| Abstract: |
An observational program to monitor the H-alpha emission of early-type stars and to study the mass loss properties of early-type stars is discussed. Preliminary H-alpha observations of nine O stars, one B star, and one A star are presented from June, 1988. Plans to continue long-term observations of these stars are discussed. The model used to interpret the data is outlined, including the assumptions on which the model is based. In the model, H-alpha emission from the stellar wind is a monotonically increasing function of its optical depth. The preliminary observations are analyzed in terms of the proposed model. |
