Abstract

Mixed-morphology or thermal composite supernova remnants (SNRs), which appear as a regular shell-type SNRs in radio band, but centrally-peaked with thermal emission in the X-ray band, do not fit the predictions of the standard SNR evolution model. While the original classification is done largely using ROSAT and ASCA data, the results emerging from higher resolution data available with Chandra X-ray Observatory are revealing a more complex picture. Instead of one-component swept-up material dominated plasma, most of mixed-morphology SNRs now appear to have multi-component plasma with significant ejecta component. We will present the summary of the latest observations of mixed-morphology SNRs, and discuss the new properties and challenges to model them.
