Total CO and SiO masses and masses formed per region as a function of time for the standard case case and available observations for various Type II SNe. Top: CO, where the brown empty square is SN2017eaw (Rho et al. 2018; Tinyanont et al. 2019), fuschia empty triangle is SN2023ixf (Park et al. 2025), dark blue empty square is SN1987A (Spyromilio et al. 1988), green empty circle and orange empty rhombus are SN1987A for the LTE and NLTE case, respectively (Liu et al. 1992), pink circle is SN2024ggi (Mera et al. 2026). Bottom: SiO, where the dark grey empty rhombus is SN2005af (Kotak et al. 2006), green empty circle is SN1987A for NLTE (Liu & Dalgarno 1994), lavender cross is SN2004et (Kotak et al. 2009), pink triangle is SN2024ggi (Mera et al. 2026). Value ranges for both CO and SiO derived from ALMA data of SN1987A by Matsuura et al. (2017) are also indicated with filled grey rectangles.
