Characterizing K2 Candidate Planetary Systems Orbiting Low-Mass Stars IV: Updated Properties for 86 Cool Dwarfs Observed During Campaigns 1-17
Courtney D. Dressing, Kevin Hardegree-Ullman, Joshua E. Schlieder +15
We present revised stellar properties for 172 K2 target stars that were identified as possible hosts of transiting planets during Campaigns 1-17. Using medium-resolution near-infra…
Kepler Planet Occurrence Rates for Mid-Type M Dwarfs as a Function of Spectral Type
Kevin K. Hardegree-Ullman, Michael C. Cushing, Philip S. Muirhead +1
Previous studies of planet occurrence rates largely relied on photometric stellar characterizations. In this paper, we present planet occurrence rates for mid-type M dwarfs using s…
Catalog of New K2 Exoplanet Candidates from Citizen Scientists
Jon K. Zink, Kevin K. Hardegree-Ullman, Jessie L. Christiansen +34
We provide 28 new planet candidates that have been vetted by citizen scientists and expert astronomers. This catalog contains 9 likely rocky candidates () and…
