Shock-Cloud interaction in the Vela SNR: the XMM-Newton view
Abstract
The study of the clumpy and irregular features in th X-ray emission of middle-aged supernova remnants shells allows us to shed light on the various characteristic of the interstellar medium, like its structure and composition. We have observed with XMMNewton a small knot in the Vela SNR, which previous ROSAT studies have indicated as one of the best examples of an interaction between the SNR shock and an isolated cloud. Thanks to the combination of good spectral and spatial resolution of the EPIC camera, we attempt a comparison with numerical models, and we derive a better characterization of the nature of the X-ray emission. We have also derived an estimate of the metal abundances inside the cloud.
