The K2 M67 Study: Precise Mass for a Turnoff Star in the Old Open Cluster M67
Eric L. Sandquist, David W. Latham, Robert. D. Mathieu +8
We present a study of the bright detached eclipsing main sequence binary WOCS 11028 (Sanders 617) in the open cluster M67. Although the binary has only one eclipse per orbital cycl…
Photometry of 10 Million Stars from the First Two Years of TESS Full Frame Images
Chelsea X. Huang, Andrew Vanderburg, András Pál +8
The Transiting Exoplanet Survey Satellite (TESS) is the first high-precision full-sky photometry survey in space. We present light curves from a magnitude limited set of stars and…
The Magellan-TESS Survey I: Survey Description and Mid-Survey Results
Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang +66
revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they…
A planet within the debris disk around the pre-main-sequence star AU Microscopii
Peter Plavchan, Thomas Barclay, Jonathan Gagné +84
AU Microscopii (AU Mic) is the second closest pre main sequence star, at a distance of 9.79 parsecs and with an age of 22 million years. AU Mic possesses a relatively rare and spat…
Eclipsing binaries in the open cluster Ruprecht 147. III: The triple system EPIC 219552514 at the main-sequence turnoff
Guillermo Torres, Andrew Vanderburg, Jason L. Curtis +3
Spectroscopic observations are reported for the 2.75 day, double-lined, detached eclipsing binary EPIC 219552514 located at the turnoff of the old nearby open cluster Ruprecht 147.…
Orbital Parameter Determination for Wide Stellar Binary Systems in the Age of Gaia
Logan A. Pearce, Adam L. Kraus, Trent J. Dupuy +4
The orbits of binary stars and planets, particularly eccentricities and inclinations, encode the angular momentum within these systems. Within stellar multiple systems, the magnitu…
Eclipsing binaries in the open cluster Ruprecht 147. II: EPIC 219568666
Guillermo Torres, Andrew Vanderburg, Jason L. Curtis +7
We report our spectroscopic monitoring of the detached, grazing, and slightly eccentric 12-day double-lined eclipsing binary EPIC 219568666 in the old nearby open cluster Ruprecht…
Radial Velocity Discovery of an Eccentric Jovian World Orbiting at 18 au
Sarah Blunt, Michael Endl, Lauren M. Weiss +25
Based on two decades of radial velocity (RV) observations using Keck/HIRES and McDonald/Tull, and more recent observations using the Automated Planet Finder, we found that the near…
K2-291 b: A rocky super-Earth in a 2.2 day orbit
Molly R. Kosiarek, Sarah Blunt, Mercedes Lopez-Morales +43
