The feedback of massive stars on the ISM: XMM-Newton view of the LMC superbubble N51D
Dominik J. Bomans, Joern Rossa, Kerstin Weis +1
N51D (= DEM L 192) appears at first glance as a nearly circular, 120pc diameter bubble of ionized gas around the LMC OB association LH 54. A deeper look reveals a complex web of fi…
Warm and Hot Diffuse Gas in Dwarf Galaxies
Dominik J. Bomans
Dwarf galaxies provide a special environment due to their low mass, small size and generally low metal content. These attributes make them perfect laboratories for the interaction…
ORFEUS II echelle spectra: On the H_2/CO ratio in the LMC towards LH 10
P. Richter, K. S. de Boer, D. J. Bomans +3
ORFEUS far UV echelle spectra have been used to investigate HI, H_2 and CO absorption lines along the line of sight towards LH 10:3120 in the LMC, extending the study presented by…
No stellar age gradient inside supergiant shell LMC 4
Jochen M. Braun, Dominik J. Bomans, Jean-Marie Will +1
The youngest stellar populations of a 'J'-shaped region (400 pc strip E-W across LH 77 and 850 pc S-N) inside the supergiant shell (SGS) LMC 4 (with a diameter of 1.4 kpc) have bee…
NGC 1427A - an LMC type galaxy in the Fornax Cluster
M. Hilker, D. J. Bomans, L. Infante +1
We have discovered that the Fornax irregular galaxy NGC 1427A is in very many respects a twin of the Large Magellanic Cloud. Based on B, V, I, and H alpha images, we find the follo…
The bipolar structure of the LBV nebula around HR Carinae
K. Weis, W. J. Duschl, D. J. Bomans +2
HR Carinae is one of the few Luminous Blue Variables (LBVs) in the Galaxy. It has a nebula that appears bipolar. We have obtained imaging and high-dispersion, long-slit echelle dat…
