论文摘要
超新星残留物（SNR）是超新星（SNE，核心爆发或热核能）的结果。残留物是由于恒星喷射和祖细胞周围的环境介质之间的相互作用而产生的。年轻的SNR的特征是强烈的冲击，使气体加热和电离，产生磁动力动力湍流，并加速颗粒到相对论能量。它们在所有波长中散发出来，尤其是在X射线域中，在X射线域中，光谱图像的观测值可以提供大量信息。本文提出了SNR的建模的最新进展，尤其是通过数值模拟的方式，并着重于三维方面。在第一部分中，我们将SNRs视为宇宙射线的生产商（CRS）。如果SNR具有足够有效的加速器来为CRS的银河系分量供电，则必须对其动力学，因此对等离子体的热发射以及其非热发射产生明显的影响。在第二部分中，我们将SNRs视为爆炸机制的探针。现在是时候连接SNR和SNR的SNE模拟的多维模拟，开放了通过SNR的动力学和形态研究爆炸机制的可能性。
Supernova remnants (SNRs) are the outcome of supernovae (SNe, either core-collapse or thermonuclear). The remnant results from the interaction between the stellar ejecta and the ambient medium around the progenitor star. Young SNRs are characterized by strong shocks that heat and ionize the gas, generate magneto-hydrodynamic turbulence, and accelerate particles to relativistic energies. They radiate at all wavelengths, especially in the X-ray domain, where spectro-imaging observations can provide a wealth of information. This paper presents recent progress in the modelling of SNRs, particularly by the means of numerical simulations, and with a focus on three-dimensional aspects. In the first part we will consider SNRs as producers of cosmic rays (CRs). If SNRs are accelerators efficient enough to power the Galactic component of CRs, this must have a visible impact on their dynamics, and therefore on the thermal emission from the plasma, as well as on their non-thermal emission. In the second part we will consider SNRs as probes of the explosion mechanism. The time has come to connect multi-dimensional simulations of SNe and simulations of SNRs, opening the possibility to study the explosion mechanism via the dynamics and morphology of SNRs.
