Cyclic light variations and accretion disk evolution in the LMC eclipsing binary OGLE-LMC-DPV-062
R. E. Mennickent, G. Djurašević, J. A. Rosales +4
Many intermediate-mass close binaries exhibit photometric cycles longer than their orbital periods, likely related to accretion-disk variability. Previous studies indicate that his…
Examining the brightness variability, accretion disk, and evolutionary stage of the binary OGLE-LMC-ECL-14413
R. E. Mennickent, G. Djurašević, J. A. Rosales +6
Our study aims to elucidate both short-term and long-term variations in the light curve of the eclipsing system OGLE-LMC-ECL-14413, with a particular focus on the unusual reversals…
V4142 Sgr: a Double Periodic Variable with an accretor surrounded by the accretion-disk's atmosphere
J. A. Rosales, R. E. Mennickent, G. Djurašević +4
Context: A detailed study of the close interacting binary V4142\,Sgr based on photometric and spectroscopic analysis is presented.This system belongs to the enigmatic class of Algo…
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 Double Periodic Variable Stars in the ASAS-SN Catalog
J. A. Rosales, R. E. Mennickent
We report the discovery of 3 new Double Periodic Variables based on the analysis of ASAS-SN light curves: GSD J11630570-510306, V593 Sco and TYC 6939-678-1. These systems have orbi…
Evolutionary process of the interacting binary V495 Centauri
J. A. Rosales, R. E. Mennickent, D. R. G. Schleicher +1
We present a simple model for the Double Periodic Variable (DPV) V495 Cen, which evolves as a binary system of intermediate mass, where the gainer cannot accrete at high rate, limi…
Dynamo effect in the double periodic variable DQ Velorum
R. I. San Martín-Pérez, D. R. G. Schleicher, R. E. Mennickent +1
DQ Velorum is a galactic double periodic variable (DPV), this system is a semi-detached binary comprised of a B-type gainer and an A-type donor star plus an extended accretion disc…
TYC 5353-1137-1: an enigmatic Double Periodic Variable of semiregular amplitude
J. A. Rosales, R. E Mennickent
We have performed a new search for DPVs of short period in the ASAS catalog (Pojmanski, G., 1997), focusing on those stars with orbital periods between 2 to 3 days which also show…
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…
