On the Dynamics of Interplanetary Dust Grains.
Abstract
The interaction of spherical grains of various materials whose radii lie in the micronic and submicronic range with the interplanetary medium is solved. This includes: (1) interaction with the solar radiation field which is solved using Mie scattering theory and taking into account the precise dependence of optical properties upon wavelength; (2) interaction with solar wind considering corpuscular tangential drag; and (3) interaction with the interplanetary magnetic field in terms of a diffusion or random walk through a series of electromagnetic scatterings. Numerical results for these interactions span in the entire solar system with elliptical orbits of grains of various materials and sizes and provide a clear global picture of dust grain interactions that includes grain dynamic considerations.
