Accelerating the Discovery of Steady‐States of Planetary Interior Dynamics With Machine Learning
Journal of Geophysical Research: Machine Learning and ComputationSimulating mantle convection often requires reaching a computationally expensive steady‐state, crucial for deriving scaling laws for thermal and dynamical flow properties and benchmarking numerical solutions.

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow
AGU AdvancesWith its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole

, 2001 The assumption that stationary hotspots underlie the Earth’s lithospheric plates has been most important in the development of the theory of plate tectonics. According to the fixed hotspot hypothesis seamount trails are formed by volcanism penetrating the

Sluggish thermochemical basal mantle structures support their long-lived stability
Nature CommunicationsLarge low shear-wave velocity provinces (LLSVPs) in the lowermost mantle are the largest geological structures on Earth, but their origin and age remain highly enigmatic.
