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.

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

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 ...

On the albedo of the interplanetary dust
Icarus, 1980The zodiacal light brightness and measured spatial density of the interplanetary dust lead to a mean geometric albedo of 0.24 for the dust particles near 1 AU; whereas the composition of collected micrometeroids suggests a geometric albedo of less than or approximately equal to 0.1. The data do not support the very low albedo (0.01 or less) proposed by

Radioactivity in interplanetary dust
Icarus, 1963Abstract Most of the radioactivity in interplanetary dust in the region of the Earth's orbit results from interactions with solar protons. The most abundant nuclides having half-lives longer than a few hours in a dust of chondritic composition are Co 56 , Fe 55 , Al 26 , Mn 53 , Co 55 , C 14 , Na 22 , and Co 57 .

Meteors and Interplanetary Dust
1994The organization of Commission 22 was disrupted by the untimely and much-lamented death of our President, Jan Stohl, in 1993 March. An appreciation of Jan appeared in the newsletter of the commission issued in 1993 April, and obituaries have been published in various other places.

Sources of interplanetary dust
2008Attention is centered on cosmic dust measures made by sensors on Pioneers 8 and 9 in Earth-like orbits. The conclusion follows Zook and Berg that the particles are largely “β-meteoroids,” interplanetary impact debris expelled by solar radiation pressure.
