Abstract
Shell-type supernova remnants in the adiabatic expansion stage can be described by the Sedov solutions set, which leads to estimates of some of the SNR parameters, like age, explosion energy and ISM density, from certain observed quantities of these objects. However, effective particle acceleration may affect considerably the evolution and X-ray emission from SNRs. Using hydrodynamic simulations coupled with diffusive shock acceleration, we investigate the effects of cosmic ray acceleration on the spectrum and radius of the SNRs, and hence we establish how cosmic-ray production affects the Sedov predictions for the original parameters. Furthermore, we explore how these simulated spectra fit SNR observations, and look for possible modifications to the estimated parameters established assuming no particle acceleration has taken place.
