Hunting pre-stellar cores with APEX: overview
P. Caselli, S. Spezzano, E. Redaelli +8
[Abridged] Pre-stellar cores are centrally concentrated starless cores on the verge of star formation and they represent the initial conditions for star and planet forma…
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…
Cosmic-ray ionisation rate in low-mass cores: the role of the environment
E. Redaelli, S. Bovino, G. Sabatini +6
Context: Cosmic rays drive several key processes for the chemistry and dynamical evolution of star-forming regions. Their effect is quantified mainly by means of the cosmic-ray ion…
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…
