T Tauri Jet Physics Resolved Near The Launching Region with the Hubble Space Telescope
Deirdre Coffey, Francesca Bacciotti, Linda Podio
We present an analysis of the gas physics at the base of jets from five T Tauri stars based on high angular resolution optical spectra, using the Hubble Space Telescope Imaging Spe…
Jet rotation: launching region, angular momentum balance and magnetic properties in the bipolar outflow from RW Aur
Jens Woitas, Francesca Bacciotti, Thomas P. Ray +3
Using STIS on board the HST we have obtained a spectroscopic map of the bipolar jet from RW Aur. We find signatures of rotation within the first 300 AU of the jet (1.''5 from RW Au…
The Evolution and Simulation of the Outburst from XZ Tauri - A Possible EXor?
Deirdre Coffey, Turlough P. Downes, Thomas P. Ray
We report on multi-epoch HST/WFPC2 images of the XZ Tauri binary, and its outflow, covering the period from 1995 to 2001. Data from 1995 to 1998 have already been published in the…
Rotation of Jets from Young Stars: New Clues from the Hubble Space Telescope Imaging Spectrograph
Deirdre Coffey, Francesca Bacciotti, Jens Woitas +2
We report findings from the first set of data in a current survey to establish conclusively whether jets from young stars rotate. We observed the bi-polar jets from the T Tauri sta…
