Download or read book Formation Of The Solar System The Theories Old And New 2nd Edition written by Michael Mark Woolfson and published by World Scientific. This book was released on 2014-09-11 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully-updated second edition remains the only truly detailed exploration of the origins of our Solar System, written by an authority in the field. Unlike other authors, Michael Woolfson focuses on the formation of the solar system, engaging the reader in an intelligent yet accessible discussion of the development of ideas about how the Solar System formed from ancient times to the present.Within the last five decades new observations and new theoretical advances have transformed the way scientists think about the problem of finding a plausible theory. Spacecraft and landers have explored the planets of the Solar System, observations have been made of Solar-System bodies outside the region of the planets and planets have been detected and observed around many solar-type stars. This new edition brings in the most recent discoveries, including the establishment of dwarf planets and challenges to the ‘standard model’ of planet formation — the Solar Nebula Theory.While presenting the most up-to-date material and the underlying science of the theories described, the book avoids technical jargon and terminology. It thus remains a digestible read for the non-expert interested reader, whilst being detailed and comprehensive enough to be used as an undergraduate physics and astronomy textbook, where the formation of the solar system is a key part of the course.Michael Woolfson is Emeritus Professor of Theoretical Physics at University of York and is an award-winning crystallographer and astronomer.

Download or read book From Dust to Life written by John Chambers and published by Princeton University Press. This book was released on 2017-05-02 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The remarkable story of how our solar system came to be The birth and evolution of our solar system is a tantalizing mystery that may one day provide answers to the question of human origins. From Dust to Life tells the remarkable story of how the celestial objects that make up the solar system arose from common beginnings billions of years ago, and how scientists and philosophers have sought to unravel this mystery down through the centuries, piecing together the clues that enabled them to deduce the solar system's layout, its age, and the most likely way it formed. Drawing on the history of astronomy and the latest findings in astrophysics and the planetary sciences, John Chambers and Jacqueline Mitton offer the most up-to-date and authoritative treatment of the subject available. They examine how the evolving universe set the stage for the appearance of our Sun, and how the nebulous cloud of gas and dust that accompanied the young Sun eventually became the planets, comets, moons, and asteroids that exist today. They explore how each of the planets acquired its unique characteristics, why some are rocky and others gaseous, and why one planet in particular—our Earth—provided an almost perfect haven for the emergence of life. From Dust to Life is a must-read for anyone who desires to know more about how the solar system came to be. This enticing book takes readers to the very frontiers of modern research, engaging with the latest controversies and debates. It reveals how ongoing discoveries of far-distant extrasolar planets and planetary systems are transforming our understanding of our own solar system's astonishing history and its possible fate.

Book excerpt: The problem of the origin of the Moon is of fundamental importance to understanding the mechanism of the planetary solar system,Äôs formation. It is important to know the mechanism of differentiation of substances in a growing planet. When planets are formed from a cold protoplanetary cloud, the matter of the inner regions of the Earth and the Moon remains at temperatures lower than the melting point of iron. The main volume of the matter of the protoplanet remains in its unmelted state, and its differentiation occurs in the formed planet. In this work, attention is paid to the most important internal sources of energy: the decay energy of short-lived isotopes, the dissipation of tidal friction energy, and thermal energy from accidental deposition of bodies and particles on a growing surface. Accounting for these sources provides a solution to the problem.

Download or read book The Early Earth written by James Badro and published by John Wiley & Sons. This book was released on 2015-08-28 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.

Download or read book Planet Formation and Evolution in Our Solar System and Beyond written by John Brooks Biersteker and published by . This book was released on 2019 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of thousands of exoplanets in recent decades has revealed a remarkable diversity of planetary system architectures, including entire classes of planets for which there is no solar system analog. In particular, the Kepler mission has shown that planets intermediate in size between Earth and Neptune with orbital periods less than 100 days are abundant in our galaxy. Concurrently, spacecraft missions to small primitive bodies in our solar system have yielded valuable insights into conditions in the early solar system. This thesis addresses questions in planet formation theory arising from both sets of observations. We begin with an investigation into the observed diversity of super-Earth bulk densities, which range from being consistent with a terrestrial composition to requiring an extended hydrogen-helium (H/He) envelope comprising several percent of the planet's mass. Giant impacts are expected to play a role in the formation of these worlds. We examine the thermal consequences of such an impact, and find that atmospheric loss from these effects can significantly exceed that caused by the previously considered process of mechanical shocks for H/He atmospheres. Specifically, the energy released can produce a period of sustained, rapid mass loss through a Parker wind, partly or completely eroding the envelope. The degree of loss depends on planetary properties and the stochastic details of the impact, making giant impacts an attractive explanation for the observed diversity of super-Earth compositions. The final assembly of the terrestrial planets in our solar system likely also concluded with a period of giant impacts. We explore the significance of post-impact thermal losses for terrestrial planet atmospheres in different evolutionary states, finding that H/He envelopes are unlikely to survive the giant impact phase, but that secondary, outgassed envelopes with higher mean molecular weights may be retained. Atmospheric constituents with high mean molecular weights may be lost, however, if they are mixed into a predominantly H/He envelope. Next, this thesis examines magnetic measurements of comet 67P/Churyumov- Gerasimenko (67P) and their implications for the early solar system environment. Specifically, the remanent magnetization of solar system bodies reflects their accretion mechanism, the space environment in which they formed, and their subsequent geological evolution. We show that the Rosetta magnetometry requires very low bulk magnetizations of cometary material on spatial scales >/=10 cm. If 67P formed during the lifetime of the solar nebula and has not undergone significant subsequent alteration, this low magnetization is inconsistent with its formation from the gentle gravitational collapse of a cloud of millimeter-sized pebbles in a background magnetic field >/~3 [mu]T. This constraint is compatible with theories of magnetically driven evolution of protoplanetary disks. Lastly, this thesis presents the first attempt to determine an exoplanet's oblateness and obliquity through the use of changes in the transit depth caused by the spin precession of an oblate planet. Determination of these quantities would provide insights into a planet's internal structure and formation history. Using Kepler photometry, we examine the brown dwarf Kepler-39b and the warm Saturn Kepler-427b. We do not usefully constrain the oblateness of Kepler-39b, but we find transit depth variations for Kepler-427b at 90% significance consistent with a precession period of 5.5 years and an oblateness comparable to solar system gas giants.

Download or read book On the Origin of Planets written by M. M. Woolfson and published by World Scientific. This book was released on 2011 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book begins with a historical review of four major theories for the origin of the Solar System in particular, or of planets in general, which highlight the major problems that need to be solved by any plausible theory. In many theories, including that which form the major theme of this book, the formation of planets and stars is intimately linked, so four chapters are devoted to the processes that can be described as the birth, life and death of stars. Recent observations that have revealed the existence of planets around many Sun-like stars are described in detail, followed by a clear exposition of the Capture Theory for the origin of planets. Many aspects of this theory are illustrated with sophisticated computer modelling that convincingly demonstrates the plausibility of the theory. The Capture Theory is in complete accord with all observations, including the estimate it gives for the proportion of Sun-like stars with planets. It is the only theory that sits comfortably with all present observational and theoretical constraints. The general theory of planet formation does not explain the detailed structure of the Solar System. An early postulated collision of two major planets is shown to explain many disparate features of the Solar System the nature of the terrestrial planets, surface features of the Moon and its relationship with Earth, asteroids, comets and dwarf planets, the relationship between Neptune, Triton and Pluto and the characteristics of meteorites, including the isotopic anomalies found in them. The postulate of a planetary collision is given support by a 2009 NASA observation of the residue of such an event around a distant young star.
