Period spacing patterns (PSPs) for (ℓ, m)=(1, ±1) and (ℓ, m)=(2, ±2) g modes with rotation rates of Ω/Ω_c=0.10−0.30 (panels a–d) and Ω/Ω_c=0.40−0.60 (panels e–h) for the 16.9 M_⊙ 3D MHD merger product and the 17.4 M_⊙ genuine single star at X_{c, merger}=0.50 and X_{c, single}=0.51, respectively. The black, blue, and grey lines with dot markers correspond to the merger product's PSPs, while the red, orange, and gold lines with cross markers correspond to the PSPs of the genuine single star. The PSPs are shown in the inertial (observer's) frame.
