UV observations of γ Cas: intermittent mass-loss enhancement
Description
Twenty one high resolution IUE observations made over a two year interval revealed remarkable changes in the profiles of the resonance lines of C IV, N V and Si IV in the B 0.5 IVe star γ Cas. Narrow (FWHM < 100 km s-1), blue shifted (v < 1500 km s-1), absorption components of varying strengths are observed in addition to the broad, asymmetric, low-velocity absorption lines which seem to be steady. An earlier proposed model to explain this phenomenon (the UV-shell model by Henrichs et al. 1980) has now been tested and probably confirmed by new observations which were taken with high time resolution.
