Abstract:
We present B-, V-, and I-band CCD photometry of the W UMa-type binary
system TX Cnc, which is a member star of the Praesepe open cluster.
Based on the observations, new ephemeris and a revised photometric
solution of the binary system were derived.
Description:
The star was observed on four nights from 2008 February 25 to 2008
February 28 using the 85cm reflector at the Xinglong Station of the
National Astronomical Observatories, Chinese Academy of Sciences.
