The K2-138 System: A Near-Resonant Chain of Five Sub-Neptune Planets Discovered by Citizen Scientists
Jessie L. Christiansen, Ian J. M. Crossfield, Geert Barentsen +25
K2-138 is a moderately bright (V = 12.2, K = 10.3) main sequence K-star observed in Campaign 12 of the NASA K2 mission. It hosts five small (1.6-3.3R_Earth) transiting planets in a…
Constraints on the Obliquities of Kepler Planet-Hosting Stars
Joshua N. Winn, Erik A. Petigura, Timothy D. Morton +8
Stars with hot Jupiters have obliquities ranging from 0-180 degrees, but relatively little is known about the obliquities of stars with smaller planets. Using data from the Califor…
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…
Validation of small Kepler transiting planet candidates in or near the habitable zone
Guillermo Torres, Stephen R. Kane, Jason F. Rowe +16
A main goal of NASA's Kepler Mission is to establish the frequency of potentially habitable Earth-size planets (eta Earth). Relatively few such candidates identified by the mission…
Light Curve Modulation of Low Mass Stars in K2. I. Identification of 508 Fast Rotators in the Solar Neighborhood
Dicy Ann Saylor, Sebastien Lépine, Ian Crossfield +1
The K2 mission is targeting large numbers of nearby (d<100 pc) GKM dwarfs selected from the SUPERBLINK proper motion survey (mu>40 mas yr^-1, V<20). Additionally, the mission is ta…
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…
