Abstract

The radiation field of a multi-dimensional plasma formation can be substantially asymmetrical. Often, the luminosity of such an object is determined using one-dimensional models with various correction factors to account for the nonsphericity. In this work, a model is presented for the determination of the luminosity of asymmetrical plasma formations based on consistent multi-dimensional radiation–hydrodynamics calculation on the example of the scenarios of supernovae with an equatorial disk. The simulations were compared with the observations of the supernova SN2009ip. The bolometric light curves were determined for the observation of this object in the disk plane and from the pole. A conclusion was made that it is impossible to describe the multi-dimensional structure of the radiation field within the framework of the one-dimensional model with correction factors and that, rather, a full three-dimensional simulation is required.

赤道盘存在时的非对称超新星情景的数值模拟
摘要多维等离子体形成的辐射场可能在很大程度上是不对称的。通常情况下,这种天体的光度是用一维模型来确定的,并用各种修正系数来考虑非球面性。在这项工作中,以带有赤道圆盘的超新星的情况为例,提出了一个基于一致的多维辐射流体力学计算的模型,用于确定不对称等离子体形成的光度。模拟结果与超新星 SN2009ip 的观测结果进行了比较。确定了在圆盘平面和从极点观测该天体的测光曲线。得出的结论是,在带有校正因子的一维模型框架内不可能描述辐射场的多维结构,而是需要进行全面的三维模拟。

期刊介绍: Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
