Corona Australis 151: an extremely young protostar
E. Redaelli, S. Spezzano, P. Caselli +9
Context. Prestellar cores are the birthplace of stars and planetary systems, but they are short-lived objects, since the initial stages of dense core evolution, collapse, and the f…
Probing the ion-neutral drift velocity towards the L1544 prestellar core: Detection of ambipolar diffusion using ND and para-NHD
Doris Arzoumanian, Silvia Spezzano, Tommaso Grassi +9
The dynamical role of the magnetic field in the star formation process is tightly linked to the coupling between matter and the field. This coupling is due to the interaction betwe…
Tracing the sulfur depletion in starless and pre-stellar cores
L. Schöller, S. Spezzano, O. Sipilä +4
Sulfur is one of the most abundant elements in the Universe, yet the sulfur budget inferred from the observed sulfur-bearing molecules in dense cores is significantly lower than ex…
A differentiable and optimizable 3D model for interpretation of observed spectral data cubes
T. Grassi, J. E. Pineda, S. Spezzano +6
Molecular spectral cubes of prestellar cores encode the information on the physical and chemical properties of these objects along the line of sight. To retrieve this information,…
New Estimate for the Cosmic Ray-Induced Photodissociation Rate in the Interstellar Medium
O. Sipilä, P. Caselli, M. Padovani +5
In the interstellar medium, cosmic rays (CRs) generate a field of ultraviolet (UV) photons via the excitation and subsequent radiative decay of molecules. This UV field i…
A 3D physico-chemical model of a pre-stellar core. I. Environmental and structural impact on the distribution of CHOH and -CH
S. S. Jensen, S. Spezzano, P. Caselli +2
Pre-stellar cores represent the earliest stage of the star- and planet-formation process. By characterizing the physical and chemical structure of these cores we can establish the…
