Inhomogeneous Cloud Coverage and Altitude-Dependent Heat Transport on the Hot-Jupiter NGTS-10 Ab from its Optical-to-Infrared Phase Curve

Louis-Philippe Coulombe, Vivien Parmentier, Kevin B. Stevenson +15

Hot-Jupiters, gas giant planets with equilibrium temperatures above 1,000 K, host large temperature gradients between their permanent day- and nightsides, resulting in circulation…

An Evolving Cosmic Shoreline and Sandbar Bounding the Rocky Airless Valley

Barron K. Nguyen, Laura K. Schaefer, Xuan Ji +7

Recent JWST observations challenge the traditional 'cosmic shoreline' from both sides, revealing thick volatile atmospheres on the hottest close-in 'lava worlds,' where irradiation…

Hydrogen and Helium Dissolution, Outgassing, and Loss in Evolving Sub-Neptune Magma Oceans: Examining Demographic Features and Radius Evolution

Yao Tang, Jonathan J. Fortney, Laura K. Schaefer +1

Sub-Neptunes' molten interiors are expected to accommodate large quantities of volatiles, potentially altering their radius evolution. Previous studies have examined this effect in…

Horizontal transport as a source of disequilibrium chemistry on the nightside of a hot exoplanet

Vivien Parmentier, Kevin B. Stevenson, Luis Welbanks +15

Hot Jupiters have temperature gradients of several hundreds of degrees between their permanent day and nightsides. In equilibrium, the primary carbon reservoir is expected to trans…

Sub-Neptune Memories I: Implications of Inefficient Mantle Cooling and Silicate Rain

Roberto Tejada Arevalo, Akash Gupta, Adam Burrows +3

We explore the evolution of sub-Neptune (radii between 1.5 and 4 R) exoplanet interior structures using our upgraded evolution code, \texttt{APPLE}, which self-consi…
