A submillimeter line survey of low-mass protostars: prelude to ALMA and Herschel
E. F. van Dishoeck, J. K. Joergensen, S. Maret +5
The results from a single-dish molecular line survey of a set of 18 deeply embedded young stellar objects are summarized. More than 40 lines from 16 different species were observed…
HDO abundance in the envelope of the solar-type protostar IRAS16293-2422
B. Parise, E. Caux, A. Castets +12
We present IRAM 30m and JCMT observations of HDO lines towards the solar-type protostar IRAS 16293-2422. Five HDO transitions have been detected on-source, and two were unfruitfull…
Complex molecules in the hot core of the low mass protostar NGC1333-IRAS4A
Sandrine Bottinelli, Cecilia Ceccarelli, Bertrand Lefloch +7
We report the detection of complex molecules (HCOOCH_3, HCOOH and CH_3CN), signposts of a "hot core" like region, toward the low mass, Class 0 source NGC1333-IRAS4A. This is the se…
Resetting chemical clocks of hot cores based on S-bearing molecules
Valentine Wakelam, Paola Caselli, Cecilia Ceccarelli +2
We report a theoretical study of sulphur chemistry, as applied to hot cores, where S-bearing molecular ratios have been previously proposed and used as chemical clocks. As in previ…
