Eight new, triply eclipsing triple star systems
T. Borkovits, S. A. Rappaport, G. Torres +19
We have identified numerous triply eclipsing hierarchical triple star systems from observations made with the space telescope TESS. For many of these systems we can potentially det…
Ten new, ultracompact triply eclipsing triple star systems
T. Borkovits, S. A. Rappaport, T. Mitnyan +15
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…
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…
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…
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…
Diagnosing the Clumpy Protoplanetary Disk of the UXor Type Young Star GM Cephei
P. C. Huang, W. P. Chen, M. Mugrauer +29
UX Orionis stars (UXors) are Herbig Ae/Be or T Tauri stars exhibiting sporadic occultation of stellar light by circumstellar dust. GM\,Cephei is such a UXor in the young (~M…
Ori and Lib: Two new massive heartbeat binaries
Andrzej Pigulski, Monika K. Kaminska, Krzysztof Kaminski +28
We report the discovery of two massive eccentric systems with BRITE data, Ori and Lib, showing heartbeat effects close to the periastron passage. Lib exhibits shallow e…
On the nature of the candidate T-Tauri star V501 Aurigae
M. Vaňko, G. Torres, L. Hambálek +18
We report new multi-colour photometry and high-resolution spectroscopic observations of the long-period variable V501 Aur, previously considered to be a weak-lined T-Tauri star bel…
Long-Term Photometry of IC 348 with the YETI Network
D. J. Fritzewski, M. Kitze, M. Mugrauer +29
We present long-term photometric observations of the young open cluster IC 348 with a baseline time-scale of 2.4 yr. Our study was conducted with several telescopes from the Young…
