Outflow or galactic wind: The fate of ionized gas in the halos of dwarf galaxies
J. van Eymeren, D. J. Bomans, K. Weis +1
Context: Hαimages of star bursting irregular galaxies reveal a large amount of extended ionized gas structures, in some cases at kpc-distance away from any place of current star fo…
Variable Unidentified Emission Near 6307 AA in Eta Carinae
J. C. Martin, K. Davidson, F. Hamann +2
We have discovered a conspicuous unidentified variable feature near 6307 AA in the spectrum of Eta Carinae which is spatially unresolved from the central star and its wind (r < 200…
The UV Scattering Halo of the Central Source Associated with Eta Carinae
D. John Hillier, T. Gull, K. Nielsen +8
We have made an extensive study of the UV spectrum of Eta Carinae, and find that we do not directly observe the star and its wind in the UV. Because of dust along our line of sight…
A spectroscopic event of eta Car viewed from different directions: The data and first results
Otmar Stahl, Kerstin Weis, Dominik J. Bomans +3
We present spectroscopic observations with high spectral resolution of eta Car as seen by the SE lobe of the Homunculus nebula over the 2003.5 "spectroscopic event". The observed s…
SN2002kg -- the brightening of LBV V37 in NGC 2403
Kerstin Weis, Dominik J. Bomans
SN2002kg is a type IIn supernova, detected in October 2002 in the nearby spiral galaxy NGC 2403. We show that the position of SN2002kg agrees within the errors with the position of…
A Change in the Physical State of Carinae?
K. Davidson, J. C. Martin, R. M. Humphreys +8
During Car's spectroscopic event in mid-2003, the stellar wind's bright H and H emission lines temporarily had a distinctive shape unlike that reported on any previous oc…
