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…
The Pan-Pacific Planet Search -- IX. A menagerie of companions orbiting evolved stars
Robert A. Wittenmyer, Alexander Venner, Tyler Fairnington +22
We present resolutions as to the nature of six speculative candidate companions proposed in the final data release of the Pan-Pacific Planet Search, a 6-year radial-velocity survey…
Mars as an Exoplanet: Lessons from a Planet at the Edge of Habitability
Stephen R. Kane, Paul K. Byrne, Skylar D'Angiolillo +5
Mars is the Solar System's canonical small, rocky planet that transitioned from early geologic activity and surface liquid water to a cold and arid planet with a thin, cold, CO…
Dynamical Stability and Habitability in the HD 20794 System
Stephen R. Kane
The Keplerian orbit of a terrestrial planet can be a significant driver in the evolution of surface conditions, as well as influencing the overall dynamics of the system. The HD 20…
Finding Alien Worlds in Queensland -- A Decade of MINERVA-Australis
Jonathan Horner, Robert A. Wittenmyer, Stephen R. Kane +2
Three decades ago, humanity entered the Exoplanet Era, with the discovery of the first planets orbiting other stars. Today, more than 6000 exoplanets are known - a tally recently b…
Smaller Than Earth Habitability Model (STEHM): The Lower Size Limit for Atmosphere Retention in the Habitable Zone
Michelle L. Hill, Stephen R. Kane, Bradford J. Foley +1
With recent advances in exoplanet observational techniques enabling the discovery of increasingly smaller planets, a crucial question emerges in the search for habitable planets: h…
