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…
TIC 433545934: The first 2+2 type doubly eclipsing binary with extra, mutual eclipses
Tamás Borkovits, Saul A. Rappaport, Petr Zasche +5
In this work we identify and photodynamically analyze TIC 433545934, the very first doubly eclipsing 2+2-type quadruple stellar system, which shows outer eclipses, too. One such ou…
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…
