Using the Moon to occult the Sun, the Clementine spacecraft used its navigation cameras to map the inner zodiacal light at optical wavelengths over elongations of 3 ε 30 o from the Sun. This surface brightness map is then used to infer the spatial distribution of interplanetary dust over heliocentric distances of about 10 solar radii to the orbit of Venus. The averaged ecliptic surface brightness...
The orbital evolution of interplanetary dust particles (IDPs) from both retrograde and prograde Halley-type comets is numerically simulated. It is found that dust particles nearly always get trapped into one or more mean motion resonances (MMRs) with giant planets while in retrograde orbits. Of the 1000 retrograde particles simulated 116 are trapped in MMRs that last longer than 100,000 years, and...
The three-dimensional orbital evolution of interplanetary dust particles in mean motion resonances (MMRs) with planets is investigated in a restricted three-body system. Using the time variation of the Jacobi “constant” due to drag forces, we develop simple analytical expressions that describe the orbital evolution of a dust grain in MMRs with a planet. Together with the time rate of change of the...
The recent discovery of the so-called Kuiper belt objects has prompted the idea that these objects produce dust grains that may contribute significantly to the interplanetary dust population. In this paper, the orbital evolution of dust grains, of diameters 1 to 9 μm, that originate in the region of the Kuiper belt is studied by means of direct numerical integration. Gravitational forces of the Sun...
In the all sky survey by the Infrared Astronomical Satellite in 1983, eight comets were discovered to have dust trails (Sykes, M. V., and R. G. Walker 1992.Icarus95, 180–210). Among those eight comets, the most prominent trail belonged to Tempel 2, suggesting that this comet recently has been the most prolific producer of interplanetary dust. A numerical simulation of the orbital evolution of 4- and...
In this paper, we examine the effects of radiation pressure, Poynting-Robertson (PR) drag, and solar wind drag on dust grains trapped in mean motion resonances with the Sun and Jupiter in the restricted (negligible dust mass) three-body problem. We especially examine the evolution of dust grains in the 1:1 resonance. As a first step, the Sun and Jupiter are idealized to both be in circular orbit about...
We have studied the orbital evolution of micrometer-sized asteroidal dust particles under the influence of planetary gravitational perturbations, radiation pressure, Poynting-Robertson (PR) drag, and solar wind drag. It is found that a significant fraction of the 2-μm diameter particles, with β = 0.26, are thrown into the 1:1 mean motion resonance zone with Jupiter when they are released from their...
