Flux ratio of the [O I] λλ 6300,6364 line to the [Ca II] λλ 7294,7321 line as measured in the 445 d spectrum of SN 2023ixf (horizontal green line) in comparison to the ratios measured based on the model spectra of various progenitor masses from Dessart et al. (2021) (red circles) and Jerkstrand et al. (2014) (blue circles). This comparison favors a progenitor mass in the range of about 10–15 M⊙.
