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…
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…
TESS light curves and period changes in low-mass eclipsing binary BB Persei
Marek Wolf, Petr Zasche, Miloslav Zejda +7
We present a detailed analysis of the low-mass detached eclipsing binary system BB Persei, which contains two K-type stars in a circular orbit with a short period of 0.4856 d. We u…
Apsidal motion and TESS light curves of three southern close eccentric eclipsing binaries: GM Nor, V397 Pup, and PT Vel
M. Wolf, P. Zasche, J. Kára +10
New ground-based and space-based photometric data have been obtained and archival spectroscopic measurements were used in this study of three detached early-type and southern-hemis…
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…
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…
Hen 3-860: New southern eclipsing symbiotic star observed in the outburst
J. Merc, R. Gális, M. Wolf +3
Brightening of Hen 3-860, previously classified as an H emitter, was detected by the ASAS-SN survey at the end of the year 2016. We have obtained the first spectroscopic observa…
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…
