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…
