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…
TIC 366240660 - A Dynamically Active Triple With a Very Short Outer Period of 30.5 Days
S. A. Rappaport, T. Borkovits, G. Torres +17
Methods: We analyze TESS photometric data, radial velocity measurements, and eclipse timing variation curves for the triple star system, TIC 366240660, with a photodynamical code t…
TIC 433545934: The first 2+2 type doubly eclipsing binary with extra, mutual eclipses
Tamás Borkovits, Saul A. Rappaport, Petr Zasche +5
In this work we identify and photodynamically analyze TIC 433545934, the very first doubly eclipsing 2+2-type quadruple stellar system, which shows outer eclipses, too. One such ou…
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…
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…
EL CMi: confirmation of triaxial pulsation theory
G. Handler, S. A. Rappaport, D. Jones +10
Triaxial pulsators are a recently discovered group of oscillating stars in close binary systems that show pulsations around three axes at the same time. It has recently been theore…
X-Raying a Be star disk: fundamental parameters of the eclipsing binary Be star V658 Car
Tajan H. de Amorim, Alex C. Carciofi, Jonathan Labadie-Bartz +8
With its two stellar eclipses and two disk attenuations per binary orbit, V658 Carinae stands out as the first clear eclipsing Be + sdOB system. This rare alignment offers a unique…
The TESS Ten Thousand Catalog: 10,001 uniformly-vetted and -validated Eclipsing Binary Stars detected in Full-Frame Image data by machine learning and analyzed by citizen scientists
Veselin B. Kostov, Brian P. Powell, Aline U. Fornear +36
The Transiting Exoplanet Survey Satellite (TESS) has surveyed nearly the entire sky in Full-Frame Image mode with a time resolution of 200 seconds to 30 minutes and a temporal base…
Starspots on eclipsing giant stars I.: The sample and eclipse mapping examples
K. Oláh, B. Seli, A. Haris +12
Spotted stars in eclipsing binary systems allow us to gather significant information about the stellar surface inhomogeneities that is otherwise impossible from only photometric da…
The Discovery of Two Quadruple Star Systems with the Second and Third Shortest Outer Periods
Brian P. Powell, Guillermo Torres, Veselin B. Kostov +12
We present the discovery of two quadruple star systems -- TIC 285853156 and TIC 392229331 -- each consisting of two bound eclipsing binary stars. Among the most compact quadruples…
Tidally distorted stars are triaxial pulsators
Jim Fuller, Saul Rappaport, Rahul Jayaraman +2
Stars in close binaries are tidally distorted, and this has a strong effect on their pulsation modes. We compute the mode frequencies and geometries of tidally distorted stars usin…
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…
TIC 435850195: The Second Tri-Axial, Tidally Tilted Pulsator
Rahul Jayaraman, Saul Rappaport, Brian Powell +8
The Transiting Exoplanet Survey Satellite (TESS) has enabled the discovery of numerous tidally tilted pulsators (TTPs), which are pulsating stars in close binaries where the presen…
Characterization of the Scuti eclipsing binary KIC 4851217 and its tertiary companion as well as detection of tidally tilted pulsations
Z. Jennings, J. Southworth, S. A. Rappaport +3
Stellar theory enables us to understand the properties of stars at different stages of their evolution, and contributes to other fields of astrophysics such as galactic and exoplan…
