How is solar energy generated?

The solar interior is separated into four regions by the different processes that occur there. Energy is generated in the core, the innermost 25%. This energy diffuses outward by radiation (mostly gamma-rays and x-rays) through the radiative zone and by convective fluid flows (boiling motion) through the convection zone, the outermost 30%.

How does solar interior rotation affect helioseismic frequencies?

The rotation of the Sun''s interior introduces a ''rotational splitting'' of the helioseismic frequencies between modes of the same degree l and the azimuthal number m because waves propagate with and against the direction (prograde and retrograde). For a historical review of measurements of the solar interior rotation and its variation, see Howe (2009).
