Electromagnetic Radiation and Motion of Dust Particle – A Simple Model
نویسنده
چکیده
A simple model for motion of dust particle (meteoroid) under the action of (solar) electromagnetic radiation is presented. The particle of the form of plane mirror is taken into account and exact analytical results are presented. As for long-term orbital evolution, particle may spiral outwards the central body (Sun); initial conditions are important. As a consequence, motion of real dust particles may differ from that generally considered.

Electromagnetic Radiation and Motion of Really Shaped Particle
Relativistically covariant form of equation of motion for real particle (neutral in charge) under the action of electromagnetic radiation is derived. Various formulations of the equation of motion in the proper frame of reference of the particle are used. Main attention is devoted to the reformulation of the equation of motion in the general frame of reference, e. g., in the frame of reference ...
متن کاملElectromagnetic Radiation and Motion of a Particle
We consider the motion of uncharged dust grains of arbitrary shape including the effects of electromagnetic radiation and thermal emission. The resulting relativistically covariant equation of motion is expressed in terms of standard optical parameters. Explicit expressions for secular changes of osculating orbital elements are derived in detail for the special case of the Poynting-Robertson ef...
متن کاملOrbital elements for motion of real particle under the action of electromagnetic radiation
Discussion of different types of osculating orbital elements for motion of real dust particle under the action of electromagnetic radiation in the central gravitational field is presented. It is shown that physically correct access is based on gravitational acceleration as the only radial acceleration – " radiation pressure " is not included in the radial acceleration.

Arguments of astronomers against equation of motion for arbitrarily shaped particle under action of electromagnetic radiation are discussed. Each of the arguments is commented in detail from the point of view of the required physics. It is shown that the arguments of astronomers, including referees in several astronomical and astrophysical journals, are unacceptable from the physical point of v...
متن کاملAberration of light and Motion of Real Particle
Correct and complete (to terms of v/c – v is particle's velocity, c is the speed of light) derivation of equation of motion for real dust particle under the action of electromagnetic radiation is derived. The effect of aberration of light is used. Equation of motion is expressed in terms of particle's optical properties, standardly used in optics for stationary particles.
