A New LBV Candidate in M33
John C. Martin, Roberta M. Humphreys, Kerstin Weis +1
The evolutionary relationships and mechanisms governing the behavior of the wide variety of luminous stars populating the upper H-R diagram are not well established. Luminous blue…
Multi-epoch variability of AT 2000ch (SN 2000ch) in NGC 3432 -- A radio continuum and optical study
Ancla Müller, Vanessa Frohn, Lukas Dirks +5
AT 2000ch is a highly variable massive star and supernova imposter in NGC 3432 first detected in 2000. It is similar and often compared to SN 2009ip, and it is therefore expected t…
Modelling O-star astrospheres with different relative speeds between the ISM and the star: 2D and 3D MHD model comparison
L. R. Baalmann, K. Scherer, J. Kleimann +3
Context. State of the art simulations of astrospheres are modelled using three-dimensional (3D) magnetohydrodynamics (MHD). An astrospheric interaction of a stellar wind (SW) with…
Luminous Blue Variables
Kerstin Weis, Dominik J. Bomans
Luminous Blue Variables are massive evolved stars, here we introduce this outstanding class of objects. Described are the specific characteristics, the evolutionary state and what…
MHD-shock structures of astrospheres: Cephei-like astrospheres
K. Scherer, L. R. Baalmann, H. Fichtner +5
The interpretation of recent observations of bow shocks around O-stars and the creation of corresponding models require a detailed understanding of the associated (magneto-)hydrody…
The interaction of multiple stellar winds in stellar clusters: potential flow
Klaus Scherer, Alexander Noack, Jens Kleimann +2
While several studies have investigated large-scale cluster winds resulting from an intra-cluster interaction of multiple stellar winds, as yet they have not provided details of th…
