Solar Convection.
Abstract
A thorough study of convective penetration into the solar atmosphere and convective motions in sub-atmospheric layers on the sun was made. Non-linear anelastic and Boussinesq modal equations were developed and solved to describe solar and stellar convection. An explanation was developed for the lack of penetration of large-scale convective motions into the observable solar atmosphere through the discovery of buoyancy braking near the top of a supposedly unstable layer. Observations of motions in the solar atmosphere led to the discovery of a new scale of solar motion, the so-called mesogranulation. A technique was developed to use changes in the solar five-minute oscillations as a probe of internal solar structure. Using this technique, large-scale, subatmospheric convective eddies were discovered.
