Anisotropy in the Inner Core: Could It Be Due To Low-Order Convection?
نویسندگان
چکیده
A recently assembled data set of inner core-sensitive free oscillation splitting measurements and body wave differential travel times provides constraints on the patterns of anisotropy in the Earth's inner core. Applying a formalism that allows departures from radial symmetry and cylindrical anisotropy results in models with P-wave velocity distributions whose strength and pattern are incompatible with frozen-in anisotropy, but rather suggest a simple large-scale convection regime in the inner core.

Core/Shell structured nanoparticles for imaging and therapy
Introduction: Nanoparticles have several exciting applications in various fields of biomedicine. It has been found that among different classes of nanoparticles core/shell is most promising for field of nano-medical imaging and therapy due to their distinct advantages. The core/shell type nanoparticles can be generally comprising of two nanoparticles one act as a core (inner ma...
متن کاملEnergetics of Asteroid Dynamos and the Role of Compositional Convection
Introduction It has recently been argued that the observed paleomagnetism of angrite meteorites is most likely due to an early dynamo on the angrite parent body [1]. On Earth and other large silicate bodies, dynamo activity is thought to be sustained by a combination of thermal and compositional buoyancy [2]. Here I will argue that compositional buoyancy, if present, overwhelmingly dominates th...
متن کاملNumerical method for singularly perturbed fourth order ordinary differential equations of convection-diffusion type
In this paper, we have proposed a numerical method for singularly perturbed fourth order ordinary differential equations of convection-diffusion type. The numerical method combines boundary value technique, asymptotic expansion approximation, shooting method and finite difference method. In order to get a numerical solution for the derivative of the solution, the given interval is divided in...
متن کاملThermal and magnetic evolution of the Earth’s core
The magnetic field of the Earth is generated by convection in the liquid-core and the energy necessary for this process comes from the cooling of the core which provide several buoyancy sources. The thermodynamics of this system is used to relate the Ohmic dissipation in the core to all energy sources and to model the thermal evolution of the core. If the same dissipation is maintained just bef...
متن کاملEnergy Fluxes and Ohmic Dissipation in the Earth’s Core
Simulations have shown that convection-driven geodynamo models can produce reversing magnetic fields of a similar strength to those of the geomagnetic field. These simulations suggest that the ohmic dissipation arising from the geodynamo is not due solely to the largest scale harmonics of the magnetic field, but is dominated by contributions from smaller scale components. It is argued that, in ...
