Spectral Energy Distribution Analysis for Habitable Worlds Observatory Target Stars
Stephen R. Kane, Kaspar von Braun, Tara Fetherolf +1
The Habitable Worlds Observatory (HWO) will directly image and characterize planets potentially similar to Earth orbiting nearby stars. Accurate stellar properties, particularly ef…
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…
HWO Target Stars and Systems: A Prioritized Community List of Potential Stellar Targets for the Habitable Worlds Observatory's ExoEarth Survey
Noah W. Tuchow, Caleb K. Harada, Eric E. Mamajek +9
The HWO Target Stars and Systems 2025 (TSS25) list is a community-developed catalog of potential stellar targets for the Habitable Worlds Observatory (HWO) in its survey to directl…
HWO Target Stars and Systems: A Survey of Archival UV and X-ray Data
Sarah Peacock, David J. Wilson, Tyler Richey-Yowell +14
We assess archival high-energy data for key stars on the Habitable Worlds Observatory (HWO) Target Stars and Systems 2025 list, as stellar radiation is critical to shaping and inte…
Utilizing Machine Learning to Predict Host Stars and the Key Elemental Abundances of Small Planets
AmÃlcar R. Torres-Quijano, Natalie R. Hinkel, Caleb H. Wheeler +3
Stars and their associated planets originate from the same cloud of gas and dust, making a star's elemental composition a valuable indicator for indirectly studying planetary compo…
Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581
Michelle Kunimoto, Zifan Lin, Sarah Millholland +43
We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…
