Scaling K2 VII: Evidence for a high occurrence rate of hot sub-Neptunes at intermediate ages
Jessie L. Christiansen, Jon K. Zink, Kevin K. Hardegree-Ullman +6
The NASA K2 mission obtained high precision time-series photometry for four young clusters, including the near-twin 600-800 Myr-old Praesepe and Hyades clusters. Hot sub-Neptunes a…
Hot Jupiters Have Giant Companions: Evidence for Coplanar High-Eccentricity Migration
Jon Zink, Andrew Howard
This study considers the characteristics of planetary systems with giant planets based on a population-level analysis of the California Legacy Survey planet catalog. We identified…
Overfitting Affects the Reliability of Radial Velocity Mass Estimates of the V1298 Tau Planets
Sarah Blunt, Adolfo Carvalho, Trevor J. David +23
Mass, radius, and age measurements of young (<100 Myr) planets have the power to shape our understanding of planet formation. However, young stars tend to be extremely variable in…
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…
The mass determination of TOI-519 b: a close-in giant planet transiting a metal-rich mid-M dwarf
Taiki Kagetani, Norio Narita, Tadahiro Kimura +33
We report the mass determination of TOI-519 b, a transiting substellar object around a mid-M dwarf. We carried out radial velocity measurements using Subaru / InfraRed Doppler (IRD…
