R fluids
A theory of collisionless fluids is developed in a unified picture, where nonrotating (Ω̃1 = Ω̃2 = Ω̃3 = 0) figures with anisotropic (σ11 = σ22 = σ33) random velocity component distributions and rotating (Ω̃1 6= Ω̃2 6= Ω̃3) figures with isotropic (σ11 6= σ22 6= σ33) random velocity component distributions, make adjoints configurations to the same system. R fluids are defined as ideal, self-gravitatin...
متن کاملThe r-modes of rotating fluids
An analysis of the toroidal modes of a rotating fluid, by means of the differential equations of motion is not readily tractable. A matrix representation of the equations in a suitable basis, however, simplifies the problem considerably and reveals many of its intricacies. Let Ω be the angular velocity of the star and (l, m) be the two integers that specify a spherical harmonic function. One re...
متن کاملBounds on 2m/r for static perfect fluids
For spherically symmetric relativistic perfect fluid models, the well-known Buchdahl inequality provides the bound 2M/R 6 8/9, where R denotes the surface radius and M the total mass of a solution. By assuming that the ratio p/ρ be bounded, where p is the pressure, ρ the density of solutions, we prove a sharper inequality of the same type, which depends on the actual bound imposed on p/ρ. As a ...
متن کاملMembrane fluids and Dirac membrane fluids
The relation between two different methods of membrane fluid description is clarified by construction of combined method. Dirac membrane field appears naturally in new approach. It provides a possibility to consider new aspects of electrodynamics-type theories with electric and magnetic sources. The membrane fluid models automatically prohibit simulatenos existence of electric and magnetic curr...
