Magnetized Astrophysical Outflows: Cradle to Grave, Source to Effect

Abstract

We discuss the propagation of radiative MHD jets and outflows focusing on outflows driven by magneto-centrifugal rotators. Our goal is to link the properties of the jets with the physics of the sources which produce them. We find that density and magnetic field stratification (with radius) in jets from magnetized rotators leads to new behavior including the development of a dense inner jet core and a low density collar. We also report on more general studies of ambipolar diffusion and field geometry in pulsed jets. Finally we describe a new work designed to study the effects of magnetized winds on circumstellar environments appropriate to YSOs and PNe.
