Available in PDF, EPUB and Kindle. Book excerpt: In the earliest stages of planet formation micrometer-sized dust grains collide and gradually build up kilometer-sized planetesimals, bodies that are so large that they can attract each other directly by gravity. This is an important landmark on the way to real planets because of the change to gravity-dominated growth. The road from boulders to planetesimals is however poorly known. Boulders have poor sticking properties and spiral into the young star due to the head wind from the slower rotating gas. This work presents the first detailed computer simulations of the motion of dust and boulders in turbulent protoplanetary discs. The turbulent diffusion coefficient of small dust grains is measured to be surprisingly high, whereas larger boulders concentrate by up to two orders of magnitude in transient high pressure regions that arise spontaneously in magnetorotational turbulence. The coupled motion of boulders and gas is found to be linearly unstable to the so-called streaming instability, leading to a turbulent state that is characterised by dense clumps of boulders that shield each other against the head wind of the gas.

Download or read book A Dialogue Concerning The Two Chief Models Of Planet Formation written by Michael Mark Woolfson and published by World Scientific. This book was released on 2017-05-22 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two models for the origin of the Solar System, the Nebula Theory and the Capture Theory, are discussed by protagonists, Simon and Steven respectively, in the presence of Solomon, who oversees the discussions. Modelled on Galileo's Dialogue Concerning the Two Chief World Systems, this book provides new insight into different theories of cosmogony.The Nebula Theory, at present the standard model of planet formation, proposes that a star and planets are derived from a single spinning nebula. Woolfson here introduces an alternative, the Capture Theory, in which planets are produced from a protostar tidally disrupted by a condensed star which 'captures' most of the formed planets into orbits. These complex ideas are simplified and presented in an easily understandable, accessible way for all students of physics, astronomy, cosmology and those interested in the beginning of our world as we know it.

Available in PDF, EPUB and Kindle. Book excerpt: Available with WebAssign! Author Theo Koupelis has set the mark for a student-friendly, accessible introductory astronomy text with In Quest of the Universe. He has now developed a new text to accommodate those course that focus mainly on planets and the solar system. Ideal for the one-term course, In Quest of the Solar System opens with material essential to the introductory course (gravity, light, telescopes, the sun) and then moves on to focus on key material related to our solar system. Incorporating the rich pedagogy and vibrant art program that have made his earlier books a success, Koupelis' In Quest of the Solar System is the clear choice for students making their way through their first astronomy course.

Download or read book Treatise on Geochemistry written by and published by Newnes. This book was released on 2013-10-19 with total page 14787 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!

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.

Available in PDF, EPUB and Kindle. Book excerpt: They range in size from microscopic particles to masses of many tons. The geologic diversity of asteroids and other rocky bodies of the solar system are displayed in the enormous variety of textures and mineralogies observed in meteorites. The composition, chemistry, and mineralogy of primitive meteorites collectively provide evidence for a wide variety of chemical and physical processes. This book synthesizes our current understanding of the early solar system, summarizing information about processes that occurred before its formation. It will be valuable as a textbook for graduate education in planetary science and as a reference for meteoriticists and researchers in allied fields worldwide.
