Four Sub-Saturns with Dissimilar Densities: Windows into Planetary Cores and Envelopes
Erik A. Petigura, Evan Sinukoff, Eric Lopez +12
We present results from a Keck/HIRES radial velocity campaign to study four sub-Saturn-sized planets, K2-27b, K2-32b, K2-39b, and K2-108b, with the goal of understanding their mass…
C/O and O/H Ratios Suggest Some Hot Jupiters Originate Beyond the Snow Line
John M. Brewer, Debra A. Fischer, Nikku Madhusudhan
The elemental compositions of planet hosting stars serve as proxies for the primordial compositions of the protoplanetary disks within which the planets form. The temperature profi…
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…
An ancient extrasolar system with five sub-Earth-size planets
T. L. Campante, T. Barclay, J. J. Swift +38
The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-r…
Stellar Parameters for HD 69830, a Nearby Star with Three Neptune Mass Planets and an Asteroid Belt
Angelle Tanner, Tabetha S. Boyajian, Kaspar von Braun +9
We used the CHARA Array to directly measure the angular diameter of HD 69830, home to three Neptune mass planets and an asteroid belt. Our measurement of 0.674+/-0.014 milli-arcsec…
Newly-Discovered Planets Orbiting HD~5319, HD~11506, HD~75784 and HD~10442 from the N2K Consortium
Matthew J. Giguere, Debra A. Fischer, Matthew J. Payne +4
Initially designed to discover short-period planets, the N2K campaign has since evolved to discover new worlds at large separations from their host stars. Detecting such worlds wil…
