Analyses of Hydrogen-stripped core-collapse supernovae using MOSFiT and MESA based tools

Abstract

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.
