A Solar System dust ring with the Earth as its shepherd

  title={A Solar System dust ring with the Earth as its shepherd},
  author={Albert A. Jackson and Herbert A. Zook},
Bodies orbiting in the gravitational fields of galactic, solar or planetary systems often suffer dissipative forces, including tidal interactions and drag resulting from motion through a gas or from collisions with dust grains. In the early solar nebula, gas drag induces resonance trapping, which may be of importance in the early accretional growth of planets1–3. By means of numerical integrations, we show here that small dust grains can be temporarily captured into exterior orbit-orbit… Expand
Structure of the Earth’s circumsolar dust ring
Interplanetary dust particles from comets and asteroids pervade the Solar System and become temporarily trapped into orbital resonances with Earth, leading to a circumsolar dust ring. Using theExpand
Orbital evolution of dust particles from comets and asteroids
Abstract In a computer simulation, dust grains of radius 10, 30, and 100 μm were released at perihelion passage from each of 35 different celestial bodies: 15 main belt asteroids, 15 short periodExpand
Dust grains in mean motion orbital resonances with a planet
Abstract The orbital evolution of interplanetary dust particles in the Solar System is governed by gravitational and non-gravitational forces. Non-gravitational effects become more significant withExpand
Size Dependence of Dust Distribution around the Earth Orbit
In the solar system, interplanetary dust particles (IDPs) originating mainly from asteroid collisions and cometary activities drift to Earth orbit due to Poynting–Robertson drag. We analyzed theExpand
Kuiper Belt Dust Grains as a Source of Interplanetary Dust Particles
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 thisExpand
Signatures of the Giant Planets Imprinted on the Edgeworth-Kuiper Belt Dust Disk
One method to detect extrasolar planetary systems is to deduce the perturbations of planets on the observed circumstellar dust disks. Our solar system, with its known configuration of planets,Expand
The Transit Light Curve of an Exozodiacal Dust Cloud
Planets embedded within debris disks gravitationally perturb nearby dust and can create clumpy, azimuthally asymmetric circumstellar ring structures that rotate in lock with the planet. The EarthExpand
Orbital Evolution of Retrograde Interplanetary Dust Particles and Their Distribution in the Solar System
Abstract 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 getExpand
Observational confirmation of a circumsolar dust ring by the COBE satellite
ASTEROID collisions are an important source of the dust particles in the zodiacal cloud1–3. These particles spiral in towards the Sun under the influence of drag forces4–6 and, in passing through theExpand
Trapping and dynamical evolution of interplanetary dust particles in Earth’s quasi-satellite resonance
Abstract We used numerical simulations to model the orbital evolution of interplanetary dust particles (IDPs) evolving inward past Earth’s orbit under the influence of radiation pressure,Expand


Orbital resonances in the solar nebula - Implications for planetary accretion
Abstract The influence of gas drag and gravitational perturbations by a planetary embryo on the orbit of a planetesimal in the solar nebula was examined. Non-Keplerian rotation of the gas causesExpand
Interplanetary dust dynamics. I. Long-term gravitational effects of the inner planets on zodiacal dust
Abstract Whereas the inner planets' perturbations on meteoroids' and larger interplanetary bodies' orbits have been studied extensively, they are usually neglected in studies of the dynamics ofExpand
Hyperbolic cosmic dust: Its origin and its astrophysical significance
Abstract The heliocentric radial distribution of the flux of hyperbolic cosmic dust particles, as measured by the Pioneer 8 and 9 spacecraft, is closely related to the radial variation of the spatialExpand
The formation and origin of the IRAS zodiacal dust bands as a consequence of single collisions between asteroids
Abstract The zodiacal dust bands discovered by IRAS can be explained as products of single collisions between asteroids. Debris from such a collision is distributed about the plane of the ecliptic asExpand
Orbital resonance in a dissipative medium
Abstract Orbital resonances tend to force bodies into noncircular orbits. If a body is also under the influence of an eccentricity-reducing medium, it will experience a secular change in semimajorExpand
Collisional balance of the meteoritic complex
Taking into account meteoroid measurements by in situ experiments, zodiacal light observations, and oblique angle hypervelocity impact studies, it is found that the observed size distributions ofExpand
Poynting-Robertson drag and orbital resonance
Both the Poynting-Robertson drag and resonant orbits appear to be very important for the motion of small grains in the early solar system. While orbital resonances are very often stable and tend toExpand
Extended sources of far-infrared emission superposed on the zodiacal and galactic backgrounds are found at high galactic latitudes and near the ecliptic plane. Clouds of interstellar dust at colorExpand
Resonance capture and the evolution of the planets
Abstract The present nearly resonant orbital periods of the planets are explained in terms of past two-body resonance capture of planetesimals in the solar nebula. Planetary formation then occursExpand
Radiation forces on small particles in the solar system
Abstract We present a new and more accurate expression for the radiation pressure and Poynting-Robertson drag forces; it is more complete than previous ones, which considered only perfectly absorbingExpand
