Abstract:
We present new multicolor photometry for RZ Draconis, observed in 2009
at the Xinglong Station of the National Astronomical Observatories of
China. By using the updated version of the Wilson-Devinney Code, the
photometric-spectroscopic elements were deduced from new photometric
observations and published radial velocity data.
Description:
New photometry of RZ Dra was carried out on 2009 June 28, 29, 30, and
October 6, using the 85cm telescope at the Xinglong Station of the
National Astronomical Observatories of China (NAOC).
The standard Johnson-Cousin-Bessel BVRI multicolor CCD photometric
system was equipped on the primary focus of this telescope.
