论文摘要
我们介绍了超新星残留物（SNR）的前三维（3D）形态基因（MK）模型，使用作为案例研究，Galactic SNR VRO 42.05.01。我们采用了天体物理代码形状，其中利用了广泛的现场成像和高分辨率光谱数据来重建其3D形态和运动学。我们发现残留物由我们称为的三个基本独特组成部分组成：“外壳”，“机翼”和“帽子”。关于它们的运动行为，我们发现“机翼”和“壳”具有相似的膨胀速度（v exp = $ 115 $$ \ pm 5 $ km/s）。 “帽子”呈现残余的最低膨胀速度（v exp = $ 90 $$ \ pm 20 $ km/s），而“ shell”的上部呈现出最高的速度，相对于其余的残留物（v exp = $ 155 $$ \ pm 15 $ 15 $ km/s）。此外，整个星云的倾向相对于天空的平面和v sys的全身速度= -17 $$ \ pm 3 $ km/s。我们讨论了关于SNR的起源和演变的模型结果的解释，我们建议VRO 42.05.01与不均匀的环境介质具有相互作用的历史，这很可能是由于其祖细胞星的质量流出所影响的。
We present the first three dimensional (3D) Morpho-Kinematic (MK) model of a supernova remnant (SNR), using as a case study the Galactic SNR VRO 42.05.01. We employed the astrophysical code SHAPE in which wide field imaging and high resolution spectroscopic data were utilized, to reconstruct its 3D morphology and kinematics. We found that the remnant consists of three basic distinctive components that we call: a "shell", a "wing" and a "hat". With respect to their kinematical behaviour, we found that the "wing" and the "shell" have similar expansion velocities (V exp = $115$$\pm 5$ km/s). The "hat" presents the lowest expansion velocity of the remnant (V exp = $90$$\pm 20$ km/s), while the upper part of the "shell" presents the highest velocity with respect to the rest of the remnant (V exp = $155$$\pm 15$ km/s). Furthermore, the whole nebula has an inclination of ~$3°- 5°$ with respect to the plane of the sky and a systemic velocity of V sys = -$17$$\pm 3$ km/s . We discuss the interpretation of our model results regarding the origin and evolution of the SNR and we suggest that VRO 42.05.01 had an interaction history with an inhomogeneous ambient medium most likely shaped by the mass outflows of its progenitor star.
