Available in PDF, EPUB and Kindle. Book excerpt: 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).

Download or read book A Reference Catalogue and Atlas of Galactic Novae written by Hilmar W. Duerbeck and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Extragalactic Novae written by Allen Wayne Shafter and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extragalactic Novae: A historical perspective takes the reader on a journey chronicling the study of a class of eruptive variable stars known as "Novae Stella", Latin for "New Stars". These mysterious transient objects, now referred to simply as novae, have been recognized since antiquity, suddenly appearing in the night sky before slowly fading back into obscurity. The book begins with a brief introduction to the early observations, including an overview of the role that novae played in the birth of extragalactic astronomy, and concludes with a discussion of how nova observations over the past century have contributed to our knowledge of close binary star populations in nearby galaxies. Along the way, the history of our understanding of the nova phenomena, in the Milky Way and beyond, is unveiled. In particular, the author describes how the enigmatic nova eruptions were finally realized to be the result of thermonuclear runaways on the surfaces of accreting white dwarf stars, how a controversial correlation between a nova's peak luminosity and its rate of decline (the MMRD relation) has been used in extragalactic distance determinations, and how recent observations have bolstered the case that novae may form a significant channel for the production of Type Ia supernovae. These topics, and more, are recounted by an observer who has spent the past 35 years studying these fascinating objects.

Book excerpt: Gerald North's complete practical guide and resource package instructs amateur astronomers in observing and monitoring variable stars and other objects of variable brightness. Descriptions of the objects are accompanied by explanations of the background astrophysics, providing readers with real insight into what they are observing at the telescope. The main instrumental requirements for observing and estimating the brightness of objects by visual means and by CCD photometry are detailed, and there is advice on the selection of equipment. The book contains a CD-ROM packed with resources, including hundreds of light-curves and over 600 printable finder charts. Containing extensive practical advice, this comprehensive guide is an invaluable resource for amateur astronomers of all levels, from novices to more advanced observers. Gerald North is a lifelong amateur astronomer. In addition to being a member of the British Astronomical Association since 1977, he is also the author of many books, including Advanced Amateur Astronomy (Cambridge, 1997) and Observing the Moon (Cambridge, 2000).
