Complicated period changes in HQ Lyrae and DF Cygni.
BELSERENE E.P.
Abstract (from CDS):
The O-C diagrams of HQ Lyrae and DF Cygni cannot be described by equations of reasonably simple form. The sine curves which had statisfied limited stretches of data have failed to maintain their usefulness. A new linear ephemeris is given for HQ Lyrae.
