Observational constraints on Mercury’s thermal evolution and magnetic field indicate that the top part of the fluid core is stably stratified. Here we compute how a stable layer affects the core flow in response to Mercury’s main 88 day longitudi

Magnetic field observations from the MGS, MAVEN, and InSight missions reveal that a dynamo was active in Mars’s early history. One unique feature of Mars’s magnetic crustal field is its hemispheric dichotomy, where magnetic fields in the southern

Abstract Characterization of Earth's magnetic field is key to understanding dynamics of the core. We assess whether Iridium Communications magnetometer data can be used for this purpose since. The 66 Iridium satellites are in 86° inclination, 780 km

Understanding fluid flows in planetary cores and subsurface oceans, as well as their signatures in available observational data (gravity, magnetism, rotation, etc.), is a tremendous interdisciplinary challenge. In particular, it requires understandin

The future viability of the geosciences is challenged, since as a community we continue to lack demographic diversity representative of the wider population. Fundamentally, dominant cultural, histo...

The observation of global acoustic waves (p modes) in the Sun has been key to unveiling its internal structure and dynamics. A different kind of wave, known as sectoral Rossby modes, have been observed and identified, which potentially opens the door

Characterization of Earth’s magnetic field is key to understanding the dynamics of core flows and the dynamo. Satellite measurements of the magnetic field normally use precise magnetometers on a fe...

While the geosciences is interdisciplinary in nature, as a field it is not demographically diverse. Causes for this deficiency and proposed solutions have been identified over several years, but di...
