- Аннотация: Using the photoelectric 1981-1986 observations of RY Tau in the V band we have segregated brightness oscillations identified with the rotational modulation with a period of 7.25 d and an amplitude of 0.21 m in 1983-1984, and a period of 5.62 d, and an amplitude of 0.08 m in 1985-1986. The rotational modulation does not exceed 0.1 m in the amplitude in 1982-1983, 1984-1985 and probably was absent in 1981-1982. The difference of periods corresponding to the 1983-1984 and 1985-1986 seasons is evidence of the differential rotation.
