Interplanetary dust particles and meteoroids mostly originate from comets and asteroids.
Understanding their distribution in the Solar system, their dynamical behavior and their …

Context. The size of the constituent particles (monomers) of dust aggregates is one of the
most uncertain parameters directly affecting collisional growth of aggregates in planet …

Context. Dust grains coagulate to form dust aggregates in protoplanetary disks. Their
porosity can be extremely high in the disks. Although disk emission may come from fluffy …

We have used the Hubble Space Telescope Advanced Camera for Surveys coronagraph to
make the first polarization maps of the AU Microscopii debris disk. The polarization rises …

In protoplanetary disks, micron-sized dust grains coagulate to form highly porous dust
aggregates. Because the optical properties of these aggregates are not completely …

Dust coagulation in a protoplanetary disk is the first step in planetesimal formation. However,
the pathway from dust aggregates to planetesimals remains unclear. Both numerical …

We investigate the scattering and absorption of light by random ballistic aggregates of
spherical monomers. We present general measures for the size, shape, and porosity of an …

Aerosol opacity has emerged as a critical factor controlling transmission and emission
spectra. We provide a simple guideline for the effects of aerosol morphology on opacity and …

We study scattered-light properties of protoplanetary discs at near-infrared wavelengths for
various dust size and structure by performing radiative transfer simulations. We show that …

The analysis of the polarized light scattered by cometary dust particles provides information
on the physical properties of the solid component of cometary comae for C/1995 O1 Hale …
