Excitation of stellar radial pulsation by nonradial modes

OSTI ID:5111070
The space-averaged equation of radial motion is considered for a star executing nonradial oscillations. These oscillations may serve as a time-variable external force driving radial pulsations. The process will be most efficient if the nonradial modes include pairs (having the same azimuthal number) with frequencies whose sum or difference is close to the radial-pulsation frequency. In this event radial pulsations will tend to be excited with nearly equal frequencies.
