Planets in Binary Star Systems by Nader Haghighipour Pdf

In 1988, in an article on the analysis of the measurements of the variations in the radial velocities of a number of stars, Campbell, Walker, and Yang reported an - teresting phenomenon;the radial velocity variations of Cephei seemed to suggest the existence of a Jupiter-like planet around this star. This was a very exciting and, at the same time, very surprising discovery. It was exciting because if true, it would have marked the detection of the ?rst planet outside of our solar system. It was surprising because the planet-hosting star is the primary of a binary system with a separation less than 19 AU, a distance comparable to the planetary distances in our solar system. The moderatelyclose orbit of the stellar companionof Cephei raised questions about the reality of its planet. The skepticism over the interpretation of the results (which was primarily based on the idea that binary star systems with small sepa- tions would not be favorable places for planet formation) became so strong that in a subsequent paper in 1992, Walker and his colleagues suggested that the planet in the Cephei binary might not be real, and the variations in the radial velocity of this star might have been due to its chromospheric activities.

Planetary Habitability In Binary Systems by Pilat-lohinger Elke,Eggl Siegfried,Bazso Akos Pdf

Astrophysical research has led to the detection of thousands of planets outside the Solar System. About one-tenth of the extrasolar planets discovered so far reside in binary- or multi-stellar systems, and some of the closest known rocky exoplanets populate these multiple-star systems. While such environments seem good places to look for a second Earth, can Earth-like planets with two or more suns be habitable? And do solar system-like configurations have to be detected to find a habitable exo-Earth?This book addresses these questions. Starting with a brief overview of the various types of double star-planet configurations that have been observed so far, the book discusses the intriguing variety of planetary motion in such environments, taking into account the stellar type, evolution, and activity, and elaborates on how the presence of an additional stellar companion affects planet formation, system architectures and the habitability of planets in binary star systems. New methodologies developed in this area of research are explained and demonstrated for systems such as Alpha-Centauri, HD41004, Kepler-35, and many others. This monograph provides a grand entry to the exciting results that we expect from new missions like TESS, CHEOPS and Plato.

Star Core Zeus by Rupert D. Holms Pdf

STAR CORE ZEUS is a message for everybody on this planet. A dark massive object called 'star-core-zeus' has been discovered approaching our solar-system. It is responsible for the cycle of catastrophic climate change. Star-core-zeus is the remains of the former companion star of the Sun, which blew up in a supernova four point six billion years ago. The debris from this explosion not only provided the materials to build the planets; it was the origin of crude oil and complex organic molecules, which triggered Life on Earth. Two hundred and fifty million years ago, star-core-zeus flew so close to Earth that it ripped-off fifty percent of the old crust, simultaneously gouging out the ocean basins. Pangaea was not a super-continent; it was the fractured remains of the old surface of the whole Earth. The crust fragments launched into space by star-core-zeus became our Moon. Star-core-zeus travels in a very eccentric and steeply-inclined orbit, like an enormous comet. Every four thousand years, it passes the Sun then flies-by Earth, violently disturbing our planet. The whole solar-system is experiencing climate-change. The global-warming on Earth, Mars, Neptune and Triton is heralding the arrival of star-core-zeus. The location, flight-path and estimated time of arrival of star-core-zeus are described in this book. The front cover of the book is an image of star-core-zeus with its grid reference.

From Interacting Binaries to Exoplanets (IAU S282) by Mercedes T. Richards,Ivan Hubeny Pdf

In IAU Symposium 282, members of the exoplanet and binary star communities unite for the first time to discuss the state-of-the-art discovery, imaging, modeling and analysis tools used to study stars, brown dwarfs and exoplanets in multiple-object systems. They describe detection techniques using advanced telescopes and detectors, including the Kepler mission and the proposed Gaia and LSST projects. Imaging techniques discussed include adaptive optics, interferometry, polarimetry and tomography, while key modeling tools are covered in detail. Other topics include simulations of formation mechanisms in binary star systems, non-conservative evolution of binary stars, the formation and evolution of planets and a theory for the structure, atmospheres and evolution of giant exoplanets. The volume concludes with hydrodynamic simulations, models of planetary atmospheres and the habitability of exoplanets. These proceedings demonstrate how sophisticated modeling codes bridge the gap between theory and observations and increase our understanding of binary and multiple systems.

Binary and Multiple Systems of Stars by Alan H. Batten Pdf

Binary and Multiple Systems of Stars focuses on spectroscopic observational results and interpretations of binaries, and a few of multiple systems. Organized into 10 chapters, this book begins with the basic concepts and terminologies used in the study of binary and multiple systems of stars. Then, the incidence of both star systems is described. Subsequent chapters explore the properties of individual binaries, as well as the evolution and origin of such star system. This book will be a valuable reference material for astronomers, scientists in related fields, as well as graduate students.

Planets, Stars and Stellar Systems by Linda M. French,Paul Kalas Pdf

This is volume 3 of Planets, Stars and Stellar Systems, a six-volume compendium of modern astronomical research covering subjects of key interest to the main fields of contemporary astronomy. This volume on “Solar and Stellar Planetary Systems” edited by Linda French and Paul Kalas presents accessible review chapters From Disks to Planets, Dynamical Evolution of Planetary Systems, The Terrestrial Planets, Gas and Ice Giant Interiors, Atmospheres of Jovian Planets, Planetary Magnetospheres, Planetary Rings, An Overview of the Asteroids and Meteorites, Dusty Planetary Systems and Exoplanet Detection Methods. All chapters of the handbook were written by practicing professionals. They include sufficient background material and references to the current literature to allow readers to learn enough about a specialty within astronomy, astrophysics and cosmology to get started on their own practical research projects. In the spirit of the series Stars and Stellar Systems published by Chicago University Press in the 1960s and 1970s, each chapter of Planets, Stars and Stellar Systems can stand on its own as a fundamental review of its respective sub-discipline, and each volume can be used as a textbook or recommended reference work for advanced undergraduate or postgraduate courses. Advanced students and professional astronomers in their roles as both lecturers and researchers will welcome Planets, Stars and Stellar Systems as a comprehensive and pedagogical reference work on astronomy, astrophysics and cosmology.

Atomic Diffusion in Stars by Georges Michaud,Georges Alecian,Jacques Richer Pdf

The authors give an overview of atomic diffusion as applied to all types of stars, showing where it plays an essential role and how it can be implemented in modelling. Part I describes the tools that are required to include atomic diffusion in models of stellar interiors and atmospheres. An important role is played by the gradient of partial radiative pressure, or radiative acceleration, which is usually neglected in stellar evolution. In Part II, the authors systematically review the contribution of atomic diffusion to each evolutionary step. The dominant effects of atomic diffusion are accompanied by more subtle effects on a large number of structural properties throughout evolution. The goal of this book is to provide the means for the astrophysicist or graduate student to evaluate the importance of atomic diffusion in a given star. A fundamental physical process, atomic diffusion can significantly affect the superficial abundances of stars and/or their evolution. This guide includes all the information needed to take proper account of atomic diffusion's impact.
