Show affiliationsThe wave-energy spectra and fluxes for longitudinal tube waves generated in stellar convection zones are computed by using analytical methods developed in the two previous papers of this series. The main physical process responsible for the generation of these waves is the interaction between a thin and vertically oriented magnetic flux tube and the external turbulent convection. The spatial component of the turbulent convection is represented by an extended Kolmogorov turbulent energy spectrum, and its temporal component by a modified Gaussian frequency factor. The calculations are performed for Population I stars with effective temperatures ranging from Teff = 2000 K to 10,000 K, and with gravities log g = 3-5. The obtained results can be used to construct theoretical models of magnetic regions in stellar chromospheres.
