Title: Accretion and Outflow from Young Stellar Disks
Abstract:
We aim to monitor T Tauri star disk emission features and jet outflow
morphologies to determine how these features vary with disk accretion rate,
and how and when the outflow responds to major accretion events. Young stars
are surrounded by circumstellar disks through which they accrete mass.
Magneto-centrifugal disk winds remove angular momentum from the inner region
and so allow accretion to proceed. These winds are magnetically collimated to
form stellar jets. We will determine a) how the disk chromosphere spectrum
changes with accretion rate, b) whether new clumps ejected in the outflow
result from major accretion events, and c) how jet clumps evolve as they move
along the jet channel.
