Abstract:
New differential UBV photoelectric photometry for the eclipsing binary
AY Cam is presented. The Wilson-Devinney program is used to
simultaneously solve the three light curves together with previously
published radial velocities.
Description:
Differential UBV measurements of AY Cam (BD+77 328, SAO 6527)
were collected primarily during the 1976-1977 observing season, with a
few additional nights in 1978 and 1981. The observations were made
with an unrefrigerated EMI 6256S photomultiplier on the 0.9m telescope
at the Fernbank Science Center (Atlanta, Georgia).
