Long-term period variations of the SX Phoenicis star CY Aquarii.

POWELL J.P., JONER M.D. and McNAMARA D.H.

Abstract (from CDS):

New photoelectric times of maximum light of the SX Phoenicis variable CY Aquarii are combined with times of maximum light extending over 64 years to determine the long-term period variations. The recent data do not show significant cycle-to-cycle variations as some have reported but the data do clearly show an abrupt period change in 1989 corresponding to a new period of 0.061038645d.
