Starspots on eclipsing giant stars I.: The sample and eclipse mapping examples
K. Oláh, B. Seli, A. Haris +12
Spotted stars in eclipsing binary systems allow us to gather significant information about the stellar surface inhomogeneities that is otherwise impossible from only photometric da…
The Discovery of Two Quadruple Star Systems with the Second and Third Shortest Outer Periods

We present the discovery of two quadruple star systems -- TIC 285853156 and TIC 392229331 -- each consisting of two bound eclipsing binary stars. Among the most compact quadruples…
TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days

Lauren A. Sgro, Paul A. Dalba, Thomas M. Esposito +21
NASA's Transiting Exoplanet Survey Satellite (TESS) has identified over 7,000 candidate exoplanets via the transit method, with gas giants among the most readily detected due to th…
Seven new triply eclipsing triple star systems
S. A. Rappaport, T. Borkovits, T. Mitnyan +19
We have identified nearly a hundred close triply eclipsing hierarchical triple star systems from data taken with the space telescope TESS. These systems are noteworthy in that we c…
