Abstract
The effect of the source motion on the period variation of pulsars is investigated. For some pulsars, a velocity 100–300 km/s can give a Doppler contribution to the second period derivative P which is comparable or larger than the intrinsic variation predicted by theoretical models, whereas larger velocities are required in order to give an appreciable kinematic effect on the first derivative P. The possibility of experimental detection of P and proper motion for known pulsars is discussed.
