Photometric study of three ultrashort-period contact binaries
L. Liu, S. -B., E. Fernandez Lajus +3
We carried out high-precision photometric observations of three eclipsing ultrashortperiod contact binaries (USPCBs). Theoretical models were fitted to the light-curves by means of…
A Photometric Study of Four Recently Discovered Contact Binaries: 1SWASP J064501.21+342154.9, 1SWASP J155822.10-025604.8, 1SWASP J212808.86+151622.0 and UCAC4 436-062932
G. Djurašević, A. Essam, O. Latković +4
We present new, high-quality multicolor observations of four recently discovered contact binaries: 1SWASP J064501.21+342154.9, 1SWASP J155822.10-025604.8, 1SWASP J212808.86+151622.…
The first photometric analysis of the W-subtype contact binary UCAC4 436-062932 with O'Connell effect
X. Zhou, S. -B. Qian, A. Essam +2
Two sets of light curves in bands for a newly discovered binary system UCAC4 436-062932 are obtained and analyzed using the Wilson-Devinney (W-D) code. The two sets…
OISTER Optical and Near-Infrared Observations of Type Iax Supernova 2012Z
Masayuki Yamanaka, Keiichi Maeda, Koji S. Kawabata +30
We report observations of the Type Iax supernova (SN Iax) 2012Z at optical and near-infrared wavelengths from immediately after the explosion until days after the maxi…
New CCD photometric observation of the W-UMa eclipsing binary system 1swasp j160156.04+202821.6
A. Essam, Nasser M. A
New BVRI light curves of the eclipsing binary system 1SWASP J160156.04+202821.6 have been obtained with the 1.88-m telescope of Kottamia Astronomical Observatory (KAO), Egypt on Ju…
Photometric Investigation of the Total-Eclipsing Contact Binary V12 in the Intermediate-age Open Cluster NGC 7789
S. -B. Qian, A. Essam, J. -J. Wang +3
NGC 7789 is an intermediate-age open cluster with an age that is similar to the mean age of contact binary stars. V12 is a bright UMa-type binary star with an orbital period of 0.3…
