JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates

G. Cugno, M. Benisty, R. Teague +32

Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We pr…

GEMS JWST: Hold on to your HATS(-6 b), a sub-solar metallicity giant planet with water, methane and ammonia in its atmosphere

Giannina Guzmán Caloca, Caleb I. Cañas, Nicole L. Wallack +16

HATS-6 b is one of several recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) and is part of a JWST survey that aims to compare bulk and atmospheric properties of t…

Giant exoplanets are not fully mixed

Chantal Hemmann, Simon Müller, Ravit Helled

The interior structure and bulk composition of giant planets are not directly observable and must be inferred from models. Under the common assumption of a well-mixed, adiabatic en…

The evolution and internal structure of Neptunes and sub-Neptunes II. Convective mixing and thermal conductivity

Mark Eberlein, Ravit Helled

Sub-Neptunes and Neptunes are often modeled with distinct, fully convective layers. Yet, there are several arguments for compositions gradients that can inhibit convection. In thes…

Outstanding Questions in Giant Planet Theory

Ravit Helled

Giant planets have key role in shaping planetary systems. Their composition reveals information on the conditions at which planets form, and their interiors serve as natural labora…

Origin and characterization of super-Earths and sub-Neptunes

Léna Parc, Julia Venturini, François Bouchy +6

Super-Earths and sub-Neptunes represent the most common class of exoplanets discovered to date in our galaxy, yet they have no direct analogues in the Solar System. Since 2014, res…
