Comoving stars in Gaia DR1: An abundance of very wide separation co-moving pairs
Semyeong Oh, Adrian M. Price-Whelan, David W. Hogg +2
The primary sample of the {\it Gaia} Data Release 1 is the Tycho-Gaia Astrometric Solution (TGAS): 2 million Tycho-2 sources with improved parallaxes and proper motions r…
Probability of Physical Association of 104 Blended Companions to \textit{Kepler} Objects of Interest Using Visible and Near-Infrared Adaptive Optics Photometry
Dani Atkinson, Christoph Baranec, Carl Ziegler +2
We determine probabilities of physical association for stars in blended Kepler Objects of Interest, and find that of companions within $\sim4\arcsec$ are…
The Robo-AO KOI Survey: laser adaptive optics imaging of every Kepler exoplanet candidate
Carl Ziegler, Nicholas M. Law, Christoph Baranec +4
The Robo-AO Kepler Planetary Candidate Survey is observing every Kepler planet candidate host star (KOI) with laser adaptive optics imaging to hunt for blended nearby stars which m…
The population of long-period transiting exoplanets
Daniel Foreman-Mackey, Timothy D. Morton, David W. Hogg +2
The Kepler Mission has discovered thousands of exoplanets and revolutionized our understanding of their population. This large, homogeneous catalog of discoveries has enabled rigor…
Five Planets Transiting a Ninth Magnitude Star
Andrew Vanderburg, Juliette C. Becker, Martti H. Kristiansen +15
The Kepler mission has revealed a great diversity of planetary systems and architectures, but most of the planets discovered by Kepler orbit faint stars. Using new data from the K2…
Friends of Hot Jupiters. IV. Stellar companions beyond 50 AU might facilitate giant planet formation, but most are unlikely to cause Kozai-Lidov migration
Henry Ngo, Heather A. Knutson, Sasha Hinkley +11
Stellar companions can influence the formation and evolution of planetary systems, but there are currently few observational constraints on the properties of planet-hosting binary…
