Periodic Variations in Pulsar Radiation Intensity

Abstract

Power spectra of pulsar-intensity fluctuations at 318 MHz indicate that seven pulsars have line structure in their intensity spectra. Since two of these pulsars, AP 1237+25 and AP 2303+30 are newly discovered, their characteristic parameters are presented. The power spectra of CP 1919+21 and AP 2015+28 do not show features corresponding to the alias of the class 2 pulsation that is thought to cause subpulse structure
