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

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 ...

The ways of establishing the extraterrestrial nature of different subsets of interplanetary dust collected in the stratosphere by high-altitude aircraft are discussed. Consideration is given to microanalytic techniques which make it possible to obtain detailed experimental information on the mineralogical and petrographic characteristics, the mid-IR ...

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.
