Suzaku Observations of Supernova Remnant G93.3+6.9 (DA 530)
Abstract
Supernova remnants, and the chemical enrichment and energy they transport, are a key component in the development of galaxies. Necessarily, most studies focus on bright, easily observed remnants--a biased sample generally found in dense environments. In fact, most supernova likely occur in low density environments. Since they are consequently harder to observe these remnants represent a largely unseen but very important piece of the supernova puzzle, both in terms of understanding enrichment and also for collecting data to model the explosions in low density environments. The Crab pulsar is presumed to have originated from such a supernova, and would probably be unknown to us if not for the pulsar wind nebula. G93.3+6.9 is a shell-type supernova remnant, located in a low density region at high Galactic latitude, about 420 pc above the Galactic plane. It emits radio synchrotron emission at the blast wave edge but only weak, interior, extended thermal X-ray emission. We present images and spectral analysis of the X-ray emission observed with the XIS instrument on Suzaku in June 2006, from a series of 5 pointings totaling 70 ksecs.
