Coherent Amplification and Pulsar Phenomena
Abstract
A modification of the rotating-star model has been developed to interpret the periodic energy bursts from pulsars. This new configuration involves θ-directed oscilltion modes in the stellar atmosphere or magnetosphere, and most aspects of the typical pulse characteristics are well accounted for. Gain is provided by resonant interactions with particles trapped in the stellar magnetic field. The most significant feature is the fact that highly directional beaming of the output energy results as a natural consequence of coherence between the radiation fields emerging from various locations about the pulsar; and a localized radiation origin is not required.
