Envelope expansion with core collapse – I. Spherical isothermal similarity solutions
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,
Self-similar dynamics of a magnetized polytropic gas
Abstract In broad astrophysical contexts of large-scale gravitational collapses and outflows and as a basis for various further astrophysical applications, we formulate and investigate a theoretical
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)

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
General polytropic self-gravitating cylinder free-fall and accreting mass string with a chain of collapsed objects
We present a theoretical model framework for general polytropic (GP) hydrodynamic cylinder under self-gravity of infinite length with axial uniformity and axisymmetry. For self-similar dynamic
Numerical simulations of isothermal collapse and the relation to steady-state accretion

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
Dynamic voids surrounded by shocked conventional polytropic gas envelopes
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
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
