Abstract:
The disk-outflow connection is thought to play a key role in
extracting excess angular momentum from a forming proto-star. Although
jet rotation has been observed in a few objects, no rotation of
molecular outflows has been unambiguously reported so far.
We report new millimeter-interferometric observations of the edge-on
T-Tauri-star - disk system in the isolated Bok globule CB-26.
The aim of these observations was to study the disk-outflow relation
in this 1Myr old low-mass young stellar object.
Description:
The IRAM PdBI array was used to observe 12CO(2-1) at 1.3mm in two
configurations, resulting in spectral line maps with 1.5" resolution.
We use an empirical parameterized steady-state outflow model combined
with 2-D line radiative transfer calculations and chi2-minimization
in parameter space to derive a best-fit model and constrain parameters
of the outflow.
