# Envelope expansion with core collapse – I. Spherical isothermal similarity solutions

@article{Lou2004EnvelopeEW, title={Envelope expansion with core collapse – I. Spherical isothermal similarity solutions}, author={Yu-qing Lou and Yue Shen}, journal={Monthly Notices of the Royal Astronomical Society}, year={2004}, volume={348}, pages={717-734} }

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…
