The first 3D Morpho-kinematical model of a Supernova Remnant: The case of VRO 42.05.01 (G 166.0+4.3) (1909.06131v1)

Abstract: 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.
