Abstract:
We present CCD photometry for the Algol-type binary RV Trianguli
observed during three nights in 2007 November. The photometric
solution was derived from our VR observations by using the
Wilson-Devinny program. The results indicated that RV Tri is a
semidetached binary with a mass ratio of q=0.306±0.005. Based
on 236 light minimum times, the orbital period change of RV Tri was
analyzed in detail.
Description:
CCD observations of RV Tri were carried out in 2007 November 28-30,
using the 85 cm telescope at the Xinglong Station of National
Astronomical Observatories of the Chinese Academy of Sciences.
