The dark and featureless surface of rocky exoplanet LHS 3844 b from JWST mid-infrared spectroscopy
Sebastian Zieba, Laura Kreidberg, Brandon P. Coy +13
JWST has opened a new era in the study of rocky exoplanets, enabling direct characterization of their surfaces with mid-infrared spectroscopy. Different types of rock have distinct…
Impact of Subsurface Temperature Gradients on Emission Spectra of Airless Exoplanets: the Solid-state Greenhouse and Anti-Greenhouse
Xintong Lyu, Daniel D. B. Koll
An emerging goal of exoplanet science is to constrain the surface composition of airless exoplanets. Without the protection of an atmosphere, these planets are likely covered by a…
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…
Population-level Hypothesis Testing with Rocky Planet Emission Data: A Tentative Trend in the Brightness Temperatures of M-Earths
Brandon Park Coy, Jegug Ih, Edwin S. Kite +11
Determining which rocky exoplanets have atmospheres, and why, is a key goal for the James Webb Space Telescope. So far, emission observations of individual rocky exoplanets orbitin…
Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3
Michaël Gillon, Peter P. Pedersen, Benjamin V. Rackham +81
Located at the bottom of the main sequence, ultracool dwarf stars are widespread in the solar neighbourhood. Nevertheless, their extremely low luminosity has left their planetary p…
Super-Earth LHS3844b is tidally locked
Xintong Lyu, Daniel D. B. Koll, Nicolas B. Cowan +3
Short period exoplanets on circular orbits are thought to be tidally locked into synchronous rotation. If tidally locked, these planets must possess permanent day- and nightsides,…
Potential Atmospheric Compositions of TRAPPIST-1 c constrained by JWST/MIRI Observations at 15 m
Andrew P. Lincowski, Victoria S. Meadows, Sebastian Zieba +13
The first JWST observations of TRAPPIST-1 c showed a secondary eclipse depth of 421+/-94 ppm at 15 um, which is consistent with a bare rock surface or a thin, O2-dominated, low CO2…
No thick carbon dioxide atmosphere on the rocky exoplanet TRAPPIST-1 c
Sebastian Zieba, Laura Kreidberg, Elsa Ducrot +16
Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System (Gillon et al., 2017)…
