[19.07] BBXRT Observations of Fe Lines in Cas A

A.E.Szymkowiak (NASA/GSFC)

The Broad Band X-Ray Telescope (BBXRT) observations of the supernova remnant(SNR) Cas A provided the first examination of the region of the x-ray spectrum around 6 keV with a spectrometer with sufficient resolution (FWHM circa 180 eV) to partially resolve the Fe lines. The observed line complex is inconsistent with a single narrow line. Additionally, we have not been able to obtain a good fit with models of the X-ray emission from a Sedov-type SNR. We will discuss what types of combinations of emissions could be consistent with the data
