Modelling the abundance structure of isocyanic acid (HNCO) toward the low-mass solar type protostar IRAS 16293-2422
Antonio Hernández-Gómez, Emna Sahnoun, Emmanuel Caux +5
Isocyanic acid (HNCO), the most stable of the simplest molecules containing the four main elements essential for organic chemistry, has been observed in several astrophysical envir…
SOLIS IV. Hydrocarbons in the OMC-2 FIR 4 region, a probe of energetic particle irradiation of the region
C. Favre, C. Ceccarelli, A. López-Sepulcre +16
We report new interferometric images of cyclopropenylidene, c-CH, towards the young protocluster OMC-2 FIR\,4. The observations were performed at 82 and 85 GHz with the NOr…
3D modelling of HCO and its isotopologues in the low-mass proto-star IRAS162932422
D. Quénard, S. Bottinelli, E. Caux +1
Ions and electrons play an important role in various stages of the star formation process. By following the magnetic field of their environment and interacting with neutral species…
Astrochemical evolution along star formation: Overview of the IRAM Large Program ASAI
B. Lefloch, R. Bachiller, C. Ceccarelli +27
Evidence is mounting that the small bodies of our Solar System, such as comets and asteroids, have at least partially inherited their chemical composition from the first phases of…
Detection of HOCO+ in the protostar IRAS 16293-2422
Liton Majumdar, Pierre Gratier, Valentine Wakelam +3
The protonated form of CO2, HOCO+, is assumed to be an indirect tracer of CO2 in the millimeter/submillimeter regime since CO2 lacks a permanent dipole moment. Here, we report the…
A revised distance to IRAS 162932422 from VLBA astrometry of associated water masers
S. A. Dzib, G. N. Ortiz-León, A. Hernández-Gómez +6
IRAS 16293-2422 is a very well studied young stellar system seen in projection towards the L1689N cloud in the Ophiuchus complex. However, its distance is still uncertain with a ra…
