O VI emission from superbubbles in the Large Magellanic Cloud.

SANKRIT R. and DIXON W.V.D.

Abstract (from CDS):

Observations of interstellar regions in the Large Magellanic Cloud (LMC) obtained serendipitously by the Far Ultraviolet Spectroscopic Explorer (FUSE) have revealed O VI λ1032 emission from several superbubbles and from one region not associated with any nebula. In every case, the O VI emission is centered at or around the LMC velocity of +275 km/s. The O VI surface brightnesses (8900-21,800 LU [line unit; 1 photon/s/cm2/sr]) toward superbubbles are significantly higher than the value (6400 LU) in the one LMC diffuse-gas spectrum, and also higher than in spectra of the diffuse hot gas emission in our Galaxy (Dixon et al.). The superbubble O VI brightnesses are lower than those of supernova remnants, but their values are consistent with the emission arising in supernova-driven shocks. However, other emission mechanisms, such as conductive interfaces and turbulent mixing layers, are not excluded by our data.
