We model the coagulation and fragmentation of dust grains during the protostellar collapse
with our newly developed shark code. It solves the gas-dust hydrodynamics in a spherical …

We propose a new evolutionary process for protoplanetary disks, the co-evolution of dust
grains and protoplanetary disks, revealed by dust–gas two-fluid non-ideal …

Dust grains influence many aspects of star formation, including planet formation and the
opacities for radiative transfer, chemistry, and the magnetic field via Ohmic, Hall, as well as …

Magnetic fields play an important role in the dynamics of present-day molecular clouds.
Recent work has shown that magnetic fields are equally important for primordial clouds …

Context. Whether or not magnetic fields play a key role in dynamically shaping the products
of the star formation process is still largely debated. For example, in magnetized protostellar …

Non-ideal magnetohydrodynamic (MHD) processes–namely Ohmic resistivity, ambipolar
diffusion, and the Hall effect–modify the early stages of the star formation process and the …

This paper investigates the impact of dust size distribution on magnetic resistivity. In
particular, we focus on its impact when the maximum dust size significantly increases from a …

We investigate the influence of dust particle size evolution on non-ideal
magnetohydrodynamic (MHD) effects during the collapsing phase of star-forming cores …

Context. Protostellar disks are the product of angular momentum conservation during
protostellar collapse. Understanding their formation is crucial because they are the …

Recent theoretical studies have suggested that a magnetic field may play a crucial role in
the first star formation in the universe. However, the influence of the magnetic field on the …
