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…
