Hydrodynamical modeling of the light curves of core collapse supernovae with HYPERION. I. The mass range 13-25 Msun, the metallicities -3<=[Fe/H]<=0 and the case of SN1999em

Abstract

We present the last version of {\scshape{Hyperion}} (HYdrodynamic Ppm Explosion with Radiation diffusION), a hydrodynamic code designed to calculate the explosive nucleosynthesis, remnant mass and light curve associated to the explosion of a massive star. By means of this code we compute the explosion of a subset of red supergiant models, taken from the database published by \cite{lc18}, for various explosion energies in the range $\sim 0.20-2.0010^{51}\mathrm{erg}$. The main outcomes of these simulations, i.e., remnant mass, ${}^{56}\mathrm{Ni}$ synthesized, luminosity and length of the plateau of the bolometric light curve, are analyzed as a function of the initial parameters of the star (mass and metallicity) and of the explosion energy. As a first application of {\scshape{Hyperion}} we estimated the mass and the metallicity of the progenitor star of SN 1999em, a well studied SN IIP, by means of the light curve fitting. In particular, if the adopted distance to the host galaxy NGC 1637 is $7.83\mathrm{Mpc}$, the properties of the light curve point toward a progenitor with an initial mass of $13{\mathrm{M}}_{\odot }$ and a metallicity [Fe/H]=-1. If, on the contrary, the adopted distance modulus is $11.7\mathrm{Mpc}$, all the models with initial mass $13\le M/M_{\odot }\le 15$ and metallicities $-1\le [Fe/H]\le 0$ are compatible with the progenitor of SN 1999em.
