Imaging the outflow of 2 MK gas from the Orion Nebula

Our discovery of diffuse Xray emission in the Orion Nebula has demonstratedthat hot bubbles, created by shocks in the powerful, hypersonic winds of highmass stars, are a common feature of highmass starforming regions, not onlythose that host many early Otype stars. Pressure equilibrium with the HII gasand an apparent stream of 1.8 MeV emission, caused by the radioactive decay of26Al, connecting the Nebula region to the nearby Eridanus Superbubble suggestthe hot gas is not confined. The outflow of hot gas from such regions couldprovide a continual source of enrichment of the ISM, complementary to thediscrete but rare input of supernovae. Our aim is to directly image the outflowof Xrayemitting hot gas from the Orion Nebula. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
