A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2

Alexander Venner, Andrew Vanderburg, Chelsea X. Huang +7

The transit method is currently one of our best means for the detection of potentially habitable "Earth-like" exoplanets. In principle, given sufficiently high photometric precisio…

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…

NGTS-EB-8: A double-lined eclipsing M+M binary discovered by citizen scientists

Sean M. O'Brien, Megan E. Schwamb, Christopher A. Watson +54

We report the identification and characterization of a new binary system composed of two near-equal mass M-dwarfs. The binary NGTS-EB-8 was identified as a planet candidate in data…

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…

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…

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…
