Bolometric Corrections for optical light curves of Core-collapse Supernovae

Abstract: Through the creation of spectral energy distributions for well-observed literature core-collapse supernovae (CCSNe), we present corrections to transform optical light curves to full bolometric light curves. These corrections take the form of parabolic fits to optical colours, with $B - I$ and $g - r$ presented as exemplary fits, while parameters for fits to other colours are also given. We find evolution of the corrections with colour to be extremely homogeneous across CCSNe of all types in the majority of cases, and also present fits for stripped-envelope and type II SNe separately. A separate fit, appropriate for SNe exhibiting strong emission due to cooling after shock breakout, is presented. Such a method will homogenise the creation of bolometric light curves for CCSNe where observations cannot constrain the emitted flux - of particular importance for current and future SN surveys where typical follow-up of the vast majority of events will occur only in the optical window, resulting in consistent comparisons of modelling involving bolometric light curves. Test cases for SNe 1987A and 2009jf using the method presented here are shown, and the bolometric light curves are recovered with excellent accuracy in each case.
