New evidence for wet accretion of inner solar system planetesimals from meteorites Chelyabinsk andBenenitra
Ziliang Jin, Maitrayee Bose, Tim Lichtenberg +1
We investigated the hydrogen isotopic compositions and water contents of pyroxenes in two recent ordinary chondrite falls, namely, Chelyabinsk (2013 fall) and Benenitra (2018 fall)…
Inferring Shallow Surfaces on sub-Neptune Exoplanets with JWST
Shang-Min Tsai, Hamish Innes, Tim Lichtenberg +4
Planets smaller than Neptune and larger than Earth make up the majority of the discovered exoplanets. Those with H-rich atmospheres are prime targets for atmospheric characteri…
Hidden water in magma ocean exoplanets
Caroline Dorn, Tim Lichtenberg
We demonstrate that the deep volatile storage capacity of magma oceans has significant implications for the bulk composition, interior and climate state inferred from exoplanet mas…
A multispecies pseudoadiabat for simulating condensable-rich exoplanet atmospheres
R. J. Graham, Tim Lichtenberg, Ryan Boukrouche +1
Central stages in the evolution of rocky, potentially habitable planets may play out under atmospheric conditions with a large inventory of non-dilute condensable components. Varia…
Beyond runaway: initiation of the post-runaway greenhouse state on rocky exoplanets
Ryan Boukrouche, Tim Lichtenberg, Raymond T. Pierrehumbert
The runaway greenhouse represents the ultimate climate catastrophe for rocky, Earth-like worlds: when the incoming stellar flux cannot be balanced by radiation to space, the oceans…
Redox hysteresis of super-Earth exoplanets from magma ocean circulation
Tim Lichtenberg
Internal redox reactions may irreversibly alter the mantle composition and volatile inventory of terrestrial and super-Earth exoplanets and affect the prospects for atmospheric obs…
