From left to right, maps of the growth rate, ω_i, frequency, ω_r, azimuthal number, m, and corotation radius of the most unstable fundamental mode with three dissociation rates: ε = 0 (top row), 0.3 (middle row), and 0.5 (bottom row). Above the dashed magenta line, the growth rate of equatorial perturbations decreases with rotation. In the two left columns, the white lines show where the corotation radius equals r_PNS and r_gain. In the two right columns, the black lines highlight the variation in the dominant azimuthal number, m. The numbers in the third and fourth columns highlight the azimuthal number of the most unstable mode.
