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.

超新星 2009ip 的 2012b 爆发对比模型

摘要利用STELLA和FRONT两个独立的代码模拟了2012年9月IIn型超新星2009ip的爆发。得到的（UBVRI/）光曲与观测数据相互吻合。特别关注了新出现的致密壳的动力学，它决定了天体的光度，并被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力学计算，结果证实了这一外壳在方法应用的时间尺度上的稳定性。
