On Radiation Pressure and the Poynting- Robertson Effect for Fluffy Dust Particles
Equation of motion for real dust particle under the action of electromagnetic radiation is more general than equation of motion corresponding to standardly used Poynting-Robertson effect (P-R effect). As a consequence, orbital evolution of particles may significantly differ from that corresponding to the P-R effect. The paper discusses recently published (Icarus, June 2002) derivation of equati...
متن کاملReal Dust Particles and Unimportance of the Poynting - Robertson Effect
The importance of the Poynting-Robertson effect on the motion of inter-planetary dust particles is discussed. Precise numerical calculations for real dust particle show that condition for the validity of the Poynting-Robertson effect is not fulfilled. The interaction of the (solar) electromagnetic radiation with really shaped dust particle is different from that which yields the Poynting-Robert...
متن کاملOn physics of the Poynting-Robertson effect
Detailed discussion of university textbook statements (Harwit 1988) concerning the Poynting-Robertson effect (P-R effect) is presented. Discussion is concentrated on better physical understanding of the P-R effect. References to complete correct equation of motion for real dust particle are also presented.
متن کاملThe Poynting-robertson Effect and Secular Changes of Orbital Elements
The Poynting-Robertson (P-R) effect has been applied to meteoroids for several decades. It is well known that the P-R effect produces only changes in the orbital plane of the particle. The differential equations governing the secular changes in both eccentricity and semi-major axis are known since the time of Robertson, provided the initial orbits are not near circular. A disadvantage of this t...
متن کاملThe Poynting-robertson Effect and Advancement of Perihelion
The Poynting-Robertson (P-R) effect has been applied to meteoroids – interplanetary dust particles – for several decades. It is well known that the P-R effect produces only changes in the orbital plane of the particle. Provided the initial orbits are not near circular, the differential equations governing the secular changes in both eccentricity and semimajor axis have been known since the time...
