Abstract

The September 2012 outburst of the type IIn supernova 2009ip was simulated using two independent codes, STELLA and FRONT. The \(UBVRI\) light curves obtained agree well with one another and with observational data. Special attention is given to the dynamics of the emerging dense shell, which determines the luminosity of the object and is used for the direct method of determining the distance to the supernova. Two-dimensional spectral radiation-hydrodynamics computations of the SN 2009ip model were carried out, which confirmed the conclusion about the stability of this shell on the times scales of the method application.

2012b 超新星爆发 2009ip 的比较建模

摘要

使用两个独立的代码 STELLA 和 FRONT 模拟了 2012 年 9 月爆发的 IIn 型超新星 2009ip。获得的\(UBVRI\)光变曲线彼此吻合并且与观测数据吻合良好。特别关注新兴致密壳层的动力学，它决定了物体的光度，并用于确定超新星距离的直接方法。对SN 2009ip模型进行了二维光谱辐射-流体动力学计算，证实了该壳在方法应用的时间尺度上稳定性的结论。
