A General Class of Self-similar Self-gravitating Fluids
I present a general classification of self-similar solutions to the equations of gravitational hydrodynamics that contain many previous results as special cases. For cold flows with spherical symmetry, the solution space can be classified into several regions of behavior similar to the Bondi solutions for steady flow. A full description of these solution is possible, which serves as the asympto...
متن کاملA class of self-gravitating accretion disks
We consider a class of steady-state self-gravitating accretion disks for which efficient cooling mechanisms are assumed to operate so that the disk is self-regulated at a condition of approximate marginal Jeans stability. In an earlier paper, this scenario had been shown to lead naturally, in the absence of a central point mass, to a self-similar solution characterized by a flat rotation curve....
متن کاملAxisymmetric Self-similar Equilibria of Self-gravitating Isothermal Systems
All axisymmetric self-similar equilibria of self-gravitating, rotating, isothermal systems are identified by solving the nonlinear Poisson equation analytically. There are two families of equilibria: (1) Cylindrically symmetric solutions in which the density varies with cylindrical radius as R, with 0 ≤ α ≤ 2. (2) Axially symmetric solutions in which the density varies as f(θ)/r, where r is the...
متن کاملSelf-similar condensation of rotating magnetized self-gravitating isothermal filaments
Ordinary differential equations describing the self-similar collapse of a rotating, magnetized, selfgravitating and isothermal filament are derived. Explicit homologous solutions are studied with special emphasis on the bifurcation that occurs at the magnetosonic critical point. It is shown that there is a critical value for the toroidal magnetic field slope at the origin above which no bifurca...
متن کاملThe Weyl Tensor and Equilibrium Configurations of Self–gravitating Fluids
It is shown that (except for two well defined cases), the necessary and sufficient condition for any spherically symmetric distribution of fluid to leave the state of equilibrium (or quasi–equilibrium), is that the Weyl tensor changes with respect to its value in the state of equilibrium (or quasi–equilibrium). ∗Postal address: Apartado 80793, Caracas 1080A, Venezuela; E-mail address: laherrera...
