1 ANALYTICAL STUDIES OF MHD OUTFLOWS Self-similar solutions Outflows from stellar bodies From Solar Wind To Stellar winds (O  M stars) Compact objects (pulsars, …) AGN GRB From 1-D Hydro steady model (Parker 1958) To 3-D MHD relativistic time dep. codes Collimated flows: Steady and axisymmetric MHD approach

19 CONCLUSIONS Through the analysis of MHD steady solutions we can have insights on the physical properties of astrophysical outflows Further issues: Non ideal MHD (resistivity) Radiative effects (losses and/or acceleration) Large amplitute e.m. waves Time dependent solutions: Asympt. status, instabilities Interaction with the envir.
