Observational Constraints to Steady Jet Models in Young Stars

Abstract

Steady MHD models for protostellar jets (stellar winds, X-wind from the corotation radius, disk winds from an extended region) are critically examined against updated observational constraints. Synthetic model predictions are used whenever available. The origin of H2 cavities/jets in T Tauri stars is addressed and possible rotation signatures in sub-mm SiO jets are carefully re-examined.
