| Abstract: |
We observed the active binary XY UMa by using 40cm telescope and
CCD camera of Canakkale Observatory, 1m telescope and CCD camera
of Yunnan Observatory in 2004 and 2005. The obtained BVRI
photometric light curves are analyzed by means of Wilson-Devinney
code, and the starspot parameters are derived for the system. The
results demonstrate that the main spots are located in the medium
latitude regions during our observing runs. Finally, we have
discussed the spot evolution from 2004 to 2005. |
