Session 53 - SNs, Planetaries and Circumstellar Disks.
Display session, Wednesday, June 10
We present examples from a forthcoming atlas of narrow-band X-ray images of supernova remnants (SNR) obtained with the ASCA observatory. These ASCA images map SNRs in several energy bands between 1-10 keV and provide the first maps in the energy band above 4 keV and in individually resolved emission lines and continuum features. Recent studies of the bright SNRs Cas-A and Tycho reveal complex spatial morphologies in various line emission bands and allow the elemental abundances and temperature distribution to be mapped out across the remnants. We concentrate on Galactic SNRs which are resolved by the ASCA telescope. Here, we summarize the current ASCA observations, and demonstrate the techniques used to create the exposure-corrected line-resolved maps from single and multiple observations of SNRs, for all four imaging instruments aboard ASCA.
