A mechanism for the quasiperiodic decameter pulsations of the quiet sun
Abstract
The intensity fluctuations observed in the decameter-wavelength emission of the quiet sun can be interpreted by a plasma mechanism rather than by bremsstrahlung. The fluctuations would develop as the propagation of acoustic wave trains through the corona modulates the optical depth of the radio source.
