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.

2007
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 ...

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.

Meteors and interplanetary dust
2008The contribution of meteor observations to our knowledge of meteoroids and interplanetary dust is reviewed under four headings — flux, mass distribution, physical structure and chemical composition. For lower limits of particle mass ranging from 1 g to 10−5 g the mean cumulative flux into the earth's atmosphere varies from 2 × 10−15 to 6 × 10−9 ...
