Solar oscillations interacting through a mean field
The “mean field” produced by the temperature and opacity fluctuations of the five minute modes in the sun is shown to change the temperature and density spatial structure of the linear 25 minute mode near the top of the photosphere. The effective medium, measured by the coefficients in the differential equation for the linear mode, can be altered by as much as 19 percent by the 5 minute mode “mean field,” indicative of possible nontrivial nonlinear processes in the photosphere.
