  "abstract": "Aims. 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, we need an interpretable model that reproduces the observed spectra. Methods. We designed a differentiable 3D geometrical model that produces synthetic observations from the parameterized density and velocity fields, and that can be efficiently optimized to reproduce the real data cubes. The model has been applied to p -NH 2 D and N 2 D + spectral cubes in the prestellar core L1544. Results. The optimized model suggests that to reproduce the observed velocity difference between p -NH 2 D and N 2 D + in L1544, an asymmetric structure in density and velocity is necessary.",
