“…Papers by Klačka and Kocifaj (1994), Kocifaj et al (2000) and Kimura et al (2002) are based on the paper by Klačka (1994a), which hypothesized that quantities corresponding to components of space vector Q ′ ≡ (Q ′ 1 , Q ′ 2 , Q ′ 3 ) behave as scalars under Lorentz transformation. Our derivation proves correctness of the hypothesis.…”

“…Since real particles interact with electromagnetic radiation in a complicated manner and particles of various optical properties exist (e. g., Mishchenko et al 2002), it is essential to have an equation of motion sufficiently general to cover a wide range of optical parameters, not just the limited cases previously investigated. As an attempt of formulating such a general equation of motion, we can mention Lyttleton (1976), Klačka (1994a), Klačka and Kocifaj (1994), Kocifaj et al (2000). The last three presentations are of hypothetical character only, since none of them proves correctness of the equation of motion.…”

Abstract. 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 effect. Two subcases are considered: (i) central acceleration due to gravity and the radial component of radiation pressure independent of the particle velocity, (ii) central acceleration given by gravity and the radiation force as the disturbing force. The latter case yields results which may be compared with secular orbital evolution in terms of orbital elements for an arbitrarily shaped dust particle. The effects of solar wind are also presented.

The effect of stellar electromagnetic radiation on the motion of arbitrarily shaped dust particles in mean-motion orbital resonances with planets is investigated. Giving a resonance and a value of parameter β (the ratio between radiation pressure force and gravitational force of the central star), nonradial components of radiation pressure force are calculated when a given trajectory is prescribed. The found values of the nonradial components are in a good agreement with published detailed numerical simulations for a given nonspherical particle. Therefore nonspherical grains are present in mean-motion resonances with planets. Similarly, the difference between the motion of a real particle and the motion influenced by the Poynting-Robertson effect may be important.

“…η ≈ 1/3 for the Sun. The force caused by the solar wind is derived using the method presented in Klačka & Saniga (1993) and Klačka (1994). For details of the P-R effect, we refer to Poynting (1903), Robertson (1937) and Klačka (2008a,b) and Klačka et al (2009).…”

Eccentricity evolution of a dust particle in a mean motion orbital resonance with a planet in circular orbit is investigated. The action of solar electromagnetic and corpuscular radiation, including non-radial components of the solar wind velocity, is taken into account. Various types of eccentricity evolution depend on the angle between the radial direction and the direction of the solar wind velocity. The evolution changes at the analytically derived angles. Its application to exosolar systems is included.
