Database of optical properties of cosmic dust analogues (DOP)
V. B. Il'in, N. V. Voshchinnikov, V. A. Babenko +8
We present a database containing information on different aspects of calculation and usage of the optical properties of small non-spherical particles -- cosmic dust analogues. The…
A new model of composite interstellar dust grains
N. V. Voshchinnikov, V. B. Il'in, Th. Henning +1
The approach to model composite interstellar dust grains, using the exact solution to the light scattering problem for multi-layered spheres as suggested by Voshchinnikov & Mathis…
In the Kitchen of Dust Modeling
N. V. Voshchinnikov
Dust grains have been detected in various astronomical objects. Interpretation of observations of dusty objects includes three components: 1) determination of the materials which c…
Modelling of Polarization Properties of Cometary Dust Grains
D. A. Semenov, N. V. Voshchinnikov
Observational data for dusty comets are summarized and systemized. The dependence of the linear polarization on various parameters (the phase angle, wavelength, etc.) is analyzed.…
Scattering and Polarization Properties of the Non-Spherical Particles
Nikolai V. Voshchinnikov
The albedo and dichroic polarization of spheroidal particles are studied. For the description of the phase function two asymmetry parameters and characterizing…
Circumstellar disc of beta Pictoris: constraints on grain properties from polarization
N. V. Voshchinnikov, E. Kruegel
We model the positional dependence of the optical polarization (BVRI-bands) in the circumstellar disc of beta Pictoris as observed by Gledhill et al. (1991) and Wolstencroft et al.…
