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…

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…

Atmospheric dynamics of IR-active particles released from Mars' surface

Mark I. Richardson, Samaneh Ansari, Bowen Fan +7

Surface release of radiatively active particles, with high infrared- (IR-)to-visible extinction ratios, has been proposed as a method of warming Mars. However, to warm Mars using a…

The Cosmic Shoreline Revisited: A Metric for Atmospheric Retention Informed by Hydrodynamic Escape

Xuan Ji, Richard D. Chatterjee, Brandon Park Coy +1

The "cosmic shoreline," a semi-empirical relation that separates airless worlds from worlds with atmospheres as proposed by K. J. Zahnle & D. C. Catling, is now guiding large-scale…

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…
