Mantle Convection and Nightside Volcanism on Lava World K2-141 b
Tobias G. Meier, Claire Marie Guimond, Raymond T. Pierrehumbert +13
Ultra-short period lava worlds offer a unique window into the coupled evolution of planetary interior and atmospheres under extreme irradiation. In this study, we investigate the m…
Mantle Differentiation, Mixing and Interior-Exterior Exchange
Takashi Nakagawa, Charitra Jain, Diogo L. Lourenco +2
We review the formation of large-scale heterogeneity in the solid Earth from the magma ocean phase to the present day, focusing on lower-mantle structure and evolution, as well as…
Geodynamics of super-Earth GJ 486b
Tobias G. Meier, Dan J. Bower, Tim Lichtenberg +8
Many super-Earths are on very short orbits around their host star and, therefore, more likely to be tidally locked. Because this locking can lead to a strong contrast between the d…
Interior dynamics of super-Earth 55 Cancri e
Tobias G. Meier, Dan J. Bower, Tim Lichtenberg +2
The ultra-short-period super-Earth 55 Cancri e has a measured radius of 1.8 Earth radii. Previous thermal phase curve observations suggest a strong temperature contrast between the…
The Tectonics and Volcanism of Venus: New Modes Facilitated by Realistic Crustal Rheology and Intrusive Magmatism
Jiacheng Tian, Paul J. Tackley, Diogo L. Lourenço
To explain Venus' young surface age and lack of plate tectonics, Venus' tectonic regime has often been proposed to be either an episodic-lid regime with global lithospheric overtur…
Plausible constraints on the range of bulk terrestrial exoplanet compositions in the Solar neighbourhood
Rob J. Spaargaren, Haiyang S. Wang, Stephen J Mojzsis +2
Rocky planet compositions regulate planetary evolution by affecting core sizes, mantle properties, and melting behaviours. Yet, quantitative treatments of this aspect of exoplanet…
Investigating the Feasibility of an Impact-Induced Martian Dichotomy
Harry A. Ballantyne, Martin Jutzi, Gregor J. Golabek +4
A giant impact is commonly thought to explain the dramatic contrast in elevation and crustal thickness between the two hemispheres of Mars known as the "Martian Dichotomy". Initial…
Hemispheric Tectonics on super-Earth LHS 3844b
Tobias G. Meier, Dan J. Bower, Tim Lichtenberg +2
The tectonic regime of rocky planets fundamentally influences their long-term evolution and cycling of volatiles between interior and atmosphere. Earth is the only known planet wit…
Dry Late Accretion inferred from Venus' coupled atmosphere and internal evolution
C. Gillmann, G. J. Golabek, S. N. Raymond +4
The composition of meteoritic material delivered to the terrestrial planets after the end of core formation as late accretion remains contentious. Because the evolution of Venus' a…
The influence of bulk composition on long-term interior-atmosphere evolution of terrestrial exoplanets
Rob J. Spaargaren, Maxim D. Ballmer, Dan J. Bower +2
Aims: The secondary atmospheres of terrestrial planets form and evolve as a consequence of interaction with the interior over geological time. We aim to quantify the influence of p…
Geoscience for understanding habitability in the solar system and beyond
Veronique Dehant, Vinciane Debaille, Vera Dobos +15
This paper reviews habitability conditions for a terrestrial planet from the point of view of geosciences. It addresses how interactions between the interior of a planet or a moon…
Can we constrain interior structure of rocky exoplanets from mass and radius measurements?
Caroline Dorn, Amir Khan, Kevin Heng +4
We present an inversion method based on Bayesian analysis to constrain the interior structure of terrestrial exoplanets, in the form of chemical composition of the mantle and core…
Mantle Dynamics in Super-Earths: Post-Perovskite Rheology and Self-Regulation of Viscosity
Paul J. Tackley, Michael Ammann, John P. Brodholt +2
Simple scalings suggest that super-Earths are more likely than an equivalent Earth-sized planet to be undergoing plate tectonics. Generally, viscosity and thermal conductivity incr…
