Investigating the origin and spectroscopic variability of the near-infrared HI lines in the Herbig star VV Ser
Rebeca García López, Ryuichi Kurosawa, Alessio Caratti o Garatti +5
The origin of the near-infrared (NIR) HI emission lines in young stellar objects are not yet understood. To probe it, we present multi-epoch LBT-LUCIFER spectroscopic observations…
Velocity and magnetic fields within 1000 AU from a massive YSO
A. Sanna, G. Surcis, L. Moscadelli +4
We want to study the velocity and magnetic field morphology in the vicinity (<1000 AU) of a massive young stellar object (YSO), at very high spatial resolution (10-100 AU). We perf…
AMBER/VLTI high spectral resolution observations of the Br emitting region in HD 98922. A compact disc wind launched from the inner disc region
A. Caratti o Garatti, L. V. Tambovtseva, R. Garcia Lopez +9
We analyse the main physical parameters and the circumstellar environment of the young Herbig Be star HD 98922. We present AMBER/VLTI high spectral resolution (R =12000) interferom…
Investigating 2MASS J06593158-0405277: a FUor burst in a triple system?
Alessio Caratti o Garatti, Rebeca Garcia Lopez, Tom P. Ray +7
FUor outbursts in young stellar objects (YSOs) are the most dramatic events among episodic accretion phenomena. The origin of these bursts is not clear: disk instabilities and/or d…
Probing the accretion-ejection connection with VLTI/AMBER: High spectral resolution observations of the Herbig Ae star HD163296
Rebeca Garcia Lopez, Larisa Tambovtseva, Dieter Schertl +4
Accretion and ejection are tightly connected and represent the fundamental mechanisms regulating star formation. However, the exact physical processes involved are not yet fully un…
