Mechanisms for pulsar eclipse

Research output: Contribution to journalArticlepeer-review

The steady (DC) component of the 318 MHz emission of pulsar 1957 + 20 appears to be eclipsed by plasma that is too tenuous for a plasma frequency cutoff. Alternative eclipse mechanisms are considered, including (1) scattering by plasma turbulence, (2) nonlinear decay of electromagnetic waves, and (3) absorption by non-thermal electrons. Several possible observational consequences are discussed.
