Systematic Uncertainties in Rocky Exoplanet Reflected Light from Incomplete Laboratory BRDF Measurements
Leonardos Gkouvelis, Michael K. Shepard, Paul Helfenstein +2
The first observations of short-period rocky exoplanets have initiated the era of terrestrial exoplanet characterization. The interpretation of these observations relies on forward…
Improved Constraints on the Surface of LHS 3844 b from its Mid-Infrared Spectrum
Kimberly Paragas, Heather A. Knutson, Renyu Hu +4
The thermal emission spectra of terrestrial exoplanets provide a window into their surface compositions and corresponding geological processes. Close-in, rocky planets orbiting M d…
Masses of Potentially Habitable Planets Characterized by the Habitable Worlds Observatory
Kaz Gary, B. Scott Gaudi, Eduardo Bendek +5
Constraints on the masses of exoplanets directly imaged and characterized by the Habitable Worlds Observatory (HWO) are crucial for categorizing these planets and interpreting thei…
Validation of a Third Earth-sized Planet in the TOI-2267 Binary System
Michael Greklek-McKeon, Jonathan Gomez Barrientos, Heather A. Knutson +13
We report the validation of a third terrestrial exoplanet in the nearby (22 pc) TOI-2267 system. TOI-2267 is a binary system with stellar components TOI-2267A (M5, 3030 K) and TOI-…
Methane on the temperate exo-Saturn TOI-199b
Aaron Bello-Arufe, Renyu Hu, Mantas Zilinskas +10
Temperate ( K) gas giants represent an unexplored frontier in exoplanet atmospheric spectroscopy. Orbiting a G-type star every days, the Saturn-mass exopl…
First JWST thermal phase curves of temperate terrestrial exoplanets reveal no thick atmosphere around TRAPPIST-1 b and c
Michaël Gillon, Elsa Ducrot, Taylor J. Bell +30
We report JWST/MIRI 15 m phase curves of TRAPPIST-1 b and c, revealing thermal emission consistent with their irradiation levels, assuming no efficient heat redistribution. We f…
Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. I. Observations, Orbital and Physical Properties, and Exozodi Upper Limits
Charles Beichman, Aniket Sanghi, Dimitri Mawet +27
We report on coronagraphic observations of the nearest solar-type star, Cen A, using the MIRI instrument on the James Webb Space Telescope. With three epochs of observation (Au…
