Increased Surface Temperatures of Habitable White Dwarf Worlds Relative to Main-Sequence Exoplanets
Aomawa L. Shields, Eric T. Wolf, Eric Agol +1
Discoveries of giant planet candidates orbiting white dwarf stars and the demonstrated capabilities of the James Webb Space Telescope bring the possibility of detecting rocky plane…
A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations
Kento Masuda, Jessica E. Libby-Roberts, John H. Livingston +49
Kepler-51 is a -old Sun-like star hosting three transiting planets with radii - and orbital periods -$130\,\mathrm{day…
Updated forecast for TRAPPIST-1 times of transit for all seven exoplanets incorporating JWST data
Eric Agol, Natalie H. Allen, Björn Benneke +12
The TRAPPIST-1 system has been extensively observed with JWST in the near-infrared with the goal of measuring atmospheric transit transmission spectra of these temperate, Earth-siz…
An Earth-Mass Planet and a Brown Dwarf in Orbit Around a White Dwarf
Keming Zhang, Weicheng Zang, Kareem El-Badry +8
Terrestrial planets born beyond 1-3 AU have been theorized to avoid being engulfed during the red-giant phases of their host stars. Nevertheless, only a few gas-giant planets have…
A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST
TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
The Implications of Thermal Hydrodynamic Atmospheric Escape on the TRAPPIST-1 Planets
Megan T. Gialluca, Rory Barnes, Victoria S. Meadows +3
JWST observations of the 7-planet TRAPPIST-1 system will provide an excellent opportunity to test outcomes of stellar-driven evolution of terrestrial planetary atmospheres, includi…
