Mass Constraints of the WASP-47 Planetary System from Radial Velocities
Evan Sinukoff, Andrew W. Howard, Erik A. Petigura +19
We report precise radial velocity (RV) measurements of WASP-47, a G star that hosts three transiting planets in close proximity (a hot Jupiter, a super-Earth and a Neptune-sized pl…
OGLE-2015-BLG-0196: Ground-based Gravitational Microlens Parallax Confirmed By Space-Based Observation
C. Han, A. Udalski, A. Gould +20
In this paper, we present the analysis of the binary gravitational microlensing event OGLE-2015-BLG-0196. The event lasted for almost a year and the light curve exhibited significa…
Spitzer Observations Confirm and Rescue the Habitable-Zone Super-Earth K2-18b for Future Characterization
Björn Benneke, Michael Werner, Erik Petigura +13
The recent detections of two transit events attributed to the super-Earth candidate K2-18b have provided the unprecedented prospect of spectroscopically studying a habitable-zone p…
K2 Discovers a Busy Bee: An Unusual Transiting Neptune Found in the Beehive Cluster
Christian Obermeier, Thomas Henning, Joshua E. Schlieder +21
Open clusters have been the focus of several exoplanet surveys but only a few planets have so far been discovered. The \emph{Kepler} spacecraft revealed an abundance of small plane…
197 Candidates and 104 Validated Planets in K2's First Five Fields
Ian J. M. Crossfield, David R. Ciardi, Erik A. Petigura +41
We present 197 planet candidates discovered using data from the first year of the NASA K2 mission (Campaigns 0-4), along with the results of an intensive program of photometric ana…
A Neptune-sized transiting planet closely orbiting a 5-10-million-year-old star
Trevor J. David, Lynne A. Hillenbrand, Erik A. Petigura +10
Theories of the formation and early evolution of planetary systems postulate that planets are born in circumstellar disks, and undergo radial migration during and after dissipation…
