论文摘要
在本文中,我们介绍了为PS1-12CIL和SN 2012AA的光曲线(LCS)提供动力的能源储层的研究,这些曲线分别为极性和发光的超新星(SNE)。这两个SNE的多频段和降压LC在主要峰之后显示出异常的次要颠簸。两峰的LCS无法通过任何简单的能量源模型(例如$^{56} $ NI级联衰变模型,磁性旋转模型和Ejecta-Circumstellar Mediad Enteraction模型)来解释。因此,我们采用$^{56} $ ni Plus ejecta-circumstellar介质(CSM)互动(CSI)型号,Magnetar Plus CSI型号和双CSI模型来适合其砂型LCS,并发现这两个SNE都可以通过双CSI模型和Magnetar Plus CSI Plus CSI型号来解释这两个SNE。根据建模,我们计算了祖细胞驱逐壳的时间:只要它们是由双喷射壳CSI驱动的,内部和外壳可能会被驱逐出$ \ sim 0.2-3.6 $和$ \ sim 2-25 $,分别在SNE爆炸前分别在SNE爆炸前;如果SHES爆炸在SNE的爆炸爆炸之前,将壳被驱逐出$ \ sim $ \ sim,如果它们是由Magnetars Plus CSI供电的。
In this paper, we present the study for the energy reservoir powering the light curves (LCs) of PS1-12cil and SN 2012aa which are superluminous and luminous supernovae (SNe), respectively. The multi-band and bolometric LCs of these two SNe show unusual secondary bumps after the main peaks. The two-peaked LCs cannot be explained by any simple energy-source models (e.g., the $^{56}$Ni cascade decay model, the magnetar spin-down model, and the ejecta-circumstellar medium interaction model). Therefore, we employ the $^{56}$Ni plus ejecta-circumstellar medium (CSM) interaction (CSI) model, the magnetar plus CSI model, and the double CSI model to fit their bolometric LCs, and find that both these two SNe can be explained by the double CSI model and the magnetar plus CSI model. Based on the modeling, we calculate the the time when the shells were expelled by the progenitors: provided that they were powered by double ejecta-shell CSI, the inner and outer shells might be expelled $\sim 0.2-3.6$ and $\sim 2-25$ years before the explosions of the SNe, respectively; the shells were expelled $\sim 2-20$ years before the explosions of the SNe if they were powered by magnetars plus CSI.
