The first photometric solutions of the very short period (VSP) close binary DD Comae
Berenices (P= 0 fd 26920811) based on our new complete (IR) C light curves are derived by …

We present the first two sets of complete light curves in the R and I bands observed in 2011
and 2012 photometrically for the contact binary GSC 03526-01995. The asymmetric light …

YZ Phe is a very short-period contact binary (Sp.= K2 V) with an orbital period of 0.2347 d
near the short period limit (0.22 d). We present the complete light curves which photometric …

New CCD photometric light curves of the short-period (P= 0.285 d) eclipsing binary RW Dor
are presented. The observations were performed with the PROMPT-8 robotic telescope at …

In physiological conditions, proteases are essential in carrying out biological processes
such as gene expression, differentiation, and cell death. However, for their ability to degrade …

We present new photometry for three short-period contact binaries, GN Boo, BL Leo, and
V1918 Cyg, observed from 2008 December to 2012 April using several small telescopes in …

New CCD photometry for the eclipsing binary EH Cnc was made from 2009 to 2011, and five
new eclipsing times are presented. Through using the updated Wilson-Devinney code, we …

With new CCD observations of the W UMa type binary IK Boo, we present the first
investigation of photometric parameters and orbital period change. The BVR c light curve fit …

V1139 Cas, which is a very short period W UMa type binary star, was a neglected object
since its discovery. BVRI light curves of this system observed using the 1 m telescope at …

The first photometric analysis of V811 Cep was carried out. The first complete light curves of
V, R and I bands are given. The analysis was carried out by the Wilson-Devinney (WD) …
