, 1971
Abstract This paper discusses the construction of model stellar atmospheres placing particular stress on the mathematical methods used. The basic equations and assumptions of the problem are presented. Techniques which reduce the transfer equation to a set of linear equations are developed.

Motions in Stellar Atmospheres

Publications of the Astronomical Society of the Pacific, 1959
It has become increasingly obvious that we should not regard stellar atmospheres as homogeneous and static but must study special effects of forces other than gravity if we are to gain any satisfactorily complete comprehension of the general behavior of these atmospheres.

Study of Stellar Atmospheres

1970
Abstract : The research completed under this grant provides an understanding of blue stragglers, partial calibration of the Stromgren uvby and H beta photometric systems, and some initial results concerning the nature of horizontal branch and post-horizontal branch evolution of Population 2 stars.
