Interaction of SNR shocks with thermally conducting, radiative clouds
Abstract
The shock wave of shell supernova remnants SNRs offers the unique opportunity to detect directly the structures of the interstellar medium both at large and small scales On the other hand the several physical effects at work during the interaction between the shock and the medium along with the superposition effects along a given light of sight require detailed modeling and high resolution observations in order to derive useful diagnostics Here we study the interaction of an evolved SNR shock front impacting on a small interstellar gas cloud through a 3D hydrodynamic model which takes into account the effects of radiative losses and thermal conduction We explore the interplay between the physical processes at work during the cloud evolution and their effect on the mass and energy exchange with the surrounding medium We also investigate the time-dependent X-ray emission originating from the shock-cloud interactions for two prototypical cases in which either thermal conduction or radiative cooling plays a dominant role in the cloud dynamics and energetic We study the correspondence between ideal and observable structures identifing a set of diagnostic tools which may be useful in the comparison with XMM-Newton and Chandra data of SNR shells
