V894 Cygni: analysis and interpretation of variability.

FAHN J.D.

Abstract (from CDS):

New elements for a constant period, as well as for a possible changing period, are given for the RR Lyrae (ab) star V894 Cygni. Linear elements are JD(max) = 2445650.561 + 0.57138542 E ±0.0011 ±0.00000008 Parabolic elements are: JD(max) = 2445650.566 + 0.57138667 E + 5.7 x 10e-11 E^2 ±0.004 ±0.00000072 ±2.0 x 10e-11
