X-ray emission of young SN Ia remnants as a probe for an explosion model
Stockholm University, Faculty of Science, Department of Astronomy.
2004 (English)In: Advances in Space Research, ISSN 0273-1177, E-ISSN 1879-1948, Vol. 33, 392-397 p.Article in journal (Refereed) Published
Abstract [en]

We present results of hydrodynamical simulations of young supernova remnants. To model the ejecta, we use several models (discussed in the literature) of type Ia supernova explosions with different abundances. Our hydro models are one-dimensional and spherically symmetrical, but they take into account ionization kinetics with all important processes. We include detailed calculations for the X-ray emission, allowing for time-dependent ionization and recombination. In particular, we compare the computed X-ray spectra with recent XMM-Newton observations of the Tycho supernova remnant (SNR). Our goal is to find the most viable thermonuclear SN model that gives good fits to both these X-ray observations and typical SN Ia light curves.
