POISSON project - I - Emission lines as accretion tracers in young stellar objects: results from observations of Chamaeleon I and II sources
S. Antoniucci, R. Garcia Lopez, B. Nisini +8
We present the results of the analysis of LR optical-NIR spectra (0.6-2.4 um) of a sample 47 YSOs in the ChaI and II star-forming clouds. These data are part of the POISSON project…
The large-scale magnetic field and poleward mass accretion of the classical T Tauri star TW Hya
JF Donati, SG Gregory, SHP Alencar +9
We report here results of spectropolarimetric observations of the ~8Myr classical TTauri star (cTTS) TWHya carried out with ESPaDOnS at the Canada-France-Hawaii Telescope (CFHT) in…
Sub-arcsecond [FeII] spectro-imaging of the DG Tau jet: Periodic bubbles and a dusty disk wind?
V. Agra-Amboage, C. Dougados, S. Cabrit +1
We present SINFONI/VLT observations of the DG Tauri jet in the [FeII] lines with 0.15" angular resolution and R=3000 spectral resolution. We observe an onion-like velocity structur…
The Bipolar X-Ray Jet of the Classical T Tauri Star DG Tau
M. Guedel, M. Audard, F. Bacciotti +18
We report on new X-ray observations of the classical T Tauri star DG Tau. DG Tau drives a collimated bi-polar jet known to be a source of X-ray emission perhaps driven by internal…
