Continuum Emission from a Rotating Non-Gray Stellar Atmosphere.

This paper is an attempt to extend and revise the results of an earlier paper In the earlier work, the continuum emission of an early, rapidly rotating star was predicted under the assumptions of a gray atmosphere, Roche model, and Von Zeipel's theorem In this study the assumption of a gray atmosphere has been replaced by a series of non-gray atmospheres calculated by means of the Str6mgren-Underhill Atmosphere-Computer Program. A more accurate formulation of the problem, along with a more sophisticated numerical integration scheme has been employed. The results of the earlier paper have, by and large, been substantiated. That is, the gray atmosphere proved to be a moderately good approximation in the visible range and a rather poor approximation in the ultraviolet. However, the effects indicated by the earlier study have been shown to be of the correct form but of too small a magnitude. A variation of up to 1.4 mag in the few ultraviolet colors due to effects of rotation may be expected.
