Dust particles dynamics in the solar ring Original Research Article

A two-dimensional model is analyzed in order to study the dynamical behavior of dust particles which are localized near the Sun, in particular at 4 solar radii. The equation of motion which describes the dynamics includes several forces; gravitational, Lorentz and radiation pressure. Also sublimation and gas drags are taken into account. Electrostatic charge is not constant in this model and both collisional and Coulomb drags are included in the equation of motion. It has been assumed that the solar magnetic field is radial outside the source surface. Some numerical results of the equation of motion are presented.
