New input data for synthetic AGB evolution [PDF]

open access: yes, 1998
Analytic formulae are presented to construct detailed secular lightcurves of both early asymptotic giant branch (AGB) and thermally pulsing AGB stars.

Mantle convection and the state of the Earth's interior [PDF]

open access: yes
During 1983 to 1986 emphasis in the study of mantle convection shifted away from fluid mechanical analysis of simple systems with uniform material properties and simple geometries, toward analysis of the effects of more complicated, presumably more ...

Accelerating the Discovery of Steady‐States of Planetary Interior Dynamics With Machine Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation
Simulating 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.

Volcanism by melt-driven Rayleigh-Taylor instabilities and possible consequences of melting for admittance ratios on Venus [PDF]

open access: yes
A large number of volcanic features exist on Venus, ranging from tens of thousands of small domes to large shields and coronae. It is difficult to reconcile all these with an explanation involving deep mantle plumes, since a number of separate arguments ...

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow

open access: yesAGU Advances
With 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

Two-dimensional numerical experiments on mantle convection with stress-history-dependent rheology: toward self-consistent reproduction of plate tectonics

open access: yesEarth, Planets and Space
We developed a numerical model of thermal convection of highly viscous incompressible fluids, aiming at reproducing plate tectonics in the framework of mantle convection.
