Scientific paper

Superbubbles (SBs) are formed by the combined actions of stellar winds and supernova explosions from massive stars in OB associations. These objects contribute significantly to the hot gas component of a galaxy's interstellar medium (ISM), as well as affecting the structure of the ISM to large scales. We propose XMM-Newton observations of three X-ray prominent superbubbles in the Large Magellanic Cloud: N57, N103, and N185. From these X-ray spectral data, we will investigate (a) the energy budgets of these SBs, and whether those are consistent with expected stellar-wind inputs; (b) the required input of SNRs to these SBs to obtain the observed energies, and (c) enhanced abundances indicating recent enrichment by SN ejecta.
