Solar Activity and the Coupling of g-Mode Oscillations
Abstract
The solar g-mode oscillations depend strongly on the difference between actual and adiabatic temperature gradients in the solar interior. Solar activity anchored at the base of the convection zone disturbs this difference and couples modes with similar eigenfrequencies. The author computes this coupling and discusses the possible observational effects at the photosphere. These include a scatter in the frequencies deduced for weakly coupled modes and the apparent temporal behavior of strongly coupled modes.
