Individual Pulses Behaviour of PSR B0950+08 at 111 MHz

Abstract


We carried out an analysis of the behaviour of individual pulses of PSR B0950+08 based on our observations at a frequency 111.2 MHz. The intensity and phase distribution of pulses at different longitudes of the pulsar average profile was investigated. The intensity of individual pulses can exceed ten times the average profile amplitude. It was shown that the intensity distribution of weak pulses with longitude of their appearance differs strongly from the distribution of strong pulses. The flux density of the average pulse changes by a factor of up to 13 from day to day, due to interstellar scintillation. It was shown that the cumulative distribution function is described by a polynomial fit of the second order in log-log scale.
