Methanol emission from low mass protostars
S. Maret, C. Ceccarelli, A. G. G. M. Tielens +5
We present observations of methanol lines in a sample of Class 0 low mass protostars. Using a 1-D radiative transfer model, we derive the abundances in the envelopes. In two source…
Sulphur chemistry and molecular shocks: the case of NGC1333-IRAS2
Valentine Wakelam, Cecilia Ceccarelli, Alain Castets +5
We present SO and SO2 observations in the region of the low mass protostar IRAS2/NGC1333. The East-West outflow originating from this source has been mapped in four transitions of…
Sulphur-bearing species in the star forming region L1689N
V. Wakelam, A. Castets, C. Ceccarelli +3
We report observations of the expected main S-bearing species (SO, SO2 and H2S) in the low-mass star forming region L1689N. We obtained large scale (~300''x200'') maps of several t…
