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…

Near-arcsecond resolution observations of the hot corino of the solar type protostar IRAS 16293-2422
Sandrine Bottinelli, Cecilia Ceccarelli, Roberto Neri +6
Complex organic molecules have previously been discovered in solar type protostars, raising the questions of where and how they form in the envelope. Possible formation mechanisms…

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…
