Kepler Image-Subtracted Light Curves and Variable Star Catalog of NGC 6819
Melinda Soares-Furtado, Rianna Kuenzi, Rachel Lee McClure +11
Variable stars in open clusters are valuable probes of stellar evolution. They provide precise measurements of stellar properties, constrain cluster ages and distances, and trace t…
TIC 295741342: A Triply-Eclipsing Triple Star System with a Giant Tertiary
Brian P. Powell, Guillermo Torres, Veselin B. Kostov +4
We present the discovery and characterization of TIC 295741342, a triply-eclipsing triple star system with a giant tertiary. The eclipsing binary consists of two similar main-seque…
Discovery of the First Octupole Pulsation Mode in a delta Scuti Star: A Stationary l = 3 Sectoral Mode
S. A. Rappaport, R. Jayaraman, G. Handler +8
Aims. We are attempting to better understand how stellar pulsations in close binary systems are affected, and possibly induced, by tidal, Coriolis, and centrifugal forces. Methods.…
TOI-6692b: An eccentric 130 day period giant planet with a single transit from TESS
Allyson Bieryla, Karen A. Collins, George Zhou +46
We report the discovery and characterization of TOI-6692 b, an eccentric (e~0.54) Jupiter on a 130-day orbit. TOI-6692 b was first detected as a community TESS Object of Interest (…
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…
