An excellent handbook on the physics of interplanetary dust, a topic of interest not only to astronomers and space scientists but also to engineers. The following topics are covered in the book: historical perspectives; cometary dust; near-Earth environment; meteoroids and meteors; properties of interplanetary dust, information from collected samples; in situ measurements of cosmic dust; numerical modeling of the Zodiacal Cloud structure; synthesis of observations; instrumentation; physical processes; optical properties of interplanetary dust; orbital evolution of interplanetary dust; circumplanetary dust, observations and simple physics; interstellar dust and circumstellar dust disks. No doubt, the text will be regarded as the standard reference on interplanetary dust for many years to come.
THE THE KYOTO KYOTO COLLOQUIUM COLLOQUIUM It It has has almost almost become become a a tradition tradition to to periodically periodically review review the the progress progress of of our our knowledge knowledge of of interplanetary interplanetary dust dust at at an an interdisciplinary interdisciplinary level. level. After After the the Honolulu Honolulu (1967), (1967), Heidelberg Heidelberg (1975), (1975), Ottawa Ottawa (1979) (1979) and and Marseilles Marseilles (1984) (1984) meetings, meetings, it it was was decided decided to to hold hold a a meeting meeting specially specially devoted devoted to to the the Origin Origin and and Evolution Evolution of of Interplanetary Interplanetary Dust Dust in in Kyoto, Kyoto, Japan Japan on on 27-30 27-30 August August 1990. 1990. This This colloquium colloquium was was certainly certainly appropriate appropriate in in location, location, timing timing and and objective. objective. The The choice choice of of the the location location was was most most appropriate, appropriate, not not only only because because of of the the charm charm of of the the beautiful beautiful city city of of Kyoto, Kyoto, but but also also because because of of the the important important involvement involvement of of our our Japanese Japanese colleagues, colleagues, both both in in observations observations of of interplanetary, interplanetary, cometary, cometary, meteoritic, meteoritic, circumplanetary circumplanetary or or circumstellar circumstellar dust, dust, and and in in physico-chemical physico-chemical analysis analysis or or theoretical theoretical developments. developments.
Investigation of the interplanetary dust cloud is characterized by contributions from quite different methods and fields, such as research on zodiacal light, meteors, micrometeoroids, asteroids, and comets. Since the earth's environment and interplanetary space became accessible to space vehicles these interrelations are clearly evident and extremely useful. Space measurements by micrometeoroid detectors, for example, provide individual and eventually detailed information on impact events, which however are limited in number and therefore restricted in statistical significance. On the other hand, zodiacal light measurements involve scattered light from many particles and therefore provide global information about the average values of physical properties and spatial distribution of interplanetary grains. Additional knowledge stems from lunar samples and from dust collections in the atmosphere and in deep sea sediments. All these sources of complementary information must be put together into a synoptical synthesis. This also has to take into account dynamical aspects and the results of laboratory investigations concerning physical properties of small grains. Such considerable effort is not merely an academic exercise for a few specialists interested in the solar dust cloud. Since this same cloud exclusively allows direct in-situ acess to investigate extraterrestrial dust particles over a wide range of sizes and materials, it provides valuable information for realistic treatment of dust phenomena in other remote cosmic regions such as in dense molecular clouds, circumstellar dust shells, and even protostellar or protoplanetary systems.
Since the last joint IAU and COSPAR Colloquium in Gainesville in 1995, there have been dramatic changes in the field resulting from in-situ space experiments, Earth orbiting satellites and ground based observations. The brightest comet since the early years of the twentieth century, comet Hale-Bopp, appeared, giving an invaluable opportunity to see in action one great source of interplanetary dust. Similarly, the Leonid meteor shower has been at its most active since 1966, producing spectacular displays of meteors and allowing for an array of observational techniques, not available in 1966 to be used, while theory has also been refined to a level where very accurate predictions of the timing of meteor storms has become possible. Prior to the meeting a total eclipse of the Sun in South West England and North Europe was observed, traditionally a good opportunity to observe the Zodiacal cloud. The knowledge of the Near-Earth Asteroid population has also increased dramatically, with the increased study arising from the heightened awareness of the danger to Earth from such bodies. Extrasolar planets have been discovered since the last meeting and it is recognised that interplanetary dust in other Planetary Systems can now be studied. Since much of the dust observed in such systems is at a distance of order 100 AU from the star, this brings into focus the production of dust in the Edgeworth-Kuiper belt of our own system. Recent years have seen a recognition of the importance of dust originating outside our own system, that is now present in the near-Earth environment. As is always the case when great strides take place observationally, much theoretical work follows, and the same is true in this instance. While data about the planetary medium from Venus to Jupiter was beginning to be available at the meeting in 1995, the data from both Galileo and Ulysses have now been more fully analysed, with a corresponding increase in our knowledge. This book reflects the thematic approach adopted at the meeting, with a flow outwards (from meteors in the atmosphere, through zodiacal dust observation and interplanetary dust, to extra solar planetary systems) and returning (via the Edgeworth-Kuiper belt and comets) to the Earth, with laboratory studies of physical and chemical processes and the study of extra-terrestrial samples.
This monograph reports on the recent developments in the area of interplanetary and pre-solar dust grains. Chemical and isotope analyses of dust are discussed, especially with the aim to study the origin and evolution of interplanetary dust. Recent observations of extraterrestrial dust obtained with LDEF, Galileo and Ulysses are presented. Several velocity mechanisms for dust particles are discussed, in addition to their impact on cosmic or cometary dust grain capture devices. This volume is specially intended for research scientists and advanced (graduate) students in the fields of astronomy, astrophysics and geo and cosmochemists. Scientists in related fields, like the environmental sciences (especially researchers of artificial debris from rockets and boosters), are also likely to be interested in this work.
