Far-infrared laboratory spectroscopy of aminoacetonitrile and first interstellar detection of its vibrationally excited transitions
M. Melosso, A. Belloche, M. -A. Martin-Drumel +8
Aminoacetonitrile, a molecule detected in the interstellar medium only towards the star-forming region Sagittarius B2 (Sgr B2) thus far, is considered an important prebiotic specie…
First detection of NHD and ND in the interstellar medium
M. Melosso, L. Bizzocchi, O. Sipilä +7
Deuterium fractionation processes in the interstellar medium (ISM) have been shown to be highly efficient in the family of nitrogen hydrides. To date, observations were limited to…
High-resolution millimeter-wave spectroscopy of CHDCl: paving the way for future astronomical observations of chloromethane isotopologues
M. Melosso, A. Achilli, F. Tamassia +4
Chloromethane is the only organochloride detected in space to date. Its recent observation towards the low-mass protostar IRAS 16293-2422 with ALMA offers a prompt for new laborato…
An improved study of HCO+ and He system: interaction potential, collisional relaxation and pressure broadening
F. Tonolo, L. Bizzocchi, M. Melosso +4
In light of its ubiquitous presence in the interstellar gas, the chemistry and reactivity of the HCO+ ion requires special attention. The availability of up-to-date collisional dat…
Extensive ro-vibrational analysis of deuterated-cyanoacetylene (DCN) from millimeter-wavelengths to the infrared domain
M. Melosso, L. Bizzocchi, A. Adamczyk +12
Cyanoacetylene, the simplest cyanopolyyne, is an abundant interstellar molecule commonly observed in a vast variety of astronomical sources. Despite its importance as a potential t…
Molecular ions in L1544. I. Kinematics
P. Caselli, C. M. Walmsley, A. Zucconi +3
We have mapped the dense dark core L1544 in H13CO+(1-0), DCO+(2-1), DCO+(3-2), N2H+(1-0), NTH+(3-2), N2D+(2-1), N2D+(3-2), C18O(1-0), and C17O(1-0) using the IRAM 30-m telescope. W…
DCN observations towards high-mass star-forming regions
V. M. Rivilla, L. Colzi, F. Fontani +5
We present the study of deuteration of cyanoacetylene (HCN) towards a sample of 28 high-mass star-forming cores divided into different evolutionary stages, from starless to evo…
Molecular ions in L1544. II. The ionization degree
P. Caselli, C. M. Walmsley, A. Zucconi +3
The maps presented in Paper I are here used to infer the variation of the column densities of HCO+, DCO+, N2H+, and N2D+ as a function of distance from the dust peak. These results…
