Expanding atmospheres in OB supergiants-III. P. Cygni
Abstract
Spectroscopic observations of P Cygni indicate the existence and structure of an extended accelerating envelope about the star. The structure is used as a basis for strong line profile computations, and modified to match computed and observed profiles. The final atmospheric structure resembles that found for three other supergiants and indicates a rate of mass loss from P -4M0yr-'.
