Effects of a clumpy circumstellar medium on the dynamics of stellar winds

Abstract:Mass pickup from clumps resulting from previous mass loss phases by a fast stellar wind can substantially modify its behaviour, even leading to a highly supersonic wind becoming transonic before leaving the mass-loading region. The observational consequences of mass-loading on these astrophysical flows is discussed.
Keywords:hydrodynamics  stars: mass-loss  ISM: kinematics and dynamics  planetary nebulae
