论文摘要
在2012年Supernova 2009IP的两次爆发中提出了球形和非球体模型。模型是基于一种情况，表明2012年8月爆发是由LBV-Presupernova的爆炸性外壳弹射引起的。该模型预测2012年7月下旬未观察到的爆发的出现与冲击突破以及随后的弹射信封的扩散辐射冷却。 2012年8月，首次观察到的爆发的亮度大概是由中央来源提供动力的，而第二次，更强大的爆发是2012年9月下旬是由与情节信封的射流互动引起的。模型提供了喷射能量和质量以及壳外壳的质量的估计。
Spherical and aspherical models are presented for two outbursts in 2012 of supernova 2009ip. Models are based on a scenario which suggests that the August 2012 outburst is caused by the explosive shell ejection from LBV-presupernova. The model predicts an emergence of an unobserved outburst in late July 2012 related to a shock breakout and a subsequent diffusive radiative cooling of the ejected envelope. The luminosity of the first observed outburst in August 2012 was presumably powered by the central source, whereas the second, more powerful outburst in late September 2012, was caused by the ejecta interaction with the circumstellar envelope. Models provide estimates of the ejecta energy and mass along with the mass of the circumstellar shell.
