We present an updated transit ephemeris for the exoplanet WASP-18 b and critically examine the existence of a proposed second planet, WASP-18 c. Using 205 transit light curves from…
HWO Target Stars and Systems: Activity and Rotation Catalog (ARC) of Potential Target Stars for the Habitable Worlds Observatory
Tara Fetherolf, Arvind F. Gupta, Elisabeth R. Newton +7
A major goal of the Habitable Worlds Observatory (HWO) is to precisely characterize exoplanets and their atmospheres. However, magnetic activity from an exoplanet's host star can c…
Planetary Habitability Under the Light of a Rapidly Changing Star
Tara Fetherolf, Sadie G. Welter, Colby M. Ostberg +3
Planetary atmospheric energy budgets primarily depend on stellar incident flux. However, stellar variability can have major consequences for the evolution of planetary climates. In…
Resolving Individual Stars in Nearby Large Galaxies with the Habitable Worlds Observatory
Adam Smercina, Tara Fetherolf, Eric W. Koch +3
The varied and dynamic evolutionary histories of galaxies give rise to the stunning diversity in their properties that we observe in the present-day universe. HST, and now JWST, ha…
Interior and Climate Modeling of the Venus Zone Planet TOI-2285 b

As the discovery of exoplanets progresses at a rapid pace, the large number of known planets provides a pathway to assess the stellar and planetary properties that govern the clima…
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…
Probing Superheavy Dark Matter with Exoplanets
Mehrdad Phoroutan-Mehr, Tara Fetherolf
Exoplanets, with their large volumes and low temperatures, are ideal celestial detectors for probing dark matter (DM) interactions. DM particles can lose energy through scattering…
The TESS-Keck Survey XXIV: Outer Giants may be More Prevalent in the Presence of Inner Small Planets
Judah Van Zandt, Erik A. Petigura, Jack Lubin +38
We present the results of the Distant Giants Survey, a three-year radial velocity (RV) campaign to search for wide-separation giant planets orbiting Sun-like stars known to host an…
Modeling Spitzer 3.6 and 4.5 m Eclipse Depths for the Inflated Hot Jupiter in the Evolved Binary System HD 202772
Arthur D. Adams, Kimberly Bott, Paul A. Dalba +9
As an inflated Hot Jupiter orbiting an early-type primary star in the evolved binary HD 202772 system, HD 202772 A b's presence invites a study of how such a planet forms and evolv…
The TESS-Keck Survey XX: 15 New TESS Planets and a Uniform RV Analysis of all Survey Targets
