Abstract:We estimate the progenitor and explosion properties of the nearby Type II SN 2023ixf using a synthetic model grid of Type II supernova light curves. By comparing the light curves of SN 2023ixf with the pre-existing grid of Type II supernovae containing about 228000 models with different combinations of the progenitor and explosion properties, we obtain the $\chi ^2$ value for every model and evaluate the properties of the models providing small values of $\chi ^2$. We found that the light-curve models with a p… Show more
