Abstract:
We present the first multiband photometry for the semidetached
eclipsing binary AO Serpentis, observed on seven nights between 2009
April and July at the Weihai Observatory of Shandong University. By
using the 2003 version of the Wilson-Devinney code, the photometric
solutions of AO Ser and a similar object V338 Her were (re)deduced.
The spectral types and orbital periods are A2 and P=0.8793-days for
AO Ser, F1V and P=1.3057-days for V338 Her.
Description:
Charge-coupled device (CCD) photometry for the Algol-type eclipsing
binary AO Ser was carried out from April to July in 2009, using the
1.0 m Cassegrain telescope at the Weihai Observatory of Shandong
University in China. A back-illuminated PIXIS CCD camera from the
Princeton Instruments company was mounted at the Cassegrain focal
plane of this telescope.
Photometric observations of AO Ser were obtained on 2009 April 4, 6,
7, 9, and 10, June 23, and July 1.
