Abstract

Differential photometry of the RS CVn-type binary 54 Cam in 1978, 1979, and 1980 shows its light to be variable with a period of 10 d. 163±0 d. 009 and an amplitude inV (max. to min.) which increased from 0 m. 03 to 0 m. 06 between 1979.19 and 1980.82. An epoch of light minimum was JD 2444529.7. The 9% difference betweenP(phtm.)=10 d. 163 andP(orb.)=11 d. 0764,a much larger difference than is characteristic of other RS CVn binaries, is suggested as an explanation for the radio emission.
