Different parameters influencing the angular momentum luminosity carried by stochastically excited gravity waves (Eq. 10) as a function of stellar age for a M_ZAMS = 1 M_⊙ star. Shown are the changes in: the radius of the radiative–convective boundary (solid blue), density (solid orange), convective timescale (dashed green), convective velocity (dashed red), Brunt-Väisälä frequency (dash-dotted purple), and Brunt-Väisälä frequency squared (dash-dotted brown) at the radiative-convective boundary. Stellar evolutionary phases (pre-MS to WD) are indicated.
