A Century of Radial Velocity and Astrometric Monitoring of 70 Oph AB: New PFS Data and Constraints on Planetary Companions
Yiting Li, Michael R. Meyer, Skylar D'Angiolillo +29
At a distance of 5.1 pc, the 70 Oph AB binary star system is one of the most favorable targets for future direct imaging and astrometry missions surveying mature, terrestrial plane…
Imaging Venus-like Worlds: Spectral, Polarimetric, and UV Diagnostics for the Habitable Worlds Observatory
Stephen R. Kane, Kimberly M. Bott, Kenneth E. Goodis Gordon +15
Understanding planetary habitability requires a comparative approach that explores the divergent evolutionary outcomes of Earth and Venus. The Habitable Worlds Observatory (HWO) wi…
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…
Requirements for Joint Orbital Characterization of Cold Giants and Habitable Worlds with Habitable Worlds Observatory
Sabina Sagynbayeva, Asif Abbas, Stephen R. Kane +10
We determine optimal requirements for the joint detection of habitable-zone planets and cold giant planets with the Habitable Worlds Observatory (HWO). Analysis of 164 nearby stars…
A Statistical Method for Constraining the Capability of the Habitable Worlds Observatory to Understand Ozone Onset Time in Earth Analogs
Sarah Blunt, Eric L. Nielsen, Elisabeth R. Newton +8
The oxygenation of Earth's atmosphere 2.3 billion years ago, which on exoplanets is expected to be most detectable via the UV ozone feature at 0.25 m, is often regarded a…
