Six new doubly eclipsing quadruples in a 2+2 architecture
P. Zasche, H. Kucakova, J. Kara +5
The study presents a confirmation of six quadruples with two sets of eclipses that have the 2+2 architecture. These so-called doubly eclipsing systems still present a quite rare gr…
A study of transients from ground-based surveys reveals new ultra-compact accreting white dwarf binaries
Jan Kára, Liliana Rivera Sandoval, Wendy Mendoza +5
AM CVn stars are ultra-compact semi-detached binaries consisting of a white dwarf primary and a hydrogen-depleted secondary. In this paper we present spectroscopic and photometric…
Three new 2+2 quadruple systems with changing inclination
P. Zasche, Z. Henzl, M. Mašek +4
We present a unique discovery of three new detected systems showing two different phenomena together. These are 2+2 quadruple stellar systems showing two eclipsing binaries as the…
Eight new 2+2 doubly eclipsing quadruple systems detected
P. Zasche, Z. Henzl, J. Merc +2
We studied eight new doubly eclipsing stellar systems. We found that they are all rare examples of quadruple systems of 2 + 2 architecture, where both inner pairs are eclipsing bin…
Comprehensive analysis of a symbiotic candidate V503 Her
J. Merc, R. Gális, M. Wolf +10
V503 Her was previously proposed as an eclipsing symbiotic candidate based on photometric behavior and spectroscopic appearance indicating the composite optical spectrum. To invest…
Detection of seven 2+2 doubly eclipsing quadruple systems
P. Zasche, Z. Henzl, M. Masek +4
In this work, we study a heterogeneous group of seven stellar systems for the first time. Despite their different distances or spectral types, all of them belong to a very rare gro…
The Z Camelopardalis-type star AY Piscium: stellar and accretion disk parameters
Jan Kára, Sergey Zharikov, Marek Wolf +5
We present a new study of the Z~Cam-type eclipsing cataclysmic variable AY~Piscium with the aim of determining the fundamental parameters of the system and the structure of the acc…
A photometric study of NSVS 7453183: a probable quadruple system with long-term surface activity
L. Šmelcer, M. Wolf, H. Kučáková +5
The light curves were regularly measured for the eclipsing binary NSVS 7453183 as a part of our long-term observational project for studying of low-mass eclipsing binaries wi…
The first study of four doubly eclipsing systems
P. Zasche, Z. Henzl, J. Kara
We present the discovery and the very first analysis of four stellar systems showing two periods of eclipses, that are the objects classified as doubly eclipsing systems. Some of t…
The period-gap cataclysmic variable CzeV404 Her: A link between SW Sex and SU UMa systems
J. Kára, S. Zharikov, M. Wolf +4
Context: We present a new study of the eclipsing cataclysmic variable CzeV404 Her (Porb = 0.098 d) that is located in the period gap. Aims: This report determines the origin of the…
Possible substellar companions in dwarf eclipsing binaries: SDSS J143547.87+373338.5, NSVS 7826147, and NSVS 14256825
M. Wolf, H. Kučáková, P. Zasche +4
We present the new results of our long-term observational project to detect the small variations in the orbital periods of low-mass and short-period eclipsing binaries. About 120 n…
First apsidal motion and light curve analysis of 162 eccentric eclipsing binaries from LMC
P. Zasche, M. Wolf, H. Kučáková +6
We present an extensive study of 162 early-type binary systems located in the LMC galaxy that show apsidal motion and have never been studied before. For the ample systems, we perf…
