52 Eclipsing Quadruple Star Candidates Discovered in TESS Full Frame Images
Veselin B. Kostov, Brian P. Powell, Saul A. Rappaport +25
We present the discovery of 52 eclipsing quadruple star candidates detected in TESS Full Frame Image eleanor data by machine learning and citizen scientists. The uniformly-vetted a…
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…
TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days
Veselin B. Kostov, Saul A. Rappaport, Tamas Borkovits +13
We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, Pout, of only 24.5 days. This "eclipses" the previous record set by l…
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…
Eclipse timing study of new hierarchical triple star candidates in the Northern Continuous Viewing Zone of TESS
T. Mitnyan, T. Borkovits, D. R. Czavalinga +4
We compiled a list of more than 3500 eclipsing binaries located in and near the Northern Continuous Viewing Zone (NCVZ) of the TESS space telescope that have a sufficient amount of…
Observational Detection of Higher Order Secular Perturbations in Tight Hierarchical Triple Stars
Tamás Borkovits, Tibor Mitnyan
In this work, we search for observational evidence of higher-order secular perturbations in three eclipsing binaries. These are slightly eccentric binaries, and they form the inner…
101 Eclipsing Quadruple Star Candidates Discovered in TESS Full Frame Images
Veselin B. Kostov, Brian P. Powell, Saul A. Rappaport +17
We present our second catalog of quadruple star candidates, containing 101 systems discovered in TESS Full-Frame Image data. The targets were initially detected as eclipsing binary…
Four New Compact Triply Eclipsing Triples found with Gaia and TESS
Donát R. Czavalinga, Tamás Borkovits, Tibor Mitnyan +2
This paper presents a comprehensive analysis of four triply eclipsing triple star systems, namely TIC 88206187, TIC 14839347, TIC 298714297, and TIC 66893949. The four systems with…
BU Canis Minoris -- the Most Compact Known Flat Doubly Eclipsing Quadruple System
Theodor Pribulla, Tamás Borkovits, Rahul Jayaraman +25
We have found that the 2+2 quadruple star system BU CMi is currently the most compact quadruple system known, with an extremely short outer period of only 121 days. The previous re…
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…
Newly identified compact hierarchical triple system candidates using Gaia DR3
Donát R. Czavalinga, Tibor Mitnyan, Saul A. Rappaport +5
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…
