  We examine the acoustic and magnetic energy generation and propagation in
beta Hydri (G2 IV). The underlying motivation for this work is based on the
solar, stellar, and galactic relevance of beta Hydri (a star in the Southern
hemisphere), which is readily understood as a prime example and proxy of the
future Sun - thus allowing assessments and analyses of the secular decay of
solar activity. Regarding the magnetic energy generation, we consider
longitudinal flux tube waves. We also assess acoustic waves. For the acoustic
wave energy flux, the difference between the results obtained for beta Hydri
and the Sun is significantly smaller than typically attained for main-sequence
stars, which is largely due to the gravity-dependence of the acoustic energy
generation. Furthermore, we study the height-dependent behavior of the magnetic
energy flux for different magnetic filling factors corresponding to different
flux tube spreadings. Finally, we comment on possible directions of future
research.
