行星状星云、船底座η星和超新星遗迹与星际介质的相互作用
Interaction of planetary nebulae, Eta-Carinae and supernova remnants with the Interstellar Medium
摘要：
行星状星云（PN）、超新星遗迹（SNR）和船底座η星的图像是由三种不同的物理过程形成的。第一个过程是壳层的膨胀，在球壳的情况下可以用正则运动定律来模拟，在星际介质中存在密度梯度时可以用动量守恒来模拟。模拟的质量沿着一个方向以及沿着许多方向引入。第二个过程是粒子从前进层辐射的扩散。分析了球的三维扩散、一维漂移扩散和一维随机游动扩散。第三个过程是通过沿视线的积分运算合成图像。该框架被应用到三个PN，这是A39，环形星云和蚀刻沙漏星云MyCn 18，混合对象Eta-Carinae，和两个SNR，这是SN 1993 J和SN 1006。在所有考虑的情况下，仔细比较观察到的和理论的配置文件的强度。
英文摘要：
The image of planetary nebulae (PN), supernova remnant (SNR) and Eta-Carinae is made by three different physical processes. The first process is the expansion of the shell that can be modeled by the canonical laws of motion in the spherical case and by the momentum conservation when gradients of density are present in the interstellar medium. The quality of the simulations is introduced along one direction as well along many directions. The second process is the diffusion of particles that radiate from the advancing layer. The 3D diffusion from a sphere, the 1D diffusion with drift and 1D random walk are analyzed. The third process is the composition of the image through an integral operation along the line of sight. The developed framework is applied to three PN which are A39, the Ring nebula and the etched hourglass nebula MyCn 18, the hybrid object Eta-Carinae, and to two SNR which are SN 1993J and SN 1006. In all the considered cases a careful comparison between the observed and theoretical profiles in intensity is done.
