The role of thermal buoyancy in stabilizing the axial dipole field in rotating two-component convective dynamos
Debarshi Majumder, Binod Sreenivasan
Two-component convection driven by both compositional and thermal buoyancy within the fluid core of a rapidly rotating planet produces a predominantly axial dipole field. In a dyna…
Polarity transitions induced by symmetry-breaking outer boundary heat flux in rapidly rotating dynamos
Debarshi Majumder, Binod Sreenivasan
This study investigates, analytically and numerically, the role of an equatorially anti-symmetric lateral variation in heat flux at the outer boundary in polarity transitions in ra…
Inner core heterogeneity induced by a large variation in lower mantle heat flux
Aditya Varma, Binod Sreenivasan
Seismic mapping of the top of the inner core indicates two distinct areas of high P-wave velocity, the stronger one located beneath Asia, and the other located beneath the Atlantic…
The role of magnetic waves in tangent cylinder convection
Debarshi Majumder, Binod Sreenivasan
The secular variation of the geomagnetic field suggests that there are anticyclonic polar vortices in the Earth's core. Under the influence of a magnetic field, the polar azimuthal…
Self-similarity of the dipole-multipole transition in rapidly rotating dynamos
Debarshi Majumder, Binod Sreenivasan, Gaurav Maurya
The dipole-multipole transition in rapidly rotating dynamos is investigated through the analysis of forced magnetohydrodynamic waves in an unstably stratified fluid. The focus of t…
The role of slow magnetostrophic waves in the formation of the axial dipole in planetary dynamos
Aditya Varma, Binod Sreenivasan
The preference for the axial dipole in planetary dynamos is investigated through the analysis of wave motions in spherical dynamo models. Our study focuses on the role of slow magn…
Confinement of rotating convection by a laterally varying magnetic field
Binod Sreenivasan, Venkatesh Gopinath
Spherical shell dynamo models based on rotating convection show that the flow within the tangent cylinder is dominated by an off-axis plume that extends from the inner core boundar…
Experimental study of the convection in a rotating tangent cylinder
Kélig Aujogue, Alban Pothérat, Binod Sreenivasan +1
This paper experimentally investigates the convection in a fast rotating Tangent Cylinder (TC), for Ekman numbers down to , in a configuration relevant to the…
Little Earth Experiment: an instrument to model planetary cores
Kelig Aujogue, Alban Potherat, Ian Bates +2
In this paper, we present a new experimental facility, Little Earth Experiment, designed to study the hydrodynamics of liquid planetary cores. The main novelty of this apparatus is…
Onset of plane layer magnetoconvection at low Ekman number
Kélig Aujogue, Alban Pothérat, Binod Sreenivasan
We study the onset of magnetoconvection between two infinite horizontal planes subject to a vertical magnetic field aligned with background rotation. In order to gain insight into…
