Tracing the contraction of the pre-stellar core L1544 with HCO = 1-0 emission
J. Ferrer Asensio, S. Spezzano, P. Caselli +6
Spectral line profiles of several molecules observed towards the pre-stellar core L1544 appear double-peaked. For abundant molecular species this line morphology has been linked to…
Hyperfine resolved rate coefficients of HC17O+ with H2 (j = 0)
Francesca Tonolo, François Lique, Mattia Melosso +2
The formyl cation (HCO+) is one of the most abundant ions in molecular clouds and plays a major role in the interstellar chemistry. For this reason, accurate collisional rate coeff…
Nitrogen fractionation towards a pre-stellar core traces isotope-selective photodissociation
Silvia Spezzano, Paola Caselli, Olli Sipilä +1
Isotopologue abundance ratios are important to understand the evolution of astrophysical objects and ultimately the origins of a planetary system like our own. Being nitrogen a fun…
Molecular precursors of the RNA-world in space: new nitriles in the G+0.693-0.027 molecular cloud
Víctor M. Rivilla, Izaskun Jiménez-Serra, Jesus Martín-Pintado +10
Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for the origin of life. These chemical compounds could have been partially…
Deuteration of c-CH towards the pre-stellar core L1544
K. Giers, S. Spezzano, F. Alves +7
Context: In the centre of pre-stellar cores, the deuterium fractionation is enhanced due to the cold temperatures and high densities. Therefore, the chemistry of deuterated molecul…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. II. Methanol formation at low metallicity
F. Fontani, A. Schmiedeke, A. Sanchez-Monge +8
The outer Galaxy is an environment with metallicity lower than the Solar one and, because of this, the formation and survival of molecules in star-forming regions located in the in…
An Interferometric View of H-MM1. I. Direct Observation of NH3 Depletion
Jaime E. Pineda, Jorma Harju, Paola Caselli +14
Spectral lines of ammonia, NH, are useful probes of the physical conditions in dense molecular cloud cores. In addition to advantages in spectroscopy, ammonia has also been sug…
Precursors of the RNA-world in space: Detection of ()-1,2-ethenediol in the interstellar medium, a key intermediate in sugar formation
Víctor M. Rivilla, Laura Colzi, Izaskun Jiménez-Serra +20
We present the first detection of ()-1,2-ethenediol, (CHOH), the enol form of glycolaldehyde, in the interstellar medium towards the G+0.693-0.027 molecular cloud located in…
Mass ejection and time variability in protostellar outflows: Cep E. SOLIS XVI
A. de A. Schutzer, P. R. Rivera-Ortiz, B. Lefloch +46
Protostellar jets are an important agent of star formation feedback, tightly connected with the mass-accretion process. The history of jet formation and mass-ejection provides cons…
H2CS deuteration maps towards the pre-stellar core L1544
S. Spezzano, O. Sipilä, P. Caselli +7
Deuteration is a crucial tool to understand the complexity of interstellar chemical processes, especially when they involve the interplay of gas-phase and grain-surface chemistry.…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. I. Organic molecules and tracers of star-formation activity
F. Fontani, L. Colzi, L. Bizzocchi +8
The outer Galaxy is an environment with metallicity lower than the Solar one. Because of this, the formation and survival of molecules in star-forming regions located in the inner…
The Central 1000 au of a Pre-stellar Core Revealed with ALMA. II. Almost Complete Freeze-out
Paola Caselli, Jaime E. Pineda, Olli Sipilä +18
Pre-stellar cores represent the initial conditions in the process of star and planet formation. Their low temperatures (10 K) allow the formation of thick icy dust mantles, whic…
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…
