Can radio occultations constrain Uranus or Neptune's internal rotation periods?
Christopher R. Mankovich, Alex B. Akins, Dustin Buccino +2
The shapes of fluid planets bear the signatures of rotational flattening and atmospheric flows. Precise knowledge of their shapes and wind profiles may therefore reveal their inter…
The Evolution and Internal Structure of Neptunes and Sub-Neptunes: The importance of thermal conductivity in non-convective regions
Mark Eberlein, Ravit Helled
Neptunes and sub-Neptunes are typically modeled under the assumption that the interior is adiabatic and consists of distinct layers. However, formation models indicate that composi…
GEMS JWST: Transmission spectroscopy of TOI-5205b reveals significant stellar contamination and a metal-poor atmosphere
Caleb I. Cañas, Jacob Lustig-Yaeger, Shang-Min Tsai +21
Recent discoveries of transiting giant exoplanets () around M dwarfs (GEMS) present an opportunity to investigate their atmospheric compositions and…
Densities of small planets around the M dwarfs TOI-4336 A and TOI-4342 with ESPRESSO: Three sub-Neptunes, one super-Earth, and a Neptune-mass candidate
Léna Parc, Charles Cadieux, Nolan Grieves +27
We present the characterization of two planetary systems orbiting the M dwarfs TOI-4336 A (M3.5V) and TOI-4342 (M0V), each hosting two transiting planets previously validated with…
How Internal Structure Shapes the Metallicity of Giant Exoplanets
Lorenzo Peerani, Saburo Howard, Ravit Helled
The composition and internal structure of gas giant exoplanets encode key information about their formation and evolution. We investigate how different assumed interior structures…
Towards an agnostic algorithm for sampling empirical structure models: The case of Uranus and Neptune
Stefano Wirth, Luca Morf, Ravit Helled
We present an algorithm to efficiently sample the full space of planetary interior density profiles. Our approach uses as few assumptions as possible to pursue an agnostic algorith…
