Geomagnetic signatures of the slurry F-layer inferred from dynamo simulations
Ludovic Huguet, Thomas Frasson, Souvik Naskar +5
Seismic observations indicate that the lowermost portion of Earth's liquid core is density stratified. The existence of this so-called F-layer challenges classical theories of core…

Accessing the dipole-multipole transition in rapidly rotating spherical shell dynamos
Andrew T. Clarke, Christopher J. Davies, Souvik Naskar +1
Polarity reversals are a key feature of Earth's magnetic field, yet the processes governing them are still poorly understood. Dipole reversals have been found in many numerical dyn…

Force balances in spherical shell rotating convection
S. Naskar, C. J. Davies, J. E. Mound +1
Significant progress has been made in understanding planetary core dynamics using numerical models of rotating convection (RC) in spherical shell geometry. However, the behaviour o…
