X-rays from superbubbles in the Large Magellanic Cloud. VI. A sample of thirteen superbubbles.

Abstract (from CDS):

We present ROSAT observations and analysis of thirteen superbubbles in the Large Magellanic Cloud. Eleven of these observations have not been previously reported. We have studied the X-ray morphology of the superbubbles and have extracted and analyzed their X-ray spectra. Diffuse X-ray emission is detected from each of these superbubbles, and X-ray emission is brighter than that theoretically expected for a wind-blown bubble, suggesting that the X-ray emission from the superbubbles has been enhanced by interactions between the superbubble shell and interior supernova remnants. We have also found significant positive correlations between the X-ray luminosity of a superbubble and its Hα luminosity, expansion velocity, and OB star count. Further, we have found that a large fraction of the superbubbles in the sample show evidence of breakout regions, where hot X-ray-emitting gas extends beyond the Hα shell.
