Dust evolution by chemisputtering during protostellar formation Open
Dust grains play a crucial role in the modeling of protostellar formation, particularly through their opacity and interaction with the magnetic field. The destruction of dust grains in numerical simulations is currently modeled primarily b…

Performance of the double-Wien filter of the Neoma MC-ICPMS/MS with an application to copper stable isotope compositions Open
The new Neoma MC-ICPMS/MS is equipped with a prefiltering system consisting of a double-Wien filter and a collision/reaction cell whose performances are challenged using different combinations of magnetic and electrostatic field values and…

Size and density sorting of dust grains in SPH simulations of protoplanetary discs – II. Fragmentation Open
Grain growth and fragmentation are important processes in building up large dust aggregates in protoplanetary discs. Using a 3D two-phase (gas–dust) sph code, we investigate the combined effects of growth and fragmentation of a multiphase …
Elemental and isotopic variability in solar system materials by mixing and processing of primordial disk reservoirs Open
Isotope anomalies among planetary bodies provide key constraints on planetary\ngenetics and the Solar System's dynamical evolution. However, to unlock the\nfull potential of these anomalies for constraining the processing, mixing, and\ntra…
