End-to-end differentiable retrieval of molecular spectra using hydrodynamics, chemistry, and radiative transfer
T. Grassi, G. Vermariën, J. E. Pineda +3
We aim to reproduce observed molecular line emission using a pipeline that couples hydrodynamics, chemistry, and radiative transfer, capable of simultaneously optimizing all releva…
A tale of two isotopes: Spatial variation in HCN fractionation toward young cores
Sigurd S. Jensen, Silvia Spezzano, Olli Sipilä +3
The paper maps H13CN and HC15N in several young starless and pre‑stellar cores, finds that their column density ratio varies spatially and correlates with H2 column density, and sh…
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…
Jets and Outflows in Young Stellar Objects with the SKAO
Giovanni Sabatini, Gemma Busquet, Carlos Carrasco-González +48
Jets and outflows are ubiquitous phenomena associated with the formation of young stellar objects (YSOs). They play a crucial role in removing angular momentum from the accreting s…
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…
