Solar Radiation and Asteroidal Motion

TL;DR

This paper discusses how solar wind and electromagnetic radiation influence asteroid motion, providing complete equations of motion considering asteroid shape, surface properties, and proper reference frames, extending previous work.

Contribution

It presents a comprehensive equation of motion for asteroids affected by solar radiation, including shape and surface albedo effects, to first order in v/c, building on prior research.

Findings

Complete equations of motion considering electromagnetic effects

Inclusion of asteroid shape and surface albedo

Emphasis on proper reference frame calculations

Abstract

Effects of solar wind and solar electromagnetic radiation on motion of asteroids are discussed. The results complete the statements presented in Vokrouhlick\'{y} and Milani (2000). As for the effect of electromagnetic radiation, the complete equation of motion is presented to the first order in $v/c$ -- the shape of asteroid (spherical body is explicitly presented) and surface distribution of albedo should be taken into account. Optical quantities must be calculated in proper frame of reference.
