Classical Novae
Author: Michael F. Bode
Publisher:
ISBN:
Category : Science
Languages : en
Pages : 368
Book Description
A comprehensive, up-to-date description of the properties and mechanisms of classical novae--and the first such effort in the subject since Payne-Gaposchkin's influential (but out of date) The Galactic Novae. Contributors present a balanced mix of observation and theory, and discuss information gathered at optical, radio, infrared, ultraviolet, and x-ray wavelengths. Discussion begins with an overview of the general properties of novae, then covers the accretion process in nova systems and the physics of the nova outburst. Classical novae are then placed in the broader family of cataclysmic variables. Final chapter is devoted to data on novae, including an atlas.

RS Ophiuchi (1985) and the Recurrent Nova Phenomenon
Author: M. F. Bode
Publisher: VSP
ISBN: 9789067640749
Category : Science
Languages : en
Pages : 276
Book Description
This international conference brought together over 50 astronomers from around the world. The meeting centred around a single object, the reccurent nova RS Ophiuchi, a star which had undergone four recorded outbursts before the latest event in 1985. Observations of previous outbursts (discussed in detail in one of the review talks) already indicated that RS Ophiuchi is a unique object of great astronomical significance. The outburst mechanism is probably similar to that of classical novae, but the interaction of the ejecta with a pre-existing shell of material give it the characteristics of a young supernova remnant. However, unlike supernova remnants, the evolution occurs 'before our very eyes'. Following the latest outburst, a frenzy of activity ensued, resulting in the acquisition of detailed observations from the radio (where rapidly expanding jets were discovered) to the X-ray (where RS Ophiuchi turned out to be one of the brightest soft X-ray sources yet observed). The Proceedings report the many exciting and unexpected observational results right across the electromagnetic spectrum in both RS Ophiuchi and related objects. Theoretical work on the cause of the outburst, and remnant evolution is also given prominence. The result is a much fuller understanding of RS Ophiuchi and its important standing in several branches of astrophysical research.

Novae and Related Stars

ISBN: 9401012172

Languages : en
Pages : 227
Book Description
Michael Friedjung Though known since antiquity, novae are still poorly under stood and present many problems. There has tended to be a lack of communication between theoreticians and observers and between different schools of thought, in spite of the advances of recent years in certain directions (observations of ordinary novae at minimum and of dwarf novae, theory of the causes of the explosion, etc ••• ). The meeting whose proceedings are contained in this volume was organized to stimulate a confron tation between the different ideas and results. The subject has changed a lot since 1963, when the previous international meeting was held. There were 61 participants at the conference from 17 countries, so very many groups ~oing research in the field of novae were represented. The reader will see that the subject has become more physical (we know for instance that the binary nature of novae is essential) but much work remains to be done. There is still a large gulf between theory and observation. May he find here many new ideas for future research! I would like to thank the French Centre National de la Recherche Scientifique for providing financial help. I must also thank the other members of the scientific committee (Profs and Drs Bath, Mustel, Payne-Gaposchkin, Sparks and Warner) and of the local committee (Audouze, Mrs Steinberg, Vauclair).

The Chemically Controlled Cosmos
Author: T. W. Hartquist
Publisher: Cambridge University Press
ISBN: 9780521419833
Category : Science
Languages : en
Pages : 208
Book Description
Simple chemistry governs a host of the exotic objects that populate our cosmos. For example, molecules in the early Universe acted as natural temperature regulators, keeping the primordial gas cool and, in turn, allowing galaxies and stars to form. What are the tools of the trade for the cosmic chemist and what can they teach us about the Universe we live in? These are the questions answered in this engaging and informative guide--the first book for nonspecialists on molecular astrophysics. In clear, nontechnical terms, and without formal mathematics, Hartquist and Williams show how to study and understand the behavior of molecules in a host of astronomical situations. Readers will learn about the secretive formation of stars deep within interstellar clouds; the origin of our own solar system; the cataclysmic deaths of many massive stars that explode as supernovae; and the hearts of active galactic nuclei, the most powerful objects in the universe. This book provides an accessible introduction to a wealth of astrophysics, and an understanding of how cosmic chemistry allows the investigation of many of the most exciting questions concerning astronomy today.

Book Description
4. Census of the Catalogue The catalogue contains information on 277 objects. 137 (50%) of them are stars whose outburst spectra or unambiguous mInImUm characteristics classify them as novae beyond doubt. 123 of them could be identified at minimum. 78 (28 %) are stars with amplitudes and light curve forms which makes nova classifi cation likely. 60 of them could be identified at minimum. Thus, 78 % ofthe objects in this catalogue are confirmed and suspected classical novae. 16 (6%) have properties compatible with both novae and related objects. 15 are identified at minimum. Furthermore, the catalogue and atlas contains data on 12 (4 %) dwarf novae of long cycle length or suspected dwarf novae for which only one outburst has been observed. Examples are WZ Sge and CI Gern. 6 (2%) recurrent novae or suspected recurrent novae are listed. Examples are T CrB and AS Psc. 6 (2%) X-ray novae are listed. Examples are V616 Mon and KY TrA. 6 (2%) symbiotic stars and symbiotic novae are listed. Examples are RT Ser and V352 Aql. 11 (4 %) Mira stars or suspected Mira stars, which at some time were believed to be novae, are listed. Examples are V607 Aql and V927 Sgr.

Astrophysics with Radioactive Isotopes
Author: Roland Diehl
Publisher: Springer
ISBN: 3319919296
Category : Science
Languages : en
Pages : 679
Book Description
Dealing with astrophysics derived from the radiation emitted by radioactive atomic nuclei, this book describes the different methods used to measure cosmic radio-isotopes. It demonstrates how this astronomical window has contributed to the understanding of the sources and the chemical evolution of cosmic gas. Reference materials and explanations are included for students in advanced stages of their education. Nuclear reactions in different sites across the universe lead to the production of stable and unstable nuclei. Their abundances can be measured through different methods, allowing to study the various nuclear processes taking place in cosmic environments. Nucleosynthesis is the cosmic formation of new nuclear species, starting from hydrogen and helium resulting from the big bang origins. Stars create and eject synthesized nuclei during their evolution and explosions. Incorporation of the new interstellar composition into next-generation stars characterises the compositional (chemical) evolution of cosmic gas in and between galaxies. Radioactive species have unique messages about how this occurs. Since the first Edition of this book published in 2011 with the title Astronomy with Radioactivities, long-awaited new direct observations of supernova radioactivity have been made and are now addressed in two updated chapters dealing with supernovae. In this second Edition, the advances of recent years beyond one-dimensional treatments of stellar structure and stellar explosions towards 3-dimensional models have been included, and led to significant re-writings in Chapters 3-5. The sections on the Solar System origins have been re-written to account for new insights into the evolution of giant molecular clouds. The chapter on diffuse radioactivities now also includes material measurements of radioactivities in the current solar system, and their interpretations for recent nucleosynthesis activity in our Galaxy. Significant new results on gamma-rays from positron annihilations have been accounted for in that chapter, and led to new links with nucleosynthesis sources as well as interstellar transport processes. A new chapter now provides a description of interstellar processes often called 'chemical evolution', thus linking the creation of new nuclei to their abundance observations in gas and stars. The experimental / instrumental chapters on nuclear reaction measurements, on gamma-ray telescopes, and pre-solar grain laboratories have been updated. Moreover, new windows of astronomy that have been opened up in recent years have been included in the discussions of the multi-messenger approach that broadens the basis for astrophysical insights.

Nuclear Physics of Stars
Author: Christian Iliadis
Publisher: John Wiley & Sons
ISBN: 3527336516
Category : Science
Languages : en
Pages : 675
Book Description
Most elements are synthesized, or "cooked", by thermonuclear reactions in stars. The newly formed elements are released into the interstellar medium during a star's lifetime, and are subsequently incorporated into a new generation of stars, into the planets that form around the stars, and into the life forms that originate on the planets. Moreover, the energy we depend on for life originates from nuclear reactions that occur at the center of the Sun. Synthesis of the elements and nuclear energy production in stars are the topics of nuclear astrophysics, which is the subject of this book. It presents nuclear structure and reactions, thermonuclear reaction rates, experimental nuclear methods, and nucleosynthesis in detail. These topics are discussed in a coherent way, enabling the reader to grasp their interconnections intuitively. The book serves both as a textbook for advanced undergraduate and graduate students, with worked examples and end-of-chapter excercises, but also as a reference book for use by researchers working in the field of nuclear astrophysics.

Observer's Guide to Variable Stars
Author: Martin Griffiths
Publisher: Springer
ISBN: 3030009041
Category : Science
Languages : en
Pages : 322
Book Description
This book contains everything you need to know about variable stars -- stars whose brightness varies noticeably over time. The study of variable stars has been a particularly popular area of research for amateurs for many years; the material contained herein serves as both an introduction to amateur astronomers and a useful reference source for seasoned variable star observers. With its thorough, non-mathematical descriptions of variable stars and tips for how to see them, this book enables novices and experts alike to set off into the field and observe a wide range of delightful sights. It strikes a balance between easily visible objects that can be seen in any telescope or binoculars, and variable stars that are a direct challenge to those with large aperture equipment or access to photometric tools and methods. After helping the observer differentiate between variable star types, the author goes on to explain the skills needed to operate a telescope and other equipment, as well as how to couple filters to a CCD camera or digital SLR camera in order to photometrically record these celestial objects. Further, the book includes an observational guide to 50 objects for study, with finder charts and data about light curves for ease of identification, along with the stars’ celestial coordinates, magnitudes, and other pertinent information.
