Abstract:
BVR light curves of V343 Orionis were observed with the 85cm
telescope at Xinglong Station of the National Astronomical
Observatories of the Chinese Academy of Sciences, in 2007 and 2008.
Using the Wilson-Devinney program, the photometric solution of V343
Ori was first deduced from those observations. Photometric results
indicated that V343 Ori is an A-subtype W Ursae Majoris binary, whose
mass ratio and overcontact degree are q=0.253(±0.004) and
f=86.9%(±2.1%), respectively.
Description:
Photometric observations for V343 Ori were performed in 2007 December
and 2008 October, using the 85cm telescope at Xinglong Station of
National Astronomical Observatories of the Chinese Academy of Sciences
(NAOC).
