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…
