Spectroscopic survey of emission-line stars. I. B[e] stars
Anna Aret, Michaela Kraus, Miroslav Šlechta
Emission-line stars are typically surrounded by dense circumstellar material, often in form of rings or disc-like structures. Line emission from forbidden transitions trace a diver…
Forbidden calcium lines as disc tracers
Anna Aret, Michaela Kraus
Forbidden emission lines are particularly valuable disc tracers, because their profiles reflect the kinematics within their formation region. Here we present a short excerpt from t…
Disk tracing for B[e] supergiants in the Magellanic Clouds
G. Maravelias, M. Kraus, A. Aret
B[e] supergiants are evolved massive stars with a complex circumstellar environment. A number of important emission features probe the structure and the kinematics of the circumste…
Interplay between pulsations and mass loss in the blue supergiant 55 Cygnus = HD 198478
M. Kraus, M. Haucke, L. S. Cidale +14
Blue supergiant stars are known to display photometric and spectroscopic variability that is suggested to be linked to stellar pulsations. Pulsational activity in massive stars str…
