Estimating Ejecta Mass Ratios in Kepler’s Supernova Remnant: Global X-Ray Spectral Analysis Including Suzaku Systematics and Emitting Volume Uncertainties by Tyler Holland-Ashford, Patrick Slane, Laura A. Lopez, Katie Auchettl, Vinay Kashyap

“…In this work, we analyze the global Suzaku X-ray spectrum of Kepler’s supernova remnant (SNR) in order to constrain the mass ratios of various ejecta species synthesized during explosion. Critically, we account for the Suzaku telescope effective-area calibration uncertainties of 5%–20% by generating 100 mock effective-area curves and using Markov Chain Monte Carlo–based spectral fitting to produce 100 sets of best-fit parameter values. …”
