Synthetic profiles of {σ₋,σ₊} (color lines) and N (solid black line) in μHz for a 1 M_⊙ solar-type star (left) and a 12 M_⊙ massive star (right) for α = π/ 2, Θ = 5π/ 12, and various rotation rates: Ω = 0.1Ω_c (blue dotted-dashed line), 0.5Ω_c (green dashed line), 1Ω_c (red long-dashed line). The border between the convection and radiation zones (CZ and RZ) is given by the grey vertical line. For the 12 M_⊙ massive star, we filtered out the bumps of N at the top of the convective core and just below the stellar surface. In convection zones, σ₋ ~ N ~ 0.
