| Abstract: | The influence of chromospheric magnetism on p- and f-modes is examined. The magnetism is modelled as a horizontal canopy field, embedded in an isothermal atmosphere, overlying a field-free polytropic convection zone. Both low and high frequency modes are considered. The recently detected solar cycle variability of p-modes is explored from the view-point of this model. The dual influence of convective motions and magnetism on the f-mode is discussed. |
