Abstract:
New photoelectric BV and CCD BVR observations of the eclipsing contact binary
systems UV Lyn, FU Dra and AH Aur obtained from January 2000 to April 2001
are presented and analyzed. Photometric elements determined from our
light curves combined with published spectroscopic elements yielded
the absolute parameters of the systems. Analysis of the (O-C)
diagram of AH Aur revealed fast period changes. The correct ephemeris
for the primary minimum was determined. The evolutionary status of
all three systems is discussed.
