We study how the magnetorotational instability (MRI) in protoplanetary disks
is affected by the electric discharge caused by the electric field in the
resistive MHD. We have performed three-dimensional shearing box simulations
with various values ...

Geometrical cross sections of dust aggregates determine their coupling with
disk gas, which governs their motions in protoplanetary disks. Collisional
outcomes also depend on geometrical cross sections of initial aggregates. In
the previous paper,...

Rapid orbital drift of macroscopic dust particles is one of the major
obstacles against planetesimal formation in protoplanetary disks. We reexamine
this problem by considering porosity evolution of dust aggregates. We apply a
porosity model based...

Porosity evolution of dust aggregates is crucial in understanding dust
evolution in protoplanetary disks. In this study, we present useful tools to
study the coagulation and porosity evolution of dust aggregates. First, we

Mutual sticking of dust aggregates is the first step toward planetesimal
formation in protoplanetary disks. In spite that the electric charging of dust
particles is well recognized in some contexts, it has been largely ignored in
the current model...
