Most Rocky Sub-Neptunes are Molten: Mapping the Solidification Shoreline for Gas Dwarf Exoplanets

Robb Calder, Oliver Shorttle, Harrison Nicholls +2

Sub-Neptunes are the most common type of detected exoplanet, yet their observed masses and radii are degenerate with several interior structures. One possibility is that sub-Neptun…

Coupled atmospHere Interior modeL Intercomparison (CHILI) Protocol Version 1.0: A CUISINES Intercomparison Project of Magma Ocean Models

Tim Lichtenberg, Laura Schaefer, Joshua Krissansen-Totton +23

Spectroscopic characterization of rocky exoplanets with the James Webb Space Telescope has brought the origin and evolution of their atmospheres into the focus of exoplanet science…

Onset of habitable conditions on the Hadean Earth set by feedback between tides and greenhouse forcing

Marijn R. van Dijk, Harrison Nicholls, Tim Lichtenberg

In the aftermath of the Moon-forming giant impact, the Hadean Earth's mantle and surface crystallized from a global magma ocean blanketed by a dense volatile-rich atmosphere. While…

Volatile-rich evolution of molten super-Earth L 98-59 d

Harrison Nicholls, Tim Lichtenberg, Richard D. Chatterjee +3

Small low-density exoplanets are sculpted by strong stellar irradiation, but their primordial compositions and subsequent evolution are still unknown. Two often-considered scenario…

AGNI: A radiative-convective model for lava planet atmospheres

Harrison Nicholls, Raymond Pierrehumbert, Tim Lichtenberg

It is important that we are able to accurately model the atmospheres of (exo)planets. This is because atmospheres play a central role in setting a planet's thermochemical environme…

Absence of a Runaway Greenhouse Limit on Lava Planets

Iris D. Boer, Harrison Nicholls, Tim Lichtenberg

Climate transitions on exoplanets offer valuable insights into the atmospheric processes governing planetary habitability. Previous pure-steam atmospheric models show a thermal lim…

Self-limited tidal heating and prolonged magma oceans in the L 98-59 system

Harrison Nicholls, Claire Marie Guimond, Hamish C. F. C. Hay +3

Rocky exoplanets accessible to characterisation often lie on close-in orbits where tidal heating within their interiors is significant, with the L 98-59 planetary system being a pr…
