We show that the proper motion of a pulsating star results in a secular increase of the radial velocity of the star and consequently contributes to the observed . We found that this mechanism is very important in studying period changes in pulsating DA white dwarfs, where its effect is comparable with the expected evolutionary period change in these stars due to their cooling.
