Photometric study of hot Algol-type binaries with long cycles
J. Garcés, R. E. Mennickent, J. Petrovíc +6
Double periodic variables (DPVs) are hot Algol-type interacting binary systems with an orbital and a long photometric cycle. The origin of the latter may be related to cyclic struc…
Photometric Analysis of Three Potential Red Nova Progenitors
Surjit S. Wadhwa, Ain De Horta, Miroslav D. Filipovic +4
We present photometric analysis of three bright red nova progenitor contact binary systems: ASAS J082151-0612.6, TYC 7281-269-1 and TYC 7275-1968-1. The primary components in all t…
Spectroscopy of the massive interacting binary UU Cassiopeiae
P. Hadrava, M. Cabezas, G. Djurašević +9
Context. The eclipsing close binary UU Cas is an interacting massive double-periodic system with a gainer star partly hidden in an accretion disk. Aims. In order to study the physi…
ZZ Piscis Austrinus (ZZ PsA): A bright red nova progenitor and the instability mass ratio of contact binary stars
Surjit S. Wadhwa, Ain De Horta, Miroslav D. Filipović +4
ZZ PsA is a neglected bright southern contact binary system with maximum V magnitude of 9.26. We present the first multi-band photometric analysis and find the system to be in deep…
Spectroscopic and photometric study of the eclipsing interacting binary V495 Centauri
J. A. Rosales, R. E. Mennickent, G. Djurašević +2
Double Periodic Variables (DPV) are among the new enigmas of semi-detached eclipsing binaries. These are intermediate-mass binaries characterized by a long photometric period lasti…
Doppler tomography of the Double Periodic Variable HD 170582 at low and high stage
R. E. Mennickent, S. Zharikov, M. Cabezas +1
HD170582 is an interacting binary of the Double Periodic Variable (DPV) type, showing ellipsoidal variability with a period of 16.87 days along with a long photometric cycle of 587…
Fundamental parameters of the close interacting binary HD170582 and its luminous accretion disc
R. E. Mennickent, G. Djurašević, M. Cabezas +5
We present a spectroscopic and photometric study of the Double Period Variable HD170582. Based on the study of the ASAS V-band light curve we determine an improved orbital period o…
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…
Physical parameters and evolutionary route for the LMC interacting binary OGLE 05155332-6925581
Hernán Garrido, Ronald E. Mennickent, Gojko Djuraŝevic +3
We analyze multicolor light curves and high resolution optical spectroscopy of the eclipsing binary and Double Periodic Variable OGLE 05155332-6925581. According to Mennickent et a…
A cyclic bipolar wind in the interacting binary V393 Scorpii
Ronald Mennickent, Zbigniew Kolaczkowski, Ewa Niemczura +4
V393 Scorpii is a Double Periodic Variable characterized by a relatively stable non-orbital photometric cycle of 253 days. Mennickent et al. argue for the presence of a massive opt…
