Planet Candidates from K2 Campaigns 5-8 and Follow-Up Optical Spectroscopy
Erik A. Petigura, Ian J. M. Crossfield, Howard Isaacson +10
We present 151 planet candidates orbiting 141 stars from K2 campaigns 5-8 (C5-C8), identified through a systematic search of K2 photometry. In addition, we identify 16 targets as l…
K2-114b and K2-115b: Two Transiting Warm Jupiters
Avi Shporer, George Zhou, Benjamin J. Fulton +22
We report the first results from a search for transiting warm Jupiter exoplanets - gas giant planets receiving stellar irradiation below about erg s cm, equiva…
Three's Company: An additional non-transiting super-Earth in the bright HD 3167 system, and masses for all three planets
Jessie L. Christiansen, Andrew Vanderburg, Jennifer Burt +55
HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a…
Seeing double with K2: Testing re-inflation with two remarkably similar planets around red giant branch stars
Samuel K. Grunblatt, Daniel Huber, Eric Gaidos +15
Despite more than 20 years since the discovery of the first gas giant planet with an anomalously large radius, the mechanism for planet inflation remains unknown. Here, we report t…
K2-66b and K2-106b: Two extremely hot sub-Neptune-size planets with high densities
Evan Sinukoff, Andrew W. Howard, Erik A. Petigura +20
We report precise mass and density measurements of two extremely hot sub-Neptune-size planets from the K2 mission using radial velocities, K2 photometry, and adaptive optics imagin…
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…
