R. Abstract Phase residuals in O-C diagrams for the classical Cepheid AW Persei have been examined to see whether they produce periodic variations associated with binary orbital motion (the light-time effect). Variations of several standard deviations in the O-C diagram are consistent with a light-time interpretation. The available radial velocity information is in agreement with the size and timing of the light curve shifts. An orbital period of 20 years is derived from recent radial velocities. Mass estimates from the orbit are discussed.
