Constraints on accretion-ejection structures in young stars
Observatoire de Paris, France
This lecture reviews current observational constraints on theoretical models of accretion-driven ejection in young stars. Fundamental properties of jets (collimation scale, kinematics, variability, density, composition) and ejection/accretion ratios are presented and compared at various stages of star formation (Class 0, I, II). Mass-loss rate derivations and evidence for a broader wind component around the jet are also critically examined.
