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…
Mass and Eccentricity Constraints in the WASP-47 Planetary System from a Simultaneous Analysis of Radial Velocities & Transit Timing Variations
Lauren M. Weiss, Katherine Deck, Evan Sinukoff +9
Measuring precise planet masses, densities, and orbital dynamics in individual planetary systems is an important pathway toward understanding planet formation. The WASP-47 system h…
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…
Three Temperate Neptunes Orbiting Nearby Stars
Benjamin J. Fulton, Andrew W. Howard, Lauren M. Weiss +17
We present the discovery of three modestly-irradiated, roughly Neptune-mass planets orbiting three nearby Solar-type stars. HD 42618 b has a minimum mass of M$_{\opl…
Revised Masses and Densities of the Planets around Kepler-10
Lauren M. Weiss, Leslie A. Rogers, Howard T. Isaacson +8
Determining which small exoplanets have stony-iron compositions is necessary for quantifying the occurrence of such planets and for understanding the physics of planet formation. K…
