Dust Plasma Interaction In Space

eBook Download

BOOK EXCERPT:

Dust is ubiquitous in the universe and responsible for stellar and planetary formation. Virtually all previous studies have considered the dust particulates to be a charge neutral component. Satellite missions such as Voyager revealed the extent to which charged dust plays a role in astrophysics. In most areas dust exists in the presence of a dilute plasma. In such a plasma environment the dust becomes charged to a variety of processes (eg photo-ionisation, collisions with electrons and ions, thermionic emission etc). Closer to home in the Earth's mesosphere, rocket measurements and radar observations conclusively demonstrate the importance of charged dust in forming complex structures responsible for Polar Mesospheric Summer Echoes. This book is the outcome of a periodic collaboration between a small group of scientists meeting twice a year at the International Space Science Institute (ISSI) in Bern, Switzerland over a period of three years. The book begins with a description of the fundamental physical processes which characterise dusty plasmas. Starting with charging and shielding of isolated dust particles in a plasma environment, the review progresses to non-linear dust dynamics of spherical and irregular dust. In an ensemble of a dust plasma system collective processes begin to manifest themselves in the form of new wave modes and instabilities which play an important role in the collective behaviour displayed in space and astrophysical environment. Finally more exotic topics, such as the Ising model for irregular dust grain alignment, classical Casimir forces and chargeons are explored.

Plasma Astrophysics And Space Physics

BOOK EXCERPT:

In May 1998 a hundred renowned scientists from 20 different countries met at the Max-Planck-Institut für Aeronomie to communicate their latest results and ideas in astrophysical and space plasma, as a follow-up to previous similar meetings which were held in Varenna, Abastumai, Potsdam, Toki and Guaruja. The main papers emerging from this meeting are collected in this volume. They deal with fundamental plasma phenomena, particle and radiation processes in astrophysics and space physics as the origin of magnetic activity, the basic mechanisms of particle acceleration and plasma heating common to plasma in galaxies and at the sun as well as in planetary magnetospheres. New observational results from YOHKOH, SOHO and other missions are presented. Using these, the basic physical processes leading to coronal heating and solar/stellar wind acceleration are discussed. Other topics are the microphysics of shock waves and transport phenomena in collisionless plasmas and the physics of thin plasma boundaries. The volume also treats the ionic composition of plasma and dust in the Universe and their observability in the solar system. A CD-ROM is attached which adds a valuable multimedia component, illuminating results of observations, theory and simulations. Everyone interested in astrophysical plasmas, its radiation and charged particle aspects, and advanced or even beginning students will find references to nearly all modern aspects of plasma astrophysics and space physics as well as an overview of current research results.

Waves In Dusty Space Plasmas

eBook Download

BOOK EXCERPT:

In this volume a thorough review is given of waves in dusty plasmas, a fascinating new domain combining plasmas and charged dust, two omnipresent ingredients of the Universe. Spokes and braids observed in the rings of Saturn cannot be explained by gravitation alone, but need the presence of charged dust. Other examples abound, as in zodiacal light, noctilucent clouds, comets and molecular clouds. After discussing charging mechanisms, supported by exciting new experiments, and space observations, the book describes extensions of known plasma modes covering the low frequencies typical for charged dust. Mixing detailed theoretical steps with summaries of expert contributions, a systematic multi-species treatment puts the literature in perspective, suitable also for newcomers. Typical complications like fluctuating dust charges, self-gravitational effects, and size distributions are dealt with, before ending with an outlook to future work and open questions. In this way, experts as well as interested newcomers will find a reliable guide, not just a compendium.

Frontiers In Dusty Plasmas

eBook Download

BOOK EXCERPT:

The study of dusty plasmas is now in a vigorous state of development. Dust and plasma coexist in a vast variety of cosmic environments and their research received a major boost in the early 80's with the Voyager spacecraft observations of peculiar features in the Saturnian ring system (e.g. the radial spokes) which could not be explained purely in gravitational terms. In addition, dust streams were measured by the Galileo spacecraft in the Jovian magnetosphere and charged dust in the earth's mesosphere was detected by a direct rocket experiment. Since then the area has greatly expanded with dedicated laboratory experiments verifying aspects of basic physics of charged dust grains in plasmas.These proceedings contain invited and poster papers which were presented by scientists active in the field from more than twenty countries. The material contains new aspects of collective interactions in dusty plasmas. For example, discoveries of dust-acoustic Mach cones, dust ion-acoustic shocks, great dust voids, vortex formation, dust crystallization under microgravity, coexistence of positive negative dust grains in the mesosphere and dust in tokamaks. The more theoretical and simulation studies focus on dynamical and structural properties and kinetic theories of strongly coupled dusty plasmas, as well as on self-organizations and structures, in addition to identifying forces (viz. wakefields, electrostatic and dipolar interactions etc.), which are responsible for charged dust grain attraction and phase transitions.The resulting book is a valuable, state-of-the-art review of the field of dusty plasma physics and will be welcomed by both researchers and graduate students who want to keep up to date in this rapidly growing field.

Solar And Space Physics

BOOK EXCERPT:

From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics--the disciplines NASA refers to as heliophysics--have yielded spectacular insights into the phenomena that affect our home in space. Solar and Space Physics, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized during the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily at NASA and the National Science Foundation for action, the report also recommends actions by other federal agencies, especially the parts of the National Oceanic and Atmospheric Administration charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in this report.
