论文摘要
源自恒星爆炸的许多天体瞬变是由弹出材料与折线介质的碰撞的动力，这些材料通过冲击消散有效地产生热辐射。我们研究了这种相互作用驱动的瞬变是如何分布在峰值辐射光度与上升时间相空间中的。利用球形对称性较少的耗时的一维模拟，我们计算了500多个模型，具有不同的间隙质量和半径，弹出质量和能量以及化学组成。对于每种模拟的光曲线，测量了峰值降压光度的光度，总辐射能和相互作用驱动发射的上升时间。我们考虑如何确定这些特征数量是模型参数的函数，并讨论对（潜在）相互作用供电的瞬变（例如IIN型超新星和快速蓝色光学瞬变）的观察到的含义。
A number of astrophyical transients originating from stellar explosions are powered by the collision of the ejected material with the circumstellar medium, which efficiently produces thermal radiation via shock dissipation. We investigate how such interaction-powered transients are distributed in the peak bolometric luminosity vs the rise time phase space. Taking the advantage of less time-consuming one-dimensional simulations with spherical symmetry, we calculated more than 500 models with different circumstellar mass and radius, ejecta mass and energy, and chemical compositions. The peak bolometric luminosity, the total radiated energy, and the rise time of the interaction-powered emission are measured for each simulated light curve. We consider how these characteristic quantities are determined as a function of the model parameters and discuss possible implications for the observed populations of (potential) interaction-powered transients, such as type IIn supernovae and fast blue optical transients.
