Water ice deuteration: a tracer of the chemical history of protostars
Vianney Taquet, Phillip Peters, Claudine Kahane +5
Context. Millimetric observations have measured high degrees of molecular deuteration in several species seen around low-mass protostars. The Herschel Space Telescope, launched in…
Molecular abundances in the inner layers of IRC +10216
M. Agundez, J. P. Fonfria, J. Cernicharo +3
Observations towards IRC +10216 of CS, SiO, SiS, NaCl, KCl, AlCl, AlF, and NaCN have been carried out with the IRAM 30-m telescope in the 80-357.5 GHz frequency range. A large numb…
Herschel/HIFI observation of highly excited rotational lines of HNC toward IRC +10 216
F. Daniel, M. Agúndez, J. Cernicharo +6
We report the detection in emission of various highly excited rotational transitions of HNC (J = 6-5 through J =12-11) toward the carbon-star envelope IRC +10 216 using the HIFI in…
The submillimeter spectrum of deuterated glycolaldehydes
A. Bouchez, L. Margules, R. A. Motiyenko +5
Glycolaldehyde, a sugar-related interstellar prebiotic molecule, has recently been detected in two star-forming regions, Sgr B2(N) and G31.41+0.31. The detection of this new specie…
A study of deuterated water in the low-mass protostar IRAS16293-2422
Audrey Coutens, Charlotte Vastel, Emmanuel Caux +6
The HDO/H2O ratio is a powerful diagnostic to understand the evolution of water from the first stages of star formation to the formation of planets and comets. Our aim is to determ…
Formaldehyde and methanol deuteration in protostars: fossiles from a past fast high density pre-collapse phase
Vianney Taquet, Cecilia Ceccarelli, Claudine Kahane
Extremely high deuteration of several molecules have been observed around low mass protostars since a decade. Among them, formaldehyde and methanol present particularly high deuter…
