The dynamics of planetary atmospheres

open access: yes, 2016
Current knowledge of the dynamics of the atmospheres of the planets is reviewed. This has expanded a great deal in recent years, due to the numerous space missions which have gathered new observational data. Nevertheless, there is also much which remains unknown, and many cases where new observations have simply posed additional questions of a ...

Solid–liquid phase change in planetary cores

open access: yesComptes Rendus. Physique
The ubiquitous phenomena of crystallization and melting occur in various geophysical contexts across many spatial and temporal scales. In particular, they take place in the iron core of terrestrial planets and moons, profoundly influencing their dynamics

Oxygen isotope shifts reveal fluid-fluxed melting in continental anatexis

open access: yesCommunications Earth & Environment
Fluid-flux melting is increasingly recognised as a key mechanism for continental crust growth and recycling, but the abundance and sources of the external fluids involved in this process are typically uncertain.

Dynamical circulation regimes in planetary (and exo-planetary) atmospheres

open access: yes, 2017
In this thesis, we study the effect of diurnally- and seasonally-varying forcing on the global circulation of planetary atmospheres explored within a large parameter space. This work focusses on studying the spacial and spectral energy budgets across a large range of planetary parameters as well as the momentum transfer as a response to diurnal and ...

Simulation and Experimental Study on Dynamic Characteristic of Planetary Gear Transmission

open access: yesJixie chuandong, 2019
In order to solve the problem of high failure rate in the operation of planetary power shift gearbox for engineering vehicles, a dynamics simulation model of planetary gearbox is established based on the dynamics transmission theory, and the rotational ...

Ringed versus Ringless Worlds: How Poynting–Robertson Drag Shapes Rings across the Solar System

open access: yesThe Astrophysical Journal Letters
Planetary rings are not only ubiquitous around the giant planets in the outer solar system, but have also been discovered around several small distant bodies. In contrast, no rings have been observed around any inner solar system objects.
