Shock Waves in Outflows from Young Stars
Hartigan, P. (Rice)
This review focuses on physics of the cooling zones
behind radiative shocks and the emission line
diagnostics that can be used to infer physical
conditions and mass loss rates in jets from young stars.
Spatial separations of the cooling zones from the shock fronts,
now resolvable with HST, and recent evidence for C-shocks have greatly
increased our understanding of how shocks in
outflows interact with the surrounding medium
and with other material within the flow.
By combining multiple epoch HST images,
one can create `movies' of flows like those
produced from numerical codes, and learn what kinds
of instabilities develop within these systems.
