IR diagnostics of embedded jets: kinematics and physical characteristics of the HH46-47 jet
Rebeca Garcia Lopez, Brunella Nisini, Jochen Eisloeffel +3
We present an analysis of the kinematics and physical properties of the Class I driven jet HH46-47 based on IR medium and low resolution spectroscopy obtained with ISAAC on VLT. Ou…
Spitzer spectral line mapping of protostellar outflows: I. Basic data and outflow energetics
David A. Neufeld, Brunella Nisini, Teresa Giannini +7
We report the results of spectroscopic mapping observations carried out toward protostellar outflows in the BHR71, L1157, L1448, NGC 2071, and VLA 1623 molecular regions using the…
Pre-Main Sequence variables in the VMR-D : identification of T Tauri-like accreting protostars through Spitzer-IRAC variability
T. Giannini, D. Lorenzetti, D. Elia +6
We present a study of the infrared variability of young stellar objects by means of two Spitzer-IRAC images of the Vela Molecular Cloud D (VMR-D) obtained in observations separated…
First detection of acceleration and deceleration in protostellar jets? Time variability in the Cha II outflows
A. Caratti o Garatti, J. Eislöffel, D. Froebrich +3
We present a multi-epoch (20 years baseline) kinematical investigation of HH52, 53, and 54 at optical and near-IR wavelengths, along with medium and high- resolution spectroscopic…
