The H2CO abundance in the inner warm regions of low mass protostellar envelopes
Sebastien Maret, Cecilia Ceccarelli, Emmanuel Caux +9
We present a survey of the formaldehyde emission in a sample of eight Class 0 protostars obtained with the IRAM and JCMT telescopes. The data have been analyzed with three differen…
First detection of triply-deuterated methanol
B. Parise, A. Castets, E. Herbst +4
We report the first detection of triply-deuterated methanol, with 12 observed transitions, towards the low-mass protostar IRAS 16293-2422, as well as multifrequency observations 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…
Water emission in NGC1333-IRAS4: Probing its surrounding envelope
S. Maret, C. Ceccarelli, E. Caux +2
Sun like stars are born from the collapse of fragment of molecular clouds. During the first embedded phase (the so called class 0/1), the protostar is surrounded by a collapsing en…
CO Depletion and Deuterium Fractionation in Prestellar Cores
Aurore Bacmann, Bertrand Lefloch, Cecilia Ceccarelli +3
We report the detection of D2CO in a sample of starless dense cores, in which we previously measured the degree of CO depletion. The deuterium fractionation is found extremely high…
