标题： Radiative Transfer Modeling of Stripped-Envelope Supernovae. I: A Grid for Ejecta Parameter Inference

摘要： 我们展示了通过运行辐射传输代码Sedona并改变氦星前体的质量分布、速度剖面和丰度喷射剖面得到的1,800个多波长类型Ib/c超新星光变曲线模型。 为了创建一个灵活但物理上有依据的网格，我们使用自编码器来构建从恒星演化模型中得出的喷射剖面表示。 我们展示了对SN 1994I、SN 2007gr和iPTF13bvn的模拟最近邻多波段光变曲线匹配，以证明可以在我们的网格中生成现实的光变曲线。 我们表明，喷射速度分布尤其强烈影响光变曲线，而Ni-56的变化单独对光度光变曲线的影响有限，即使在极端和不合理的混合方案中也是如此；然而，混合可以适度影响颜色演化。 最后，我们表明可以从多波段光变曲线中推断出Ni-56质量、喷射质量以及喷射速度分布的幅度和结构，从而在广泛使用的半解析模型上实现改进的推断。 显示英文摘要

摘要： We present 1,800 multiwavelength Type Ib/c supernovae light curve models obtained by running the radiation transport code Sedona and varying the mass distribution, velocity profile, and abundance ejecta profiles of helium star progenitors. To create a flexible but physically-informed grid, we use autoencoders to construct a representation of ejecta profiles derived from stellar evolution models. We present simulated nearest-neighbor multiband light curves matches to SN 1994I, SN 2007gr, and iPTF13bvn to demonstrate that realistic light curves can be generated in our grid. We show that the ejecta velocity distribution, in particular, strongly influences the light curve, while variation in Ni-56 alone has a limited impact on the bolometric light curve, even in extreme and unphysical mixing schemes; however, mixing can modestly impact color evolution. Finally, we show that the Ni-56 mass, ejecta mass, and both the magnitude and structure of ejecta velocity distribution can be inferred from the multiband light curves, enabling improved inference over widely used semianalytical models.
