The Stability of Stellar Atmospheres
Publications of the Astronomical Society of Australia, 1984There have been extensive calculations of model atmospheres of stars over the past few decades. Almost all of these calculations have assumed radiative equilibrium. Except for convection, very little work has been done on the stability of the surface layers of stars at small optical depths.

Molecules in Stellar Atmospheres
Astrophysics and Space Science, 1997The effects of molecules on model stellar atmospheres are briefly reviewed. Molecular diagnostics of stellar fundamental parameters and of atmospheric structure are discussed, and the presently emerging "ISO picture" of the outer regions of stars is commented upon.

Stellar atmospheres as a plasma
Il Nuovo Cimento, 1959Equations of motion and Ohm's law for an ionized gas in a stellar atmosphere are presented. Ambiguities in plasma physics relative to the solar atmosphere, sunspots, the heating mechanism of the chromosphere and the corona, and the state of ionization of the solar corona are discussed, The hydromagnetic ambiguities of interplanetary space are discussed

Motions in Stellar Atmospheres
Publications of the Astronomical Society of the Pacific, 1959It 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.

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.

This report has been prepared by the President in collaboration with the Secretary of the Commission. It is based on (1) material supplied by those members and associates of the Commission who responded to requests made in our circulars, (2) a bibliographical search intended to supplement the above material, (3) discussions with other interested ...

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.
