Planet Hunters. VIII. Characterization of 41 Long-Period Exoplanet Candidates from Kepler Archival Data
Ji Wang, Debra A. Fischer, Thomas Barclay +30
The census of exoplanets is incomplete for orbital distances larger than 1 AU. Here, we present 41 long-period planet candidates in 38 systems identified by Planet Hunters based on…
Eleven Multi-planet Systems from K2 Campaigns 1 & 2 and the Masses of Two Hot Super-Earths
Evan Sinukoff, Andrew W. Howard, Erik A. Petigura +14
We present a catalog of 11 multi-planet systems from Campaigns 1 and 2 of the K2 mission. We report the sizes and orbits of 26 planets split between seven 2-planet systems and four…
HII 2407: A Low-Mass Eclipsing Binary Revealed by K2 Observations of the Pleiades
Trevor J. David, John Stauffer, Lynne A. Hillenbrand +16
The star HII 2407 is a member of the relatively young Pleiades star cluster and was previously discovered to be a single-lined spectroscopic binary. It is newly identified here wit…
Know the Star, Know the Planet. V. Characterization of the Stellar Companion to the Exoplanet Host HD 177830
Lewis C. Roberts, Rebecca Oppenheimer, Justin R. Crepp +21
HD 177830 is an evolved K0IV star with two known exoplanets. In addition to the planetary companions it has a late-type stellar companion discovered with adaptive optics imagery. W…
High-speed imaging and wavefront sensing with an infrared avalanche photodiode array
Christoph Baranec, Dani Atkinson, Reed Riddle +4
Infrared avalanche photodiode arrays represent a panacea for many branches of astronomy by enabling extremely low-noise, high-speed and even photon-counting measurements at near-in…
Planets Around Low-Mass Stars (PALMS). V. Age-Dating Low-Mass Companions to Members and Interlopers of Young Moving Groups
Brendan P. Bowler, Evgenya L. Shkolnik, Michael C. Liu +22
We present optical and near-infrared adaptive optics (AO) imaging and spectroscopy of 13 ultracool (>M6) companions to late-type stars (K7-M4.5), most of which have recently been i…
