We have identified more than a hundred close triply eclipsing hierarchical triple star systems from data taken with the space telescope TESS. Many of them have outer periods less t…
Search for the wide-orbit massive companion of XO-7b in the follow-up radial-velocity and transit-timing data: no significant clues
Z. Garai, T. Pribulla, R. Komžík
XO-7b is a hot Jupiter transiting a mag G0V-type star. The planetary system is interesting because the linear slope in the discovery radial-velocity (RV) data indicated…
TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906
Amy Tuson, Didier Queloz, Hugh P. Osborn +119
We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…
A Study of Nine Triply Eclipsing Triples
S. A. Rappaport, T. Borkovits, R. Gagliano +22
In this work we report the independent discovery and analysis of nine new compact triply eclipsing triple star systems found with the TESS mission: TICs 47151245, 81525800, 9901326…
TIC 114936199: A Quadruple Star System with a 12-day Outer Orbit Eclipse
Brian P. Powell, Saul A. Rappaport, Tamás Borkovits +19
We report the discovery with TESS of a remarkable quadruple star system with a 2+1+1 configuration. The two unique characteristics of this system are that (i) the inner eclipsing b…
Rapidly rotating stars and their transiting planets: KELT-17b, KELT-19Ab, and KELT-21b in the CHEOPS and TESS era
Zoltán Garai, Theodor Pribulla, József Kovács +4
Rapidly rotating early-type main-sequence stars with transiting planets are interesting in many aspects. Unfortunately, several astrophysical effects in such systems are not well u…
HD 183986: a high-contrast SB2 system with a pulsating component
Martin Vaňko, Theodor Pribulla, Pavol Gajdoš +7
There is a small group of peculiar early-type stars on the main sequence that show different rotation velocities from different spectral lines. This inconsistency might be due to t…
Six New Compact Triply Eclipsing Triples Found With TESS
S. A. Rappaport, T. Borkovits, R. Gagliano +21
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,…
Triply eclipsing triple stars in the northern TESS fields: TICs 193993801, 388459317 and 52041148
T. Borkovits, T. Mitnyan, S. A. Rappaport +23
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…
Exploiting timing capabilities of the CHEOPS mission with warm-Jupiter planets
Borsato L, Piotto G, Gandolfi D +75
We present 17 transit light curves of seven known warm-Jupiters observed with the CHaracterising ExOPlanet Satellite (CHEOPS). The light curves have been collected as part of the C…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Secular changes in the orbits of the quadruple system VW LMi
T. Pribulla, E. Puha, T. Borkovits +8
VW~LMi is the tightest known quadruple system with 2+2 hierarchy. It consists of a W UMa-type eclipsing binary (P12 = 0.47755 days) and another detached non-eclipsing binary (P34 =…
International observational campaign of the 2014 eclipse of EE Cep
D. Pieńkowski, C. Gałan, T. Tomov +64
Context. EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to ε Aur. The system is characterized by grey and asymmetric eclip…
Periodic transit timing variations and refined system parameters of the exoplanet XO-6b
Zoltán Garai, Theodor Pribulla, Richard Komžík +3
Only a few exoplanets are known to orbit around fast rotating stars. One of them is XO-6b, which orbits an F5V-type star. Shortly after the discovery, we started multicolor photome…
