We consider the problem of the gravitational collapse of isothermal spheres by applying the similarity method to the gas-dynamic flow. We argue that a previous solution obtained by Larson and Penston to describe the stages prior to core formation is physically artificial; however, we find that the flow following core formation does exhibit self-similar properties.The latter similarity solution shows that the inflow in the dense central regions proceeds virtually at free-fall before the material… 
SPHERICALLY SYMMETRIC, COLD COLLAPSE: THE EXACT SOLUTIONS AND A COMPARISON WITH SELF-SIMILAR SOLUTIONS
We present the exact solutions for the collapse of a spherically symmetric cold (i.e., pressureless) cloud under its own self-gravity, valid for arbitrary initial density profiles and not restricted
Self-Similar Collapse of an Isopedic Isothermal Disk
We study the gravitational collapse of an isothermal disk which is isopedically magnetized (i.e., with a mass-to-flux ratio that is spatially constant). The two theorems concerning magnetic forces in
Self-similar Collapse of Rotating Magnetic Molecular Cloud Cores
We present self-similar solutions that describe the gravitational collapse of rotating, isothermal, magnetic molecular cloud cores. These solutions make it possible, for the first time, to study the
Self-Similar Gravitational Collapse of Radiatively Cooling Spheres*
A new self-similar solution describing spherical implosions of a gaseous sphere under both self-gravity and radiative diffusion is investigated in detail, where the diffusivity is modeled by a power
Collapse of Singular Isothermal Spheres to Black Holes
We study the gravitational collapse of a relativistic singular isothermal sphere that is initially in unstable equilibrium. In the subsequent collapse, the dynamic spacetime is self-similar. The
Self-similar Champagne Flows in H II Regions
We consider the idealized expansion of an initially self-gravitating, static, singular, isothermal cloud core. For t ≥ 0, the gas is ionized and heated to a higher uniform temperature by the
Possibility of Core-envelope Separation in the Self-similar Dynamic Collapse of a Polytropic Filamentary Cloud
The core-envelope separation during the gravitational collapse is one of the important mechanisms in the binary formation that may occur in a rotating filamentary cloud. In this study, we consider
Self-similar Collapse of a Self-gravitating Viscous Disk
A self-similar solution for time evolution of isothermal, self-gravitating viscous disks is found under the condition that α' ≡ α(H/r) is constant in space (where α is the viscosity parameter and H/r
HIERARCHICAL GRAVITATIONAL FRAGMENTATION. I. COLLAPSING CORES WITHIN COLLAPSING CLOUDS
We investigate the Hierarchical Gravitational Fragmentation scenario through numerical simulations of the prestellar stages of the collapse of a marginally gravitationally unstable isothermal sphere
Formation and Collapse of Quiescent Cloud Cores Induced by Dynamic Compressions
We present numerical hydrodynamic simulations of the formation, evolution, and gravitational collapse of isothermal molecular cloud cores in spherical geometry. A compressive wave is set up in a
