# Self-similar shocks in polytropic gas flows around star-forming regions

@article{Lou2006SelfsimilarSI, title={Self-similar shocks in polytropic gas flows around star-forming regions}, author={Yu-qing Lou and Yang Gao}, journal={Monthly Notices of the Royal Astronomical Society}, year={2006}, volume={373}, pages={1610-1618} }

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 similarity shock across the sonic critical curve with an inner free-fall core collapse and a simultaneous outer expansion of the extended envelope; the separation or stagnation surface between these two flow zones travels outwards in a self-similar manner at a variable speed. One readily obtains accretion…
