论文摘要
我们对旨在解释SN 2016AP的大规模室外培养基(CSM)进行了一维辐射流动力学模拟,该模拟与大规模的室内培养基(CSM)相撞,这可能是迄今为止观察到的最明亮的超新星。 SN 2016APS是一种超小型IIN SN,可发行高达$ \ gtrsim 5 \ times 10^{51} $ thyth photer辐射。我们的结果表明,SN 2016AP的多波段光曲线通过$ 30 \ m_ \ odot $ sn ejecta的碰撞与$ 10^{52} $ erg的爆炸能量和$ \ simeq 8 \ \ m_ \ m_ \ m_ \ odot $ wind-like csm csm after the the Outerad radius,$ 10^$ 10^16} 16} 16} I.嵌入大量的CSM中。这一发现表明,最初质量的非常大的恒星大于$ 40 \ m_ \ odot $,据说它会产生高能量的SNE,偶尔在核心爆发前不久会弹出其氢富含氢的信封。我们建议脉冲配对稳定性SNE可以为大规模的CSM和能量爆炸提供自然的解释。我们还提供了峰值光度,辐射能量和与$ 10^{52} $ erg相互作用的sne相互作用的上升时间之间的关系,该能量可用于解释未来调查中SN 2016APS样品。
We perform one-dimensional radiation-hydrodynamic simulations of energetic supernova ejecta colliding with a massive circumstellar medium (CSM) aiming at explaining SN 2016aps, likely the brightest supernova observed to date. SN 2016aps was a superluminous Type-IIn SN, which released as much as $\gtrsim 5\times 10^{51}$ erg of thermal radiation. Our results suggest that the multi-band light curve of SN 2016aps is well explained by the collision of a $30\ M_\odot$ SN ejecta with the explosion energy of $10^{52}$ erg and a $\simeq 8\ M_\odot$ wind-like CSM with the outer radius of $10^{16}$ cm, i.e., a hypernova explosion embedded in a massive CSM. This finding indicates that very massive stars with initial masses larger than $40\ M_\odot$, which supposedly produce highly energetic SNe, occasionally eject their hydrogen-rich envelopes shortly before the core-collapse. We suggest that the pulsational pair-instability SNe may provide a natural explanation for the massive CSM and the energetic explosion. We also provide the relations between the peak luminosity, the radiated energy, and the rise time for interacting SNe with the kinetic energy of $10^{52}$ erg, which can be used for interpreting SN 2016aps-like objects in future surveys.
