Bolometric light curves of red-giant star collisions computed with CMFGEN. We include results for our set of eight models as well as those for the BSG explosion model a4 from Dessart & Hillier (2019) and the RSG explosion model X from Bostroem et al. (2023). We add the inferred values for SN 1987A (Hamuy et al. 1988). For the three faintest models, the CMFGEN light curve (thick line) is completed with the V1D results (thin line of the same color).
