Abstract

We discuss the application of meridionally self-similar models to winds and jets from hot coronae, in particular in the central region of accretion disks. A summary of how they may help understanding the evolution of jets from young stars is outlined. Then we discuss their application to the classification of AGN jets and extension to the relativistic regime of these exact axisymmetric solutions. Finally we discuss how it is possible to extend the polytropic equation of state and Parker winds to the relativistic regime to have a simple toy model for understanding thermal acceleration.
