A tale of two isotopes: Spatial variation in HCN fractionation toward young cores
Sigurd S. Jensen, Silvia Spezzano, Olli Sipilä +3
Context. Isotopic fractionation can serve as a powerful tracer of the chemical evolution during star and planet formation. To accurately interpret observations, it is crucial to id…
Chemical Complexity in the Early Stages of Star Formation in the SKAO Era
Eleonora Bianchi, Mathilde Bouvier, Claudio Codella +44
About 350 molecules have been identified in the interstellar medium (ISM), including complex molecules relevant to prebiotic chemistry. A remarkable level of molecular diversity ha…
The GUAPOS project: G31.41+0.31 Unbiased ALMA sPectral Observational Survey -- I. Isomers of CHO
C. Mininni, M. T. Beltrán, V. M. Rivilla +10
Understanding the degree of chemical complexity that can be reached in star-forming regions, together with the identification of precursors of the building blocks of life in the in…
No nitrogen fractionation on 600 au scale in the Sun progenitor analogue OMC-2 FIR4
F. Fontani, G. Quaia, C. Ceccarelli +8
We show the first interferometric maps of the 14N/15N ratio obtained with the Atacama Large Millimeter Array (ALMA) towards the Solar-like forming protocluster OMC-2 FIR4. We obser…
First interferometric study of enhanced N-fractionation in NH: the high-mass star-forming region IRAS 05358+3543
L. Colzi, F. Fontani, P. Caselli +3
Nitrogen (N) fractionation is used as a tool to search for a link between the chemical history of the Solar System and star-forming regions. A large variation of N/N…
Nitrogen fractionation in high-mass star-forming cores across the Galaxy
L. Colzi, F. Fontani, V. M. Rivilla +4
The fractionation of nitrogen (N) in star-forming regions is a poorly understood process. To put more stringent observational constraints on the N-fractionation, we have observed w…
Nitrogen and hydrogen fractionation in high-mass star forming cores from observations of HCN and HNC
L. Colzi, F. Fontani, P. Caselli +3
The ratio between the two stable isotopes of nitrogen, N and N, is well measured in the terrestrial atmosphere (), and in the pre-Solar nebula ().…
