We investigate self-similar dynamical processes in an isothermal self-gravitational fluid with spherical symmetry. With reference to the earlier complementary solution results of Larson, Penston, Shu, Hunter and Whitworth & Summers, we further explore the 'semi-complete solution space' from an initial instant t → 0 + to a final stage t → +∞. These similarity solutions can describe and accommodate physical processes of radial inflow, core collapse, oscillations and envelope expansion (namely… 
Spherical isothermal self-similar shock flows
We explore self-similar dynamical processes in a spherical isothermal self-gravitational fluid with an emphasis on shocks and outline astrophysical applications of such shock solutions. The previous
Shocked self-similar collapses and flows in star formation processes
We propose self-similar shocked flow models for certain dynamical evolution phases of young stellar objects, "champagne flows" of H II regions surrounding OB stars, and shaping processes of planetary
Envelope expansion with core collapse — II. Quasi-spherical self-similar solutions for an isothermal magnetofluid
We investigate self-similar magnetohydrodynamic (MHD) processes in an isothermal self-gravitating fluid with a quasi-spherical symmetry and extend the envelope expansion with core collapse (EECC)
Self-similar shocks in polytropic gas flows around star-forming regions
Self-similar shock solutions in spherically symmetric polytropic gas flows are constructed and analysed in contexts of protostar formation processes. Among other possible solutions, we model a
Envelope expansion with core collapse - III. Similarity isothermal shocks in a magnetofluid

With proper physical mechanisms of energy and momentum input from around the centre of a self-gravitating polytropic gas sphere, a central spherical ‘void’ or ‘cavity’ or ‘bubble’ of very much less
Outflows and Inflows in Astrophysical Systems
We seek for self-similar solutions describing the time-dependent evolution of self-gravity systems with either spherical symmetry or axisymmetric disk geometry. By assuming self-similar variable x ≡
3D perturbations in an isothermal self-similar flow
We explore three-dimensional (3D) isothermal perturbation structures in a non-linear dynamic background of self-gravitating isothermal radial flow with spherical symmetry. The overall flow then
New self-similar solutions of polytropic gas dynamics
We explore semicomplete self-similar solutions for the polytropic gas dynamics involving self-gravity under spherical symmetry, examine behaviours of the sonic critical curve and present new
Dynamic evolution model of isothermal voids and shocks
AbstractWe explore self-similar hydrodynamic evolution of central voids embedded in an isothermal gas of spherical symmetry under the self-gravity. More specifically, we study voids expanding at


Self-similar collapse of isothermal spheres and star formation.
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
Protostellar Collapse with a Shock
We reexamine both numerically and analytically the collapse of the singular isothermal sphere in the context of low-mass star formation. We consider the case where the onset of collapse is initiated
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
Gravitational collapse of an isothermal sphere
We investigate the spherical gravitational collapse of isothermal spheres using numerical hydrodynamics. The initial configuration is close to hydrostatic equilibrium. In the initial density profile

Growth of Perturbations in Gravitational Collapse and Accretion
When a self-gravitating spherical gas cloud collapses or accretes onto a central mass, the inner region of the cloud develops a density profile ρ ∝ r-3/2 and the velocity approaches free fall. We

Similarity solutions have been found for secondary infall and accretion onto an initially overdense perturbation in an Einstein--de Sitter (..cap omega.. = 1) universe. After the initial collapse of
Global Nonradial Instabilities of Dynamically Collapsing Gas Spheres
Self-similar solutions provide good descriptions for the gravitational collapse of spherical clouds or stars when the gas obeys a polytropic equation of state, p = Kργ (with γ ≤ 4/3, and γ = 1

We investigated the stability of similarity solutions for a gravitationally contracting isothermal sphere by means of a normal mode analysis. We found that a normal mode grows in proportion to (t0 -
