TIC 184743498: The First Tri-Axial Stellar Pulsator
Valencia Zhang, Saul Rappaport, Rahul Jayaraman +4
We have discovered a Scuti pulsator in a tight binary (P = 1.053 d) with nine pulsation modes whose frequencies are between 38 and 56 d. Each of these modes exhibits amp…
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…
TIC 219006972: A Compact, Coplanar Quadruple Star System Consisting of Two Eclipsing Binaries with an Outer Period of 168 days
Veselin B. Kostov, Tamas Borkovits, Saul A. Rappaport +12
We present the discovery of a new highly compact quadruple star system, TIC 219006972, consisting of two eclipsing binary stars with orbital periods of 8.3 days and 13.7 days, and…
