论文摘要
超新星残余物（SNR）的结构和形态反映了母新壁炉（SNE）的特性以及残留物扩展的不均匀环境的特征。将SNR的形态与在其父sne中开发的各向异性联系起来，对于获取与SNE相关的爆炸过程的许多方面的关键信息至关重要。如今，由于多维模型描述了从SN到SNR的长期演变以及在电磁谱中增长的质量和数量的观察数据，因此我们研究SNR连接的能力已得到了很大的改善。在这里，我们使用了“ Accordo Quadro Inaf-Cineca（2017）”框架中获得的数值资源以及Cineca Iscra奖N.HP10BARP6Y，以描述SNR从2000年龄在2000年龄的全面SNR中的SNR的完整演变。将我们的模拟与$ \ sim 350 $〜年龄的SNR Cassiopeia A（CAS A）的观察结果进行了比较。多亏了这些模拟，我们能够将SNR的物理，化学和形态学特性与控制SN爆炸的复杂阶段的物理过程联系起来。
The structure and morphology of supernova remnants (SNRs) reflect the properties of the parent supernovae (SNe) and the characteristics of the inhomogeneous environments through which the remnants expand. Linking the morphology of SNRs to anisotropies developed in their parent SNe can be essential to obtain key information on many aspects of the explosion processes associated with SNe. Nowadays, our capability to study the SN-SNR connection has been largely improved thanks to multi-dimensional models describing the long-term evolution from the SN to the SNR as well as to observational data of growing quality and quantity across the electromagnetic spectrum which allow to constrain the models. Here we used the numerical resources obtained in the framework of the "Accordo Quadro INAF-CINECA (2017)" together with a CINECA ISCRA Award N.HP10BARP6Y to describe the full evolution of a SNR from the core-collapse to the full-fledged SNR at the age of 2000 years. Our simulations were compared with observations of SNR Cassiopeia A (Cas A) at the age of $\sim 350$~years. Thanks to these simulations we were able to link the physical, chemical and morphological properties of a SNR to the physical processes governing the complex phases of the SN explosion.
