The EBV antibodies were measured in 378 sera from a group of 129 pediatric and older cases
of infectious mononucleosis and from 117 family and social contacts. Cases of infectious …

… In order to analyze the periodic variations of VW Cep, we constructed the O–C diagram of
the system. For this purpose, we downloaded all the minima times from the O–C gateway …

In this work we report the discovery and analysis of three new triply eclipsing triple star
systems found with the TESS mission during its observations of the northern skies: TICs …

We report the discovery of a compact triply eclipsing triple star system in the southern continuous
viewing zone of the TESS space telescope. TIC 278825952 is a previously known, but …

We report the discovery in TESS Sectors 3 and 4 of a compact triply eclipsing triple star
system. TIC 209409435 is a previously unknown eclipsing binary with a period of 5.717 d, and …

We report the discovery and complex analyses of the first two compact hierarchical triple star
systems discovered with TESS in or near its southern continuous viewing zone during Year …

Aims. We introduce a novel way to identify new compact hierarchical triple stars by exploiting
the huge potential of Gaia DR3 and also its future data releases. We aim to increase the …

In this work, we report the discovery and analysis of six new compact triply eclipsing triple star
systems found with the TESS mission: TICs 37743815, 42565581, 54060695, 178010808, …

In this work, we report the independent discovery and analysis of nine new compact triply
eclipsing triple star systems found with the Transiting Exoplanet Survey Satellite (TESS) …

Context. Studying chromospheric activity of contact binaries is an effective way of revealing
the magnetic activity processes of these systems. One efficient but somewhat neglected …
