摘要Many available published times of light minima of the active binary system UV Psc have been collected anti analyzed using a new method proposed by Kalimeris et al. (1994). Similar to what was seen in other RS CVn-type binaries, the orbital period of UV Pse oscillates with a period of about 61 years and an semi-amplitude of 0.21 x 10(-5) days. Two possible mechanisms (magnetic activity cycle mechanism and a light-lime effect due to a hypothetical third body) that could modulated the orbital period behaviour are studied. We think that the cyclical period change in UV Psc can most probably be attributed to a magnetic activity cycle in the primary component.
