Query: Jets from Young Stars   Jets are ubiquitous in the Universe and, as demonstrated in this volume, are
seen from a large number of astrophysical objects. For a number of reasons, in
particular their proximity and the abundant range of diagnostics to determine
their characteristics, jets from young stars and their associated outflows may
offer us the best opportunity to discover how jets are generated in general and
the nature of the link between outflows and their accretion disks. Recently it
has become clear that jets may be fundamental to the star formation process in
removing angular momentum from the surrounding protoplanetary disk thereby
allowing accretion to proceed. Moreover, with the realisation that planetary
formation begins much earlier than previously thought, jets may also help forge
planets by determining initial environmental characteristics. This seems to be
particularly true within the so-called terrestrial planet forming zone. Here we
review observations of jets from young stars which have greatly benefitted from
new facilities such as ALMA, space observatories like Spitzer, Herschel and
HST, and radio facilities like LOFAR and the VLA. Interferometers such as CHARA
and GRAVITY are starting to make inroads into resolving how they are launched,
and we can look forward to a bright future in our understanding of this
phenomenon when JWST and the SKA come on stream. In addition, we examine the
various magnetohydrodynamic models for how jets from young stars are thought to
be generated and how observations may help us select between these various
options.
