- W1674472187 abstract "Emission lines are often observed in high luminosity stars and provide evidence of the presence of extended stellar envelopes. Ha is the most frequently observed across the H-R diagram, but lines of HeI or FeII are also found in emission in these stars. They could be used as diagnostics of the structure of their outer atmospheres and winds. High resolution (1/dl ~ 105) high S/N profiles of Ha and HeI 5876 in the galactic LBVs (eta) Car, AG and HR Car, and in the LMC star S22 have been obtained with the ESO CAT-CES during 1984–87, and are described in Figs.1–5. We find that these stars show a large variety of profiles with narrow and broad emissions, wide or multiple blue-shifted absorptions. The profiles are largely variable. Once, a kind of inverse P Cyg profile was observed in HR Car (Fig.4). These results indicate the presence of large scale phenomena and high velocity fields which are dramatically variable in time. Continuos HIRES monitoring of these stars is urgently needed." @default.
