Terminal model matching the progenitor of SN 2016jbu from BPASS (Eldridge et al. 2017; Stanway & Eldridge 2018). Coloured markers are the primary star (M_TAMS = 17 M_⊙), assumed to be the progenitor of SN 2016jbu. The blue line is its binary companion (M_TAMS = 12 M_⊙). We note the evolutionary track for the companion has not reached core collapse, as the BPASS models terminate when the primary reaches the end of its life. The colour of the primary denotes its mass at each evolutionary time step, given in the colour bar. The inset shows a colour magnitude diagram, including the 2021 observations of SN 2016jbu (black marker) and the colour of the binary companion from the BPASS model during the last evolutionary time step (blue marker).
