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…
Radial Velocity Strategies for the Orbital Refinement of Exoplanet Direct Imaging Targets
Zhexing Li, Stephen R. Kane, Sarah Blunt +1
Many potential direct imaging candidates suffer from large orbital period uncertainties, leading to challenges in accurate predictions of future orbital positions and imprecise dir…
No Giant Planets in the Eta Cassiopeiae System: Dynamical Implications of a Wide Binary Companion
Stephen R. Kane, Zhexing Li, Michelle L. Hill +3
Given the vast number of stars that exist within binary systems, it remains important to explore the effect of binary star environments on the formation and evolution of exoplaneta…
Optimising Radial Velocity Detection Limits for Southern Habitable Worlds Observatory Targets
Robert A. Wittenmyer, Adriana Errico, Timothy R. Holt +5
The planned NASA Habitable Worlds Observatory (HWO) flagship mission aims to image and spectroscopically characterise 25 Earth-size planets in the habitable zones of their stars. H…
The Roman coronagraph community participation program: observation planning
Schuyler G. Wolff, Jason Wang, Karl Stapelfeldt +18
The Coronagraphic Instrument onboard the Nancy Grace Roman Space Telescope is an important stepping stone towards the characterization of habitable, rocky exoplanets. In a technolo…
