Physics of Collective Dust-Dust Attraction and Dust Structure Formation

AIP Conference Proceedings, 2002
Collective attraction forces between two test dust grain in presence of many other dust grains are related with collective plasma flux. The basic state is formed by the balance of the plasma absorption on grains and plasma ionization. In the limit where the collective interaction dominates (a 2/ λ Di 2 >> Ti/Te ,a being the dust ...

Physics of Interplanetary and Interstellar Dust

Space Science Reviews, 1996
Observations 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

Physics and Pixie Dust

American Scientist, 2009
For many years, historians of the Re naissance have lauded the value of forg eries and fakes. Counterfeit documents, passed off as real, offer invaluable clues about the wider culture in which they were made. They iHuminate subtle, taken-for-granted assumptions and habits of the time; after all, forgers must have had particular ideas in mind about what

Physical Processes on Interplanetary Dust

2001
This chapter discusses physical processes affecting interplanetary dust grains, including processes determining dust formation, growth, disruption, and alteration. Computer simulations and laboratory studies of coagulation and aggregation show that mutual collisions between solid grains determine the growth of solid aggregates in the early solar system

Dust in tokamaks: An overview of the physical model of the dust in tokamaks code

Physics of Plasmas, 2010
The dynamical behavior of dust produced in tokamaks is an important issue for fusion. In this work, the current status of the dust in tokamaks (DTOKS) [J. D. Martin et al., Europhys Lett. 83, 65001 (2008)] dust transport code will be presented. A detailed description of the various elements of its underlying physical model will be given together with ...

Dust in jupiter's magnetosphere: Physical processes

Planetary and Space Science, 1980
Abstract The physical processes acting on charged microscopic dust grains in the Jovian magnetosphere are examined. Such small dust grains are believed to be injected continuously into the magnetosphere via volcanic activity on Io. It is shown that electromagnetic forces dominate the dust particle dynamics, and that these particles behave ...

Physics and Chemistry of Circumstellar Dust Shells

2013
Circumstellar dust, the astronomical dust that forms around a star, provides today's researchers with important clues for understanding how the Universe has evolved. This volume examines the structure, dynamics and observable consequences of the dust clouds surrounding highly evolved stars on the Giant Branch.

Physics and Astrophysics of Interstellar Dust

1978
Although this exposition covers the topics discussed in the series of lectures presented at the Summer School on Infrared Astronomy, their order has been changed. This is largely a result of the experience gained during the course. A number of results not presented in Erice have been included for completeness because there was inadequate time to do so ...
