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 $\rm \sim 0.20-2.00~10^{51}~erg$. The main outcomes of these simulations, i.e., remnant mass, $\rm ^{56}Ni$ 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 $\rm 7.83~Mpc$, the properties of the light curve point toward a progenitor with an initial mass of $\rm 13~M_\odot$ and a metallicity [Fe/H]=-1. If, on the contrary, the adopted distance modulus is $\rm 11.7~Mpc$, all the models with initial mass $13\leq M/M_\odot\leq 15$ and metallicities $\rm -1\leq [Fe/H] \leq 0$ are compatible with the progenitor of SN 1999em.

使用 HYPERION 对核心坍缩超新星的光曲线进行流体动力学建模。I. 质量范围 13-25 M ⊙,金属度 -3 ≤ [Fe/H] ≤ 0,SN 1999em 的情况

我们展示了 {\scshape{Hyperion}}(带辐射扩散的水动力 Ppm 爆炸)的最新版本,这是一种流体动力学代码,旨在计算与大质量恒星爆炸相关的爆炸核合成、残余质量和光变曲线。通过这段代码,我们计算了红超巨星模型子集的爆炸,取自 \cite{lc18} 发布的数据库,对于 $\rm \sim 0.20-2.00~10^{51} 范围内的各种爆炸能量~erg$。这些模拟的主要结果,即残余质量、$\rm ^{56}Ni$ 合成、光度和热光曲线平台的长度,被分析为恒星初始参数(质量和金属性)和爆炸能量。作为 {\scshape{Hyperion}} 的第一个应用,我们通过光变曲线拟合估计了 SN 1999em 的前身星的质量和金属丰度,SN 1999em 是一个经过充分研究的 SN IIP。特别地,如果采用的与宿主星系 NGC 1637 的距离为 $\rm 7.83~Mpc$,则光变曲线的特性指向初始质量为 $\rm 13~M_\odot$ 且金属丰度 [ Fe/H]=-1。相反,如果采用的距离模量为 $\rm 11.7~Mpc$,则所有初始质量 $13\leq M/M_\odot\leq 15$ 和金属量 $\rm -1\leq [Fe/H ] \leq 0$ 与 SN 1999em 的祖先兼容。光变曲线的特性指向初始质量为 $\rm 13~M_\odot$ 和金属丰度 [Fe/H]=-1 的前体。相反,如果采用的距离模量为 $\rm 11.7~Mpc$,则所有初始质量 $13\leq M/M_\odot\leq 15$ 和金属量 $\rm -1\leq [Fe/H ] \leq 0$ 与 SN 1999em 的祖先兼容。光变曲线的特性指向初始质量为 $\rm 13~M_\odot$ 和金属丰度 [Fe/H]=-1 的前体。相反,如果采用的距离模量为 $\rm 11.7~Mpc$,则所有初始质量 $13\leq M/M_\odot\leq 15$ 和金属量 $\rm -1\leq [Fe/H ] \leq 0$ 与 SN 1999em 的祖先兼容。
