Velocities and Rotational Rates of Interstellar Dust Grains
Interstellar dust grains exhibit complex dynamics which is essential for understanding many key interstellar processes that involve dust, including grain alignment, grain growth, grain shattering etc. Grain rotational and translational motions are affected not only by gaseous collisions, but also by interactions with ions, photons, magnetic fields etc. Some of those interactions, e.g. interacti...
متن کاملOptical and Magnetic Properties of Dust Grains
The optical and magnetic properties of dust grains are reviewed , as they relate to the problem of interstellar grain alignment. Grain geometry plays an important role in determining the optical properties , and scattering and absorption of starlight will produce radiative torques which may drive grains to suprathermal rates of rotation in in-terstellar clouds; these radiative torques appear li...
متن کاملMagnetic Dipole Microwave Emission from Dust Grains
Thermal fluctuations in the magnetization of interstellar grains will produce magnetic dipole emission at ν ∼< 100 GHz. We show how to calculate absorption and emission from small particles composed of material with magnetic as well as dielectric properties. The Kramers-Kronig relations for a dusty medium are generalized to include the possibility of magnetic grains. The magnetic permeability a...
متن کاملRotational modes of oscillation of rodlike dust grains in a plasma.
Three dimensional rotatory modes of oscillations in a one-dimensional chain of rodlike charged particles or dust grains in a plasma are investigated. The dispersion characteristics of the modes are analyzed. The stability of different equilibrium orientations of the rods, phase transitions between the different equilibria, and a critical dependence on the relative strength of the confining pote...
متن کاملSelf-Diffusion of Dust Grains in Strongly Coupled Dusty Plasma Using Molecular Dynamics Simulation
In this paper diffusion of dust particles in strongly coupled dusty plasma is investigated by using molecular dynamics simulations. Self-diffusion coefficients of complex plasmas are obtained for a wide range of plasma parameters using Green-Kubo expression which is based on integrated velocity autocorrelation function (VACF). It is assumed that dust particles interact with each other by Yukawa...
