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…

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…

The HD 60779 Planetary System: A Transiting Sub-Neptune on a 30-day Orbit and a More Massive Outer World

Victoria DiTomasso, David Charbonneau, Andrew Vanderburg +37

We present the discovery of the planetary system orbiting the bright (V = 7.2), nearby (35 pc), Sun-like star HD 60779, which has a mass of 1.050 +/- 0.044 solar masses and a radiu…

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…
