Uniform Metallicity Measurements of M Dwarf Planet Hosts Support Metallicity-Dependent Sub-Neptune Formation
Emma V. Turtelboom, Steven Giacalone, Rebecca Gore +6
M dwarfs are the most common sites of planet formation in the Milky Way. Planet occurrence and composition are closely linked with the availability of metals in protoplanetary disk…
SPORES-HWO. II. Companion Mass Limits and Updated Planet Properties for 120 Future Exoplanet Imaging Targets from 35 yr of Precise Doppler Monitoring
Caleb K. Harada, Courtney D. Dressing, Emma V. Turtelboom +17
A goal of the future Habitable Worlds Observatory (HWO) is to directly image and spectroscopically characterize true Earth-analogs. However, if a large fraction of HWO target stars…
The star HIP 41378 potentially misaligned with its cohort of long-period planets
S. Grouffal, A. Santerne, V. Bourrier +29
The obliquity between the stellar spin axis and the planetary orbit, detected via the Rossiter-McLaughlin (RM) effect, is a tracer of the formation history of planetary systems. Wh…
TOI-880 is an Aligned, Coplanar, Multi-planet System
Elina Y. Zhang, Huan-Yu Teng, Fei Dai +22
Although many cases of stellar spin-orbit misalignment are known, it is usually unclear whether a single planet's orbit was tilted or if the entire protoplanetary disk was misalign…
Detection of H2O and CO2 in the Atmosphere of the Hot Super-Neptune WASP-166b with JWST
Andrew W. Mayo, Charles D. Fortenbach, Dana R. Louie +4
We characterize the atmosphere of the hot super-Neptune WASP-166b ( d, R, M, K) o…
Searching for Additional Planets in TESS Multi-Planet Systems: Testing Empirical Models Based on Kepler Data
Emma V. Turtelboom, Jamie Dietrich, Courtney D. Dressing +1
Multi-planet system architectures are frequently used to constrain possible formation and evolutionary pathways of observed exoplanets. Therefore, understanding the predictive and…
