超新星遗迹的第一个三维形态运动学模型：VRO 42.05.01（G 166.0+4.3）事例
The first 3D Morpho-kinematical model of a Supernova Remnant: The case of VRO 42.05.01 (G 166.0+4.3)
摘要：
我们提出了第一个三维（3D）形态运动学（MK）模型的超新星遗迹（SNR）的初步结果，作为一个研究案例，银河系SNR VRO 42.05.01（G 166.0+4.3）。为了我们的建模的目的，天体物理软件SHAPE中使用的宽视场成像和高分辨率光谱数据。我们发现，残余物是由三个基本的独特的组成部分：一个“壳”，一个“翅膀”和一个“帽子”，呈现出不同的形态和运动学行为，可能是由于不同的环境介质属性。整个星云相对于天球平面的倾角为$6-8$度，系统速度为$V_{\rm sys}$ $\sim$ -15到-25 km/s。最后，我们讨论了我们的模型的结果的起源和演变的VRO 42.05.01的可能影响。
英文摘要：
We present the preliminary results of the first 3-dimensional (3D) Morpho-Kinematical (MK) model of a supernova remnant (SNR), using as a study case the Galactic SNR VRO 42.05.01 (G 166.0+4.3). For the purpose of our modelling, the astrophysical software SHAPE was employed in which wide field imaging and high resolution spectroscopic data were utilized. We found that the remnant is consisted by three basic distinctive components: a "shell", a "wing" and a "hat", which present different morphological and kinematical behaviour, probably due to different ambient medium properties. The whole nebula has an inclination of $6-8$ degrees with respect to the plane of the sky and a systemic velocity $V_{\rm sys}$ $\sim$ -15 to -25 km/s. Finally, we discuss the possible implications of our model's results on the origin and evolution of VRO 42.05.01.
