Chemical modeling of water deuteration in IRAS16293-2422
V. Wakelam, C. Vastel, Y. Aikawa +3
IRAS 16293-2422 is a well studied low-mass protostar characterized by a strong level of deuterium fractionation. In the line of sight of the protostellar envelope, an additional ab…
The origin of complex organic molecules in prestellar cores
Charlotte Vastel, Cecilia Ceccarelli, Bertrand Lefloch +1
Complex organic molecules (COMs) have been detected in a variety of environments, including cold prestellar cores. Given the low temperature of these objects, these last detections…
Water deuterium fractionation in the high-mass star-forming region G34.26+0.15 based on Herschel/HIFI data
Audrey Coutens, Charlotte Vastel, Ugo Hincelin +8
Understanding water deuterium fractionation is important for constraining the mechanisms of water formation in interstellar clouds. Observations of HDO and HO transitions…
High DO/HDO ratio in the inner regions of the low-mass protostar NGC1333 IRAS2A
Audrey Coutens, Jes Jørgensen, Magnus Persson +3
Water plays a crucial role both in the interstellar medium and on Earth. To constrain its formation mechanisms and its evolution through the star formation process, the determinati…
CH in absorption in IRAS16293-2422
S. Bottinelli, V. Wakelam, E. Caux +3
While recent studies of the solar-mass protostar IRAS16293-2422 have focused on its inner arcsecond, the wealth of Herschel/HIFI data has shown that the structure of the outer enve…
Detection of a dense clump in a filament interacting with W51e2
B. Mookerjea, C. Vastel, G. E. Hassel +8
In the framework of the Herschel/PRISMAS Guaranteed Time Key Program, the line of sight to the distant ultracompact HII region W51e2 has been observed using several selected molecu…
