TL;DR: In this paper, a growth model and Monte Carlo simulations are used to demonstrate that many intermediate-size exoplanets are water worlds, which matches the second peak of the exoplanet radius bimodal distribution.
Journal ArticleDOI
Structure and dynamics of cold water super-earths: the case of occluded ch4 and its outgassing
TL;DR: In this paper, the authors investigated the influence of methane on the thermodynamics and mechanics of the water mantle and found that including methane in the water matrix introduces a new phase (filled ice), resulting in hotter planetary interiors.
Journal ArticleDOI
The ice cap zone: a unique habitable zone for ocean worlds
Ramses M. Ramirez,Amit Levi +1 more
TL;DR: In this article, the authors model the Levi et al. mechanism and use latitudinally-dependent non-grey energy balance and single-column radiative-convective climate models and find that this mechanism may be sustained on ocean worlds that rotate at least 3 times faster than the Earth.
Journal ArticleDOI
Volatile transport inside super-earths by entrapment in the water-ice matrix
TL;DR: In this article, the authors adopt the theory developed by van der Waals & Platteeuw for modeling solid solutions, often used for modeling clathrate hydrates, and modify it in order to estimate the thermodynamic stability field of a new phase called methane filled ice Ih.
Journal ArticleDOI
The Abundance of Atmospheric CO2 in Ocean Exoplanets: a Novel CO2 Deposition Mechanism
TL;DR: In this paper, the abundance of CO2 in the atmosphere has two possible states: wind-driven circulation is the dominant CO2 exchange mechanism, where the exact value depends on the subtropical ocean surface temperature and the deep ocean temperature.
