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…
