Supernova remnants and their X-ray emission

These proceedings report on X-ray images and high resolution spectra obtained from the Einstein Observatory for a variety of supernova remnants (SNR's). In addition, optical, radio and theoretical results are presented. The major topics discussed include: young SNR's, their structure, mass and interaction with the interstellar medium; middle-aged SNR's with emphasis on objects with center filled morphologies as seen in radio and X-ray; older SNR's and their effect upon the interstellar medium; compact objects associated with SNR's, and pulsars and SNR's in other galaxies. Among the new results presented is observational evidence for the presence of a reverse shock, enhanced elemental abundances, and non-equilibrium ionization in young SNR's. Activity from a neutron star is shown to play an important role or be otherwise present in a number of remnants, and X-ray, optical and radio results pertaining to SNR's in the Magellanic Clouds are included
