Stellar storms in other worlds: implications for the stability of exoplanetary atmospheres

Stellar storms in other worlds: implications for the stability of exoplanetary atmospheres

Stellar storms modify the atmospheric evolution of planets. ‘Hot Jupiter’ planets being very close to their host star, are often affected by such storms. In this week’s peculiar planet, Gopal Hazra, a post-doctoral fellow at the School of Physics, Trinity College Dublin, discusses effect of stellar storms on those planets using his self-consistent hydrodynamic models of planetary ...[Read More]

The geophysicist’s toybox

The geophysicist’s toybox

Simplified models or toy models explain the complex Earth processes fairly well, even though they are far from reality. In this week’s Geodynamics 101, Adam Beall, Research Associate at Cardiff University, discusses some of his favourite geophysical toy models! I remember being excited to first hear about scientists doing Earth modelling and imagined impressive computer visualisations of tec ...[Read More]

Magnetic field generation and its reversal in dynamo models

Magnetic field generation and its reversal in dynamo models

Generation and reversal of the Earth’s magnetic field have remained one of the most controversial topics. In this week’s geodynamics 101, Debarshi Majumder, a PhD student from the Indian Institute of Science, gives a brief overview of the theory of geodynamo reversal and discusses some of the preliminary results obtained from numerical modelling. A planetary magnetic reversal is one of ...[Read More]

Whole solid-Earth numerical simulation: Towards an understanding of mantle-core interactive dynamics

Whole solid-Earth numerical simulation: Towards an understanding of mantle-core interactive dynamics

Due to huge difference between the time scale of the mantle convection and the outer core convection, they are modelled separately. In this week’s News and Views, Masaki Yoshida from the Volcanoes and Earth’s Interior Research Center, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Japan, put forward the recent development on the modeling of the whole solid-Earth. The E ...[Read More]
