The remnant of Kepler's supernova (SN 1604) is the youngest remnant in the Milky Way with a well determined age. It is a bright, compact (roughly 3.5 arcmin in diameter) and highly structured X-ray source. However, unlike the other young Galactic supernova remnants, Tycho and Cas A, to date little has been published on the Chandra observation of Kepler. In this work, we present a comprehensive analysis of the first 50 ks of Chandra data acquired in 2000, using a principal components analysis. We find four significant spectral components that, broadly speaking, delineate thermal and nonthermal spectral components, regions of excess X-ray absorption, and abundance variations of Si, Fe, and other species.
Research on the Kepler supernova remnant at Rutgers has been supported by Chandra grants.
