Caption: Figure 14.
Left: optical spectra of SN 2024iss compared with 2p90 (Menv = 0.28 M⊙) optical model spectra at similar phases from L. Dessart et al. (2024). The δt = 7 days HST spectrum is shown in red. Right: the full HST UV-to-NIR δt = 7 days spectrum of SN 2024iss compared to a range of model spectra (2p80: Menv = 0.12 M⊙; 2p85: Menv = 0.19 M⊙; 2p90: Menv = 0.28 M⊙; 2p95: Menv = 0.31 M⊙) at similar phases from L. Dessart et al. (2024).
