High sensitivity molecular line observations towards the L1544 pre-stellar core challenge current models
J. Ferrer Asensio, S. S. Jensen, S. Spezzano +4
The increased sensitivity and spectral resolution of observed spectra towards the pre-stellar core L1544 are challenging the current physical and chemical models. With the aim of f…

Mapping Synthetic Observations to Prestellar Core Models: An Interpretable Machine Learning Approach
T. Grassi, M. Padovani, D. Galli +6
Observations of molecular lines are a key tool to determine the main physical properties of prestellar cores. However, not all the information is retained in the observational proc…

Fractionation in young cores: Direct determinations of nitrogen and carbon fractionation in HCN
S. S. Jensen, S. Spezzano, P. Caselli +4
We aim to determine the N/N and C/C ratios for HCN in six starless and prestellar cores and compare the results between the direct method using radiativ…
