The First Evidence of a Host Star Metallicity Cut-off In The Formation of Super-Earth Planets
Kiersten M. Boley, Jessie L. Christiansen, Jon Zink +7
Planet formation is expected to be severely limited in disks of low metallicity, owing to both the small solid mass reservoir and the low opacity accelerating the disk gas dissipat…
No Evidence for More Earth-sized Planets in the Habitable Zone of Kepler's M versus FGK Stars
Galen J. Bergsten, Ilaria Pascucci, Kevin K. Hardegree-Ullman +3
Reliable detections of Earth-sized planets in the habitable zone remain elusive in the Kepler sample, even for M dwarfs. The Kepler sample was once thought to contain a considerabl…
Using Photometrically-Derived Properties of Young Stars to Refine TESS's Transiting Young Planet Survey Completeness
Rachel B. Fernandes, Kevin K. Hardegree-Ullman, Ilaria Pascucci +7
The demographics of young exoplanets can shed light onto their formation and evolution processes. Exoplanet properties are derived from the properties of their host stars. As such,…
Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops
Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …
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…
Enabling Exoplanet Demographics Studies with Standardized Exoplanet Survey Meta-Data
Prepared by the ExoPAG Science Interest Group, 2 on Exoplanet Demographics, Jessie L. Christiansen +18
Goal 1 of the National Academies of Science, Engineering and Mathematics Exoplanet Science Strategy is "to understand the formation and evolution of planetary systems as products o…
