The drifting sub-pulse phenomenon in PSR 0809+74
Abstract
PSR 0809 + 74 has been observed simultaneously at 8i MHz and 151 Mllz in order to study drifting sub-pulses and the effects of pulse nulling. It is found that drifting sub-pulse bands are generated with a periodicity which is stable to at least I part in I o when allowance is taken of a characteristic jump of sub-pulse phase associated with nulls. The overall behaviour is similar at both frequencies, apart from an increased sub-pulse width at I 51 Milz, although the mean pulse envelope is substantially broader at 8i . The relevance of these observations to pulsar models is briefly discussed.
