Abstract:
We present charge-coupled device (CCD) photometry for the short-period
K-type binary EI CVn, observed on 2009 February 28 at the Xinglong
Station of National Astronomical Observatories, Chinese Academy of
Sciences. By using the Wilson-Devinney program, the photometric
solution was first deduced from our VR observations.
Description:
New Photometry of EI CVn was carried out on 2009 February 28 using the
60-cm telescope at the Xinglong Station of the National Astronomical
Observatories, Chinese Academy of Sciences (NAOC). The photometer was
equipped with a 1024x1024 pixel CCD camera. Each pixel subtends a
projected angle on the sky of 0.996", which results in a field of view
of 17'x17'.
