3. Solar Oscillations Theoretical Implications of Observations
Part of the Lecture Notes in Physics book series (LNP, volume 125)


The interpretation by Hill and Caudell (1979) of some of their solar oscillation data as being due to g modes of degree greater than 20 seems to imply that the solar convection zone is much shallower than that in standard solar models, probably representing only a few per cent of the radius. We attempt here to match the observed periods in models of this nature; the rather complicated spectrum of oscillations in such models can be understood in terms of the asymptotic behavior of modes of large degree. Possible excitation mechanisms for the modes are briefly discussed.
