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…
The vanishing of the long photometric cycle in AU Monocerotis
L. Celedón, R. E. Mennickent, D. Barría +2
Double periodic variables (DPVs) are a group of semi-detached interacting binaries that exhibit a long photometric cycle with an average length of times the orbital period…
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…
Two black widow pulsars in the optical and X-rays
A. V. Bobakov, A. Yu. Kirichenko, S. V. Zharikov +5
Context. Two millisecond pulsars, PSR J15132550 and PSR J20171614, with spin periods of about 2.1 and 2.3 ms were recently discovered in the radio and -rays and classified…
Characterizing NGC 6383: A study of pre-main sequence stars, mass segregation, and age using Gaia DR3 and 2MASS
L. M. Pulgar-Escobar, N. A. Henríquez-Salgado, Pierluigi Cerulo +1
The presence of pre-main-sequence and low-mass stars, combined with the new data from Gaia DR3 and with 2MASS, significantly enhances the relevance of studying this cluster. We aim…
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…
