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…
Understanding the Origins of Super-Puff Planets: A New Mass-Loss Regime Coupled to Planetary Evolution
Yao Tang, Jonathan J. Fortney, Ruth Murray-Clay +1
Super-puffs are a class of low-mass, large-radius planets that have challenged planet formation and evolution models. Their high inferred H/He mass fractions, required to explain t…
Assessing Core-Powered Mass Loss in the Context of Early Boil-Off: Minimal Long-Lived Mass Loss for the Sub-Neptune Population
Yao Tang, Jonathan J. Fortney, Ruth Murray-Clay
We develop a python-based state-of-the-art sub-Neptune evolution model that incorporates both the post-formation boil-off at young ages 1 Myr and long-lived core-powered mas…
Reassessing Sub-Neptune Structure, Radii, and Thermal Evolution
Yao Tang, Jonathan J. Fortney, Francis Nimmo +3
We present a novel python-based 1D sub-Neptune evolution model that emphasizes the thermal evolution and potential solidification of the rock/iron core and the structure of the rad…
A High Internal Heat Flux and Large Core in a Warm Neptune Exoplanet
Luis Welbanks, Taylor J. Bell, Thomas G. Beatty +16
Interactions between exoplanetary atmospheres and internal properties have long been hypothesized to be drivers of the inflation mechanisms of gaseous planets and apparent atmosphe…
Hazy with a chance of star spots: constraining the atmosphere of the young planet, K2-33b
Pa Chia Thao, Andrew W. Mann, Peter Gao +10
Although all-sky surveys have led to the discovery of dozens of young planets, little is known about their atmospheres. Here, we present multi-wavelength transit data for the super…
