Upper Limits on Stellar Companions to the Kepler-34 and Kepler-35 Systems
Carlos Jurado, Lauren M. Weiss, Laura Daclison +3
We obtained new spectra of Kepler-34 and Kepler-35 with Keck-HIRES, nearly a decade after these systems were originally characterized with this spectrograph and other instruments,…
97 Eclipsing Quadruple Star Candidates Discovered in TESS Full Frame Images
Veselin B. Kostov, Brian P. Powell, Saul A. Rappaport +17
We present a catalog of 97 uniformly-vetted candidates for quadruple star systems. The candidates were identified in TESS Full Frame Image data from Sectors 1 through 42 through a…
TESS Eclipsing Binary Stars. I. Short cadence observations of 4584 eclipsing binaries in Sectors 1-26
Andrej Prsa, Angela Kochoska, Kyle E. Conroy +44
In this paper we present a catalog of 4584 eclipsing binaries observed during the first two years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binar…
Photodynamical Modeling of the Fascinating Eclipses in the Triple-Star System KOI-126
Mitchell E. Yenawine, William F. Welsh, Jerome A. Orosz +7
We explore the fascinating eclipses and dynamics of the compact hierarchical triple star system KOI-126 (KIC 5897826). This system is comprised of a pair of M-dwarf stars (KOI-126…
TIC 454140642: A Compact, Coplanar, Quadruple-lined Quadruple Star System Consisting of Two Eclipsing Binaries
Veselin B. Kostov, Brian P. Powell, Guillermo Torres +30
We report the discovery of a compact, coplanar, quadruply-lined, eclipsing quadruple star system from TESS data, TIC 454140642, also known as TYC 0074-01254-1. The target was first…
Fast Transit Computation Using Tabulated Stellar Intensities
Donald R. Short, Jerome A. Orosz, Gur Windmiller +1
Limb darkening laws are convenient parameterizations of the stellar intensity center-to-limb variation, and their use is ubiquitous in eclipse and transit modeling. But they are no…
