Download or read book Development of a Numerical Simulation Method for Rocky Body Impacts and Theoretical Analysis of Asteroidal Shapes written by Keisuke Sugiura and published by Springer Nature. This book was released on 2020-03-17 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes numerical simulations of collisions between asteroids, based on a unique numerical code developed by the author. The code accurately solves the elastic dynamic equations and describes the effects of fracture and friction, which makes it possible to investigate the shapes of impact outcomes produced by asteroid collisions and subsequent gravitational accumulation of fragments. The author parallelizes the code with high parallelization efficiency; accordingly, it can be used to conduct high-resolution simulations with the aid of supercomputers and clarify the shapes of small remnants produced through the catastrophic destruction of asteroids. The author demonstrates that flat asteroids can only be produced by impacts involving objects with similar mass and low velocity, which suggests that the flat asteroids in our solar system were created in the planet formation era and have kept their shapes until today. The author also shows that asteroid collisions under certain conditions can produce the extremely elongated shape of an interstellar minor body, 1I/‘Oumuamua. In brief, the book offers a comprehensive investigation of asteroid impacts and shapes, making it a uniquely valuable resource.

Book excerpt: The Earth's Core, Second Edition is a six-chapter book that begins with the general physical properties of the Earth, with emphasis on the core-mantle boundary. This edition discusses the accretion mechanism, heat sources in the early Earth, time of core formation, thermal regime of the Earth, melting-point depth curves, and thermal consequences of iron-alloy core. Subsequent chapters focus on reversals of the Earth's magnetic field; the energetics and the constitution of the Earth's core; and the cores of the Moon and other planets. The role of the Earth's core is vital to the understanding of many geophysical phenomena. It is the seat of the Earth's magnetic field and is responsible as well to some variations in the length of the day.

Download or read book Planetary Systems Formation Evolution and Detection written by Bernard F. Burke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: `Are there other planetary systems like ours? Other planets like ours? Is there life elsewhere in the Universe?' So asks Dr. Lew Allen Jr. in the Foreword. In December of 1992, theorists, observers, and instrument builders gathered at the California Institute of Technology to discuss the search for answers to these questions. The International Conference, entitled `Planetary Systems: Formation, Evolution, and Detection' and supported through NASA's newly formed TOPS (Toward Other Planetary Systems) program, was the first of a series of conferences uniting researchers across disciplines and political boundaries to share thoughts and information on planetary systems. The conference was sponsored by NASA, hosted by JPL at Caltech, and endorsed by the 1992 International Space Year Association. These proceedings include discussions of topics ranging from stellar, disk, and planetary formation to new ways of searching for other stellar systems containing planets. The authors represent a wide range of nationalities, disciplines, and points of view. The second international conference took place in December of 1993.
Download or read book Neptune and Triton written by Dale P. Cruikshank and published by University of Arizona Press. This book was released on 1995-11 with total page 1292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first reconnaissance of all the major planets of the Solar System culminated in the Voyager 2 encounter with Neptune in August 1989. Neptune itself was revealed as a planet with gigantic active storms in its atmosphere, and off-center magnetic field, and a system of tenuous, lumpy rings. Whereas only two satellites were known prior to the encounter, Voyager discovered six more. Triton, the largest satellite, was revealed as a frozen, icy world with clouds and layers of haze, and with vertical plumes of particles reaching five miles into the thin atmosphere. This latest Space Science Series volume presents the current level of understanding of Neptune, its riings, and its satellites, derived from the data received from the Voyager. The book's chapters are written by the world's leading authorities on various aspects of the Neptune system and are based on papers presented at an international conference held in January 1992. Covering details of Neptune's interior, atmosphere, rings, magnetic fields, and near-space environment--as well as the small satellites and the remarkable moon Triton--this volume is a unique resource for planetary scientists and astronomers requiring a comprehensive analysis of Neptune viewed in the context of our knowledge of the other giant planets. Until another spacecraft is sent to Neptune, Neptune and Triton will stand as the basic reference on the planet.
Download or read book Astrophysics of Planet Formation written by Philip J. Armitage and published by Cambridge University Press. This book was released on 2020-01-30 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concise and self-contained, this textbook gives a graduate-level introduction to the physical processes that shape planetary systems, covering all stages of planet formation. Writing for readers with undergraduate backgrounds in physics, astronomy, and planetary science, Armitage begins with a description of the structure and evolution of protoplanetary disks, moves on to the formation of planetesimals, rocky, and giant planets, and concludes by describing the gravitational and gas dynamical evolution of planetary systems. He provides a self-contained account of the modern theory of planet formation and, for more advanced readers, carefully selected references to the research literature, noting areas where research is ongoing. The second edition has been thoroughly revised to include observational results from NASA's Kepler mission, ALMA observations and the JUNO mission to Jupiter, new theoretical ideas including pebble accretion, and an up-to-date understanding in areas such as disk evolution and planet migration.

Download or read book The Early Earth written by James Badro and published by John Wiley & Sons. This book was released on 2015-10-05 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Earth: Accretion and Differentiation provides a multidisciplinary overview of the state of the art in understanding the formation and primordial evolution of the Earth. The fundamental structure of the Earth as we know it today was inherited from the initial conditions 4.56 billion years ago as a consequence of planetesimal accretion, large impacts among planetary objects, and planetary-scale differentiation. The evolution of the Earth from a molten ball of metal and magma to the tectonically active, dynamic, habitable planet that we know today is unique among the terrestrial planets, and understanding the earliest processes that led to Earth’s current state is the essence of this volume. Important results have emerged from a wide range of disciplines including cosmochemistry, geochemistry, experimental petrology, experimental and theoretical mineral physics and geodynamics. The topics in this volume include: Condensation of primitive objects in the solar nebula, planetary building blocks Early and late accretion and planetary dynamic modeling Primordial differentiation, core formation, Magma Ocean evolution and crystallization This volume will be a valuable resource for graduate students, academics, and researchers in the fields of geophysics, geochemistry, cosmochemistry, and planetary science.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 75 of Reviews in Mineralogy and Geochemistry addresses a range of questions that were articulated in May 2008 at the First Deep Carbon Cycle Workshop in Washington, DC. At that meeting 110 scientists from a dozen countries set forth the state of knowledge about Earth's carbon. They also debated the key opportunities and top objectives facing the community. Subsequent deep carbon meetings in Bejing, China (2010), Novosibirsk, Russia (2011), and Washington, DC (2012), as well as more than a dozen smaller workshops, expanded and refined the DCO's decadal goals. The 20 chapters that follow elaborate on those opportunities and objectives.
