论文摘要
在这项工作中,我们使用两种公开分析工具来研究四个氢(H) - 剥离的核心超新星(CCSNE),即SN 2009JF,IPTF13BVN,SN 2015AP和SN 2016BAU。我们使用模块化的开源钳工进行瞬变({\ tt Mosfit})来对多条带光曲线进行建模。 {\ tt mosfit}分析显示$ 0.80 _ { - 0.13}^{+0.18} $ 0.18} $ m $ _ {\ odot} $,$ 0.15 _ {+0.15 _ { - 0.15 _ { - 0.09} $ 0.13}^{+0.13} $ $ 0.13}^{+0.13} $ 0.13}^{+0.13} $ 0.13}^{ - 0.13} $ _} $ 0.19 _ { - 0.03}^{+0.03} $ m $ _ {\ odot} $,$ 0.19 _ {+0.02}^{ - 0.01} $ 0.01} $ M $ _ {\ odot} $ for Sn 2009Jf,iptf13vn,iptf13vn,sn 2015ap,and SN 2016AU,以及后来,用于恒星天体物理学实验的模块({\ tt Mesa}),用于构建从序列序列的恒星模型,直至核心塌陷,以作为这些H型CCSNE的可能的祖细胞。基于文献,我们建模了12 m $ _ {\ odot} $ ZAMS Star作为IPTF13VN,SN 2015AP和SN 2016BAU的可能祖细胞,而20 m $ _ {\ odot} $ ZAMS Star的模型是SN 2009JF的祖先。已经介绍了恒星工程的一瞥及其生命周期各个阶段模型的物理特性,以证明这些分析线程的有用性,以了解几类瞬态的观察到的属性。
In this work, we employ two publicly available analysis tools to study four hydrogen(H)--stripped core--collapse supernovae (CCSNe) namely, SN 2009jf, iPTF13bvn, SN 2015ap, and SN 2016bau. We use the Modular Open-Source Fitter for Transients ({\tt MOSFiT}) to model the multi band light curves. {\tt MOSFiT} analyses show ejecta masses (log M$_{ej}$) of $0.80_{-0.13}^{+0.18}$ M$_{\odot}$, $0.15_{-0.09}^{+0.13}$ M$_{\odot}$, $0.19_{-0.03}^{+0.03}$ M$_{\odot}$, and $0.19_{+0.02}^{-0.01}$ M$_{\odot}$ for SN 2009jf, iPTF13vn, SN 2015ap, and SN 2016au, respectively. Later, Modules for Experiments in Stellar Astrophysics ({\tt MESA}), is used to construct models of stars from pre-main sequence upto core collapse which serve as the possible progenitors of these H-stripped CCSNe. Based on literature, we model a 12 M$_{\odot}$ ZAMS star as the possible progenitor for iPTF13vn, SN 2015ap, and SN 2016bau while a 20 M$_{\odot}$ ZAMS star is modeled as the possible progenitor for SN 2009jf. Glimpses of stellar engineering and the physical properties of models at various stages of their lifetime have been presented to demonstrate the usefulness of these analysis threads to understand the observed properties of several classes of transients in detail.
