Scaling K2. VI. Reduced Small Planet Occurrence in High Galactic Amplitude Stars
Jon K. Zink, Kevin K. Hardegree-Ullman, Jessie L. Christiansen +13
In this study, we performed a homogeneous analysis of the planets around FGK dwarf stars observed by the Kepler and K2 missions, providing spectroscopic parameters for 310 K2 targe…
Mass Derivation of planets K2-21b and K2-21c from Transit Timing Variations
Maryame El Moutamid, Kevin B. Stevenson, Billy Quarles +5
While various indirect methods are used to detect exoplanets, one of the most effective and accurate methods is the transit method, which measures the brightness of a given star fo…
Revising Properties of Planet-Host Binary Systems. III. There is No Observed Radius Gap For Kepler Planets in Binary Star Systems
Kendall Sullivan, Adam L. Kraus, Daniel Huber +7
Binary stars are ubiquitous; the majority of solar-type stars exist in binaries. Exoplanet occurrence rate is suppressed in binaries, but some multiples do still host planets. Bina…
Report on Community Cadence Observing to Maximize the Scientific Output of the Keck Planet Finder
Erik Petigura, Andrew Howard, Jacob Bean +11
The arrival of the Keck Planet Finder (KPF) in 2022 represents a major advance in the precision radial velocity (PRV) capabilities of the W. M. Keck Observatory. In preparation for…
The TESS-Keck Survey. XIII. An Eccentric Hot Neptune with a Similar-Mass Outer Companion around TOI-1272
Mason G. MacDougall, Erik A. Petigura, Tara Fetherolf +58
We report the discovery of an eccentric hot Neptune and a non-transiting outer planet around TOI-1272. We identified the eccentricity of the inner planet, with an orbital period of…
Inferring the Rotation Period Distribution of Stars from their Projected Rotation Velocities and Radii: Application to late-F/early-G Kepler Stars
Kento Masuda, Erik A. Petigura, Oliver J. Hall
While stellar rotation periods may be measured from broadband photometry, the photometric modulation becomes harder to detect for slower rotators, which could bias…
