Empirical Diagnostics of Protoplanetary Disc Winds
Abstract
Disc winds play an important role in the evolution of protoplanetary systems, with photoevaporative winds in particular thought to be responsible for gas disc dispersal at late times. We present a new study of the observable diagnostics of these disc winds. We use both semi-analytic and numerical hydrodynamic models of disc winds, and compute observables such as free-free and forbidden line emission. We focus in particular on spatially-resolved observations (radio interferometry and optical/IR spectro-astrometry), and show how these techniques may allow us to measure disc mass-loss rates empirically. When combined with new observations (particularly from the VLT), these new diagnostics will allow us to build up a complete picture of how disc winds shape the evolution of planet-forming discs.
