I review recent numerical and analytical work on the feedback from both low- and high-mass cluster stars into their gasoeus environment. The main conclusions are that i) outflow driving appears capabl...
A Fluid-Dynamical Subgrid Scale Model for Highly Compressible Astrophysical Turbulence
Fluid-Dynamical Subgrid Scale Model Highly Compressible Astrophysical Turbulence
