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…
Towards Instrument-Agnostic Exoplanet Candidate Prioritization
Vivaswan Kopparapu, Sibasish Laha, Brian P. Powell +3
We have developed a novel machine learning (ML) approach for predicting the likelihood of exoplanet candidate confirmation equally capable of performance on both TESS and Kepler da…
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…
NASA's Pandora SmallSat Mission: Simulating the Impact of Stellar Photospheric Heterogeneity and Its Correction
Benjamin V. Rackham, Aishwarya R. Iyer, Dániel Apai +28
Stellar photospheric heterogeneity is a dominant astrophysical systematic impacting exoplanet transmission spectroscopy. NASA's Pandora SmallSat Mission is designed to address this…
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.…
NASA's Pandora SmallSat Mission: Simulated Modeling and Retrieval of Near-Infrared Exoplanet Transmission Spectra
Yoav Rotman, Peter McGill, Luis Welbanks +22
Pandora is a SmallSat mission dedicated to understanding exoplanets and their host stars by disentangling the impact of stellar heterogeneity on exoplanet transmission spectra. Sel…
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…
A Catalog of M&M Eclipsing Binaries with TESS
Dominic Oddo, Diana Dragomir, Brian P. Powell +2
We present a catalog of 1292 low-mass (M&M) short-period eclipsing binaries observed by the TESS mission. Eclipsing binaries are useful for many aspects of stellar astrophysics, in…
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…
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…
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…
Absolute dimensions of solar-type eclipsing binaries. NY Hya: A test for magnetic stellar evolution models
T. C. Hinse, O. Baştürk, J. Southworth +29
The binary star NY Hya is a bright, detached, double-lined eclipsing system with an orbital period of just under five days with two components each nearly identical to the Sun and…
