Mantle dynamics in super-Earths: Post-perovskite rheology and self-regulation of viscosity
The discovery of extra-solar “super-Earth” planets with sizes up to twice that of Earth has
prompted interest in their possible lithosphere and mantle dynamics and evolution. Simple …

Interior structure models of solid exoplanets using material laws in the infinite pressure limit
FW Wagner, F Sohl, H Hussmann, M Grott, H Rauer - Icarus, 2011 - Elsevier
The detection of low-mass extrasolar planets has initiated growing interest in massive rocky
bodies (super-Earths) for which no Solar System analogue does exist. Here, we present a …

Identification of post-pyrite phase transitions in SiO by a genetic algorithm
Using a first-principles genetic algorithm we predict an Fe 2 P phase is the first post-pyrite
phase of SiO 2 at low temperatures. This contrasts with a recently predicted cotunnite phase …
