Jets from young stars IV: from models to observations and experiments

Research on astronomical jets has largely been conducted within the domain ofastronomical observations and astrophysical modeling and numerical simulations. However, the recent advent of high-energy density facilities has added experimental control to jet studies. Testing models for jet launching and collimation requires a highly interdisciplinary approach and sophistication. Indeed, closing the circle between pure magnetohydrodynamics, thermo-chemical evolution, high angular resolution spectro-imaging and laboratory experiments is not trivial. This volume seeks to bridge these gaps by providing a series of lectures linking the foundations of the discipline. Lectures presented in this book address - studies of jets physics in the laboratory - the magnetohydrodynamic theory of stationary jets - what we learn from coronal heating in the sun and from shock heating in molecular material and chemistry applied to heating mechanisms in magnetohydrodynamic jets - the atomic perspective on the microphysicsof the shocked material in the jets. The book closes by presenting a series of diagnostics making it possible to derive basic physical quantities from jet emission lines.
