A Study of Twelve Potential Merger Candidate Contact Binary Systems
Surjit S. Wadhwa, Bojan Arbutina, Nick F. H. Tothill +4
Photometric observations and analysis of twelve previously poorly studied contact binary systems is presented. All show total eclipses and have extremely low mass ratios ranging fr…
Simplified Method for the Identification of Low Mass Ratio Contact Binary Systems that are Potential Red Nova Progenitors
Surjit S. Wadhwa, Ain Y. De Horta, Miroslav D. Filipovic +4
The study presents a simplified method to identify potential bright red nova progenitors based on the amplitude of the light curve and infrared (J-H) colour of a contact binary sys…
Fundamental parameters of the eclipsing binary DD CMa and evidence for mass exchange
J. A. Rosales, R. E. Mennickent, G. Djurašević +5
We present a detailed photometric and spectroscopic analysis of DD CMa, based on published survey photometry and new spectroscopic data. We find an improved orbital period of $P_\m…
Stellar and accretion disk parameters of the close binary HD 50526
J. A. Rosales, R. E. Mennickent, G. Djurašević +5
We present a photometric and spectroscopic study of HD 50526, an ellipsoidal binary member of the group Double Periodic Variable stars. Performing data-mining in photometric survey…
New insights on the massive interacting binary UU Cassiopeiae
R. E. Mennickent, G. Djurašević, I. Vince +7
We present the results of the study of the close binary UU Cassiopeiae based on previously published multi wavelength photometric and spectroscopic data. Based on eclipse timings o…
Long photometric cycle and disk evolution in the Lyrae type binary OGLE-BLG-ECL-157529
R. E. Mennickent, J. Garcés, G. Djurašević +4
The subtype of hot algol semidetached binaries dubbed Double Periodic Variables (DPVs) are characterized by a photometric cycle longer than the orbital one, whose nature has been r…
On the long cycle variability of the Algol OGLE-LMC-DPV-065 and its stellar, orbital and disk parameters
R. E. Mennickent, M. Cabezas, G. Djurašević +13
OGLE-LMC-DPV-065 is an interacting binary whose double-hump long photometric cycle remains hitherto unexplained. We analyze photometric time series available in archive datasets sp…
Long-term Spot Stability in the Post-common-envelope Binary QS Vir
Olivera Latković, Attila Cséki, Gojko Djurašević +3
We observed the post-common-envelope eclipsing binary with a white dwarf component, QS Vir, using the 1.88 m telescope of Kotammia Observatory in Egypt. The new observations were a…
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.…
On the eclipsing binary ELHC 10 with occulting dark disc in the Large Magellanic Cloud
H. E. Garrido, R. E. Mennickent, G. Djurasevic +4
We investigate the luminous star ELHC 10 located in the bar of the Large Magellanic Cloud, concluding that it is a SB1 long-period eclipsing binary where the main eclipse is produc…
Photometric analysis of overcontact binaries AK Her, HI Dra, V1128 Tau and V2612 Oph
S. Caliskan, O. Latkovic, G. Djurasevic +7
We analyze new, high quality multicolor light curves of four overcontact binaries: AK Her, HI Dra, V1128 Tau and V2612 Oph, and determine their orbital and physical parameters usin…
On the accretion disc and evolutionary stage of beta Lyrae
R. E. Mennickent, G. Djurašević
We modeled the V-band light curve of beta Lyrae with two stellar components plus an optically thick accretion disc around the gainer assuming a semidetached configuration. We prese…
The evolution stage and massive disc of the interacting binary V393 Scorpii
R. E. Mennickent, G. Djurasevic, Z. Kolaczkowski +1
V393 Scorpii is a bright Galactic Double Periodic Variable showing a long photometric cycle of approx. 253 days. We present new VIJK photometric time series for V393 Scorpii along…

Accretion disk in the eclipsing binary AU Mon
G. Djurasevic, O. Latkovic, I. Vince +1
We analyze the CoRoT and V-passband ground-based light curves of the interacting close binary AU Mon, assuming that there is a geometrically and optically thick accretion disk arou…
The interacting binary V 393 Scorpii: another clue for Double Periodic Variables
Ronald Mennickent, Zbigniew Kolaczkowski, Gojko Djurasevic +2
We give a brief report on spectroscopic properties of V 393 Scorpii. H alfa emission and shape and radial velocity of He I 5875 are modulated with the long cycle. The long cycle is…
