Gas phase Elemental abundances in Molecular cloudS (GEMS) I. The prototypical dark cloud TMC 1
A. Fuente, D. Navarro, P. Caselli +30
GEMS is an IRAM 30m Large Program whose aim is determining the elemental depletions and the ionization fraction in a set of prototypical star-forming regions. This paper presents t…
Water and interstellar complex organics associated with the HH 212 protostellar disc - On disc atmospheres, disc winds, and accretion shocks
C. Codella, E. Bianchi, B. Tabone +14
The HH 212 protostellar system, in Orion B, has been mapped thanks to ALMA-Band 7 Cycle 1 and Cycle 4 observations of dueterated water (HDO) and acetaldehyde (CHCHO) emission w…
Kinematics of dense gas in the L1495 filament
A. Punanova, P. Caselli, J. E. Pineda +4
We study the kinematics of the dense gas of starless and protostellar cores traced by the N2D+(2-1), N2H+(1-0), DCO+(2-1), and H13CO+(1-0) transitions along the L1495 filament and…
Discovery of the elusive radical NCO and confirmation of H2NCO+ in space
N. Marcelino, M. Agundez, J. Cernicharo +2
The isocyanate radical (NCO) is the simplest molecule containing the backbone of the peptide bond, C(=O)-N. This bond has a prebiotic interest since is the one linking two amino ac…
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 interstellar HCS and its metastable isomer HSC: new pieces in the puzzle of sulfur chemistry
M. Agundez, N. Marcelino, J. Cernicharo +1
We present the first identification in interstellar space of the thioformyl radical (HCS) and its metastable isomer HSC. These species were detected toward the molecular cloud L483…
