The influence of the Reynolds stress on the solar p-mode frequencies

We examine the influence of the Reynolds stress as the main contribution of turbulence on the oscillation frequencies of the solar p-modes. We regard the radial oscillations as well as the nonradial ones in order to study the influence depending on the degree l of the modes. For the radial modes we find that the influence of the turbulence gives cor rections that reduce significantly the difference between observed and theo retical calculated frequencies. Regarding the nonradial modes we find, addi tionally, an increase in the corrections with the harmonic degree l which i s in good agreement with the observations. We consider turbulent corrections appearing in the oscillation equations as well as the changes of the model itself for consistency. For radial and no nradial modes we find that the changes of the model are of minor importance compared to the turbulence terms appearing directly in the equations of th e oscillation.
