The B1 shock in the L1157 outflow as seen at high spatial resolution
M. Benedettini, S. Viti, C. Codella +7
We present high spatial resolution (750 AU at 250 pc) maps of the B1 shock in the blue lobe of the L1157 outflow in four lines: CS (3-2), CH3OH (3_K-2_K), HC3N (16-15) and p-H2CO (…
Broad N2H+ emission towards the protostellar shock L1157-B1
C. Codella, S. Viti, C. Ceccarelli +8
We present the first detection of N2H+ towards a low-mass protostellar outflow, namely the L1157-B1 shock, at about 0.1 pc from the protostellar cocoon. The detection was obtained…
The L1157 protostellar outflow imaged with the SMA
A. I. Gómez-Ruiz, N. Hirano, S. Leurini +1
We use the Submillimeter Array to observe, at 1.4 mm, the blue-lobe of the L1157 outflow at high spatial resolution (~ 3"). We detected SiO, H_2CO, and CH_3OH lines from several mo…
Evidence of a SiO collimated outflow from a massive YSO in IRAS 17233-3606
S. Leurini, C. Codella, A. Gusdorf +4
Studies of molecular outflows in high-mass young stellar objects reveal important information about the formation process of massive stars. We therefore selected the close-by IRAS…
