JWST MIRI reveals a potential atmosphere on the ultra-hot rocky planet TOI-431b
Cole Smith, Brandon Park Coy, Megan Weiner Mansfield +13
An open question in exoplanet science is whether rocky exoplanets extremely close in to their host stars, `lava worlds', can retain significant atmospheres. Thermal emission observ…
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…
Evidence for an Atmosphere on the Ultra-Short Period super-Earth HD 3167 b
Brandon Park Coy, Qiao Xue, Megan Weiner Mansfield +14
'Lava worlds'-Earth-sized planets hot enough (Teq >~ 1100 K) to melt their dayside silicate surfaces-have emerged as promising candidates for atmospheric detection and characteriza…
A carbon-rich atmosphere on a windy pulsar planet
Michael Zhang, Maya Beleznay, Timothy D. Brandt +17
A handful of enigmatic Jupiter-mass objects have been discovered orbiting pulsars. One such object, PSR\,J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum…
The JWST Rocky Worlds DDT Program reveals GJ 3929b to likely be a bare rock
Qiao Xue, Michael Zhang, Brandon P. Coy +14
We report first results from the JWST Rocky Worlds Director's Discretionary Time program. Two secondary eclipses of the terrestrial exoplanet GJ 3929b were recently observed using…
The Role of Tectonic Luck in Long-Term Habitability of Abiotic Earth-like Planets
Brandon Park Coy, Edwin S. Kite, R. J. Graham
Carbonate-silicate weathering feedback is thought to stabilize Earth's climate on geologic timescales. If climate warms, faster mineral dissolution and increased rainfall speed up…
