Determination of the Thermal and Non-Thermal Emissions in the X-Ray Spectrum of Kepler's Supernova Remnant.
Abstract
The XTE/PCA instrument, with its large efficiency and wide energy range, offers an unique opportunity to observe the high energy X-ray emission of Kepler's supernova remnant. Previous observations in the 0.1-10 keV range (EINSTEIN, EXOSAT, GINGA, ROSAT and ASCA) have favored non-equilibrium ionization reverse shock models. A very high temperature (24 keV) is predicted in the shocked interstellar medium by these models. Observation of this high energy component will put strong constraints on the SN type and SNR evolution. The other major objective is to seek for an X-ray synchrotron emission in addition to the thermally produced X-rays. The observational goal for XTE PCA is thus to determine both these thermal and non-thermal contributions in the Kepler's high energy spectrum.
