We present experimental phase function and degree of linear polarization curves for seven samples cometary dust analogues namely: ground pieces Allende, DaG521, FRO95002 FRO99040 meteorites, Mg-rich olivine pyroxene, a sample organic tholins. The have been obtained at the IAA Cosmic Dust Laboratory wavelength 520 nm covering angle range from 3{\deg} to 175{\deg}. also provide values backscattering enhancement (BCE) our analogue samples. final goal this work is compare with observational data...

Abstract The effect of internal inhomogeneities and surface roughness on the scattering behavior large cosmic dust particles is studied by comparing model simulations with laboratory measurements. present work shows results an attempt to a sample measured in performed ray-optics code. We consider this as good analogue for interplanetary interstellar it shares its refractive index known materials these media. Several sensitivity tests have been both structural cases (internal inclusions...
We present experimental phase functions of three types millimeter-sized dust grains consisting enstatite, quartz and volcanic material from Mount Etna, respectively. The similar sizes but different absorbing properties. measurements are performed at 527 nm covering the scattering angle range 3 to 170 degrees. measured show two well defined regions i) soft forward peaks ii) a continuous increase with side- back-scattering regions. This behavior in agreement observed for Fomalhaut HR 4796A...
Abstract Lunar soil spectra differ from pulverized lunar rocks by reddening and darkening effects, shallower absorption bands. These effects have been described in the past as a consequence of space weathering. In this work, we focus on nanophase iron (npFe 0 ) inclusions experimental reflectance regolith particles. The are computed using SIRIS3, code that combines ray optics with radiative-transfer modeling to simulate light scattering different types scatterers. imaginary part refractive...
