Constraining the lives and times of exoplanets through evolutionary Bayesian retrievals

Harrison Nicholls, Tim Lichtenberg, Ben Riegler +2

The paper introduces a Bayesian retrieval framework that models the time‑evolution of exoplanet interiors and atmospheres, allowing constraints on their formation histories and vol…

Sulfur photochemistry observationally traces mantle redox states of rocky planets

Ioannis Panagiotou, Tim Lichtenberg, Shang-Min Tsai +1

The study models how sulfur chemistry in rocky exoplanet atmospheres reflects the redox state of their mantles, showing that photochemical signatures of SO2 are detectable with JWS…

Atmospheric evolution through outgassing and escape on young molten rocky exoplanets

Emma Postolec, Tim Lichtenberg, Harrison Nicholls +2

The paper models how outgassing from a cooling magma ocean and atmospheric escape together shape the early atmospheres of rocky exoplanets, exploring how factors like stellar type,…

Reflation: redox-driven atmospheric inflation as tracer of super-Earth geochemistry

Lorenzo Cesario, Tim Lichtenberg, Mara Attia +3

The paper proposes that the redox state of a super‑Earth’s mantle can cause a temporary re‑inflation of its atmosphere by shifting outgassed volatiles from carbon‑rich to hydrogen‑…

Coupled atmospHere Interior modeL Intercomparison (CHILI). I. Evolutionary Modelling -- Primordial Magma Oceans of Earth and Venus

Harrison Nicholls, Joshua Krissansen-Totton, Tim Lichtenberg +22

Earth and Venus represent two evolutionary outcomes arising from initially molten 'magma ocean' periods, followed by lifetimes of chemical and geophysical divergence. Their physics…

Geophysical and atmospheric implications of O-dependent melting on rocky exoplanets

Mariana Sastre, Tim Lichtenberg, Laurent Soucasse +3

The geochemical evolution of long-lived magma oceans is strongly regulated by volatile exchange between the molten mantle and the atmosphere. For planets inside the runaway-greenho…
