The aim of this study is to determine through numerical simulations the extent and robustness three-dimensional torsional dynamics thermal convection in rotating spherical fluids at very low Prandtl numbers. It known that kinetic energy periodic axisymmetric flows propagates latitudinally on surface sphere. Here, it shown when axisymmetry broken a secondary Hopf bifurcation, flow starts drift a...

We develop a formalism that can be used to model slowly rotating superfluid Newtonian neutron stars. A simple two-fluid model is used to describe the matter, where one fluid consists of the superfluid neutrons that are believed to exist in the inner crust and core of mature neutron stars, while the other fluid is a charge neutral conglomerate of the remaining constituents (crust nuclei, core su...

Thermal convection is induced in a rotating differentially heated annulus by using central magnetic force field. The principle of the system used to simulate large scale such as that found planetary interiors or atmospheres but laboratory scaled model investigated geophysical flow fields. Results suggest fluids can be study phenomena microgravity environment. To quantify thermal forcing, rotati...

A double new class of solutions to the general relativity field equations describing interior spacetimes sourced by stationary cylindrical anisotropic fluids with principal stress directed along symmetry axis is displayed. These are required satisfy regularity and junction conditions so that they can be possibly used represent rotating astrophysical objects. Mathematical physical properties ana...
