Naturwissenschaften, 1979
Small sizes of individual particles and exceedingly low spatial density are formidable problems which greatly impeded progress in the dust field during the previous decade. The major experimental problems which prevented reliable measurements appear finally to have been solved and the entire dust field has seen dramatic progress over the past four ...

Physics of Interplanetary and Interstellar Dust
Space Science Reviews, 1996Observations of dust in the solar system and in the diffuse interstellar medium are summarized. New measurements of interstellar dust in the heliosphere extend our knowledge about micron-sized and bigger particles in the local interstellar medium. Interplanetary grains extend from submicron- to meter-sized meteoroids. The main destructive effect in the

Refractory Minerals in Interplanetary Dust
Science, 1986A newly studied interplanetary dust particle contains a unique set of minerals that closely resembles assemblages in the refractory, calcium- and aluminum-rich inclusions in carbonaceous chondrite meteorites. The set of minerals includes diopside, magnesium- aluminum spinel, anorthite, perovskite, and fassaite.

Motion of the Interplanetary Dust Cloud
Nature, 1970THERE have recently been several attempts1–3 to observe the motion of the interplanetary dust cloud by measuring the Doppler shift of the Hβ Fraunhofer line in the spectrum of the zodiacal light. From the variation of the Doppler shift with elongation it is possible in principle4 to deduce the way in which the particle number density varies with ...

Bismuth in interplanetary dust
Nature, 1984Samples of a large (∼60 µm) chondritic porous (CP) aggregate collected from the stratosphere have been analysed in detail by analytical electron microscopy (AEM). Previous studies of CP aggregates have shown that they are extraterrestrial in origin1–3 and may be related to cometary debris4.

Dust - Interplanetary And Interstellar
1973In the physical universe, perturbative clumpings of material include the entire spectrum of sizes from the subatomic to the metagalaxy. The span of masses from the electron to our Galaxy goes from 10-27 to 1044 gm, or 71 powers of 10. Between these two extremes, Nature displays a comprehensive array to the astronomer, as listed in Table 6-I.

Dust is finely dispersed solid material in interplanetary space. It derives from a number of sources: larger meteoroids, comets, asteroids, the planets, their satellites, and rings, and there is interstellar dust sweeping through the Solar System. These dust particles are also often called micrometeoroids, and range in size from assemblages of a few ...

Meteors and Interplanetary Dust
1977The business meeting was called to order at 10.00 on 28 August 1976. Approximately 30 members and guests were present. The President reported with regret the deaths of two commission members: Professor Astapovich of the USSR and Professor Olivier of USA. The meeting stood in silence for a few moments in their memory.

Abstract Scattered sunlight from interplanetary dust particles, mostly produced by comets and asteroids, orbiting the Sun are visible at dusk or dawn as the Zodiacal Cloud. Impacts onto the space-exposed surfaces of Earth-orbiting satellites indicate that, in the current era, thousands of tons of interplanetary dust enters the Earth’s
