Left: spectrum of the IGW luminosity generated by the convective Reynolds stresses of the envelope for various frequencies σ and degrees ℓ. Middle: spectrum of the IGW luminosity at 0.05 R_⊙ below the convective envelope for retrograde (left) and prograde (right) waves with various frequencies and degrees ℓ. Only the cases with m = ℓ (top) and m = 1 (bottom) are shown. Right: spectrum of the net luminosity at 0.05 R_⊙ below the convective envelope for various frequencies and degrees ℓ (and m).
