Book excerpt: The Nebular Variables focuses on the nebular variables and their characteristics. Discussions are organized by type of nebular variable, namely, RW Aurigae stars, T Orionis stars, T Tauri stars, and peculiar nebular objects. Topics range from light variations of the stars to their spectroscopic and physical characteristics, spatial distribution, interaction with nebulosity, and evolutionary features. This volume is divided into four sections and consists of 25 chapters, the first of which provides general information on nebular variables, including their stellar associations and their classification into three distinct groups: RW Aurigae, T Orionis and T Tauri variables. These three groups of nebular variables are examined in more detail in the chapters that follow in terms of their light variations, spatial distribution, interaction with nebulosity, and spectroscopic, physical, and evolutionary characteristics. Visual and photoelectric light curves, mass loss determined spectroscopically, luminosities, and stellar radii are considered. The book also explores the possibility that some of the nebulae associated with certain nebular variables have evolved from a protoplanetary disc of material consisting of both gas and solid matter. Peculiar nebular variables such as the long period variable R Aquarii, Herbig-Haro objects, symbiotic variables, and infrared stars are analyzed as well. This book is written primarily for students and teachers of astronomy.

Available in PDF, EPUB and Kindle. Book excerpt: From September 5 until September 9, 1968, the IVth Colloquium on Variable Stars was held in Budapest, Hungary. The Colloquium was organized by a committee consisting of G.H. Herbig (President), A. Boyarchuk, M.W. Feast, D. McNamara, J.E. Merrill, D.J.K. O'Connell, V. Tsessevich, W. Wenzel. The local organization was placed in the hands of a Committee consist ing of members of the Konkoly Observatory, Budapest: L. Detre (Chairman), 1. Almar, Julia Balazs-Detre, K. Barlai, M. Ill, S. Kany6, M. Lovas and of J. Kovacs (Hungarian Academy of Sciences). The Colloquium was attended by about 90 scientists representing Argentina, Austria, Bulgaria, Canada, France, GDR, GFR, Hungary, Italy, The Netherlands, Poland, Roumania, South Africa, Sweden, United Kingdom, U.S.A., U.S.S.R. As chairmen acted at the sessions: M.W. Feast, G.H. Herbig, J. Sahade, A. Boyarchuk, W. Wenzel, F.B. Wood and L. Rosino. The contents of the present volume parallel closely the programme of the individual sessions of the Colloquium.

This book was released on 1990-06-30 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some 70 papers present the flare star problem from both a physical and evolutionary aspect, and represent an interaction between investigators working on flare stars in clusters and associations, and those working on the UV Ceti stars in solar vicinity. The variety of perspectives reveal a physical similarity among several non-stable phenomena, and suggest that the different manifestations of stellar activity result from the release of some unknown kind of energy in the outer layers of young stars. The papers deal not only with different aspects of flare stars, but also with such related objects as T Tauri stars, fluors, and Herbig-Haro objects.

Available in PDF, EPUB and Kindle. Book excerpt: Cataclysmic Variables (CVs) are well furnished laboratories in which one can investigate a number of important physical processes. These processes include: thermonuclear reactions, nebular physics, winds, mass accretion phenomena on compact objects, magnetohydrodynamics, plasmas, thermal and non thermal radiative processes, relativistic phenomena, dust forma tion, etc . . In the recent year the most exciting development in our opinion was that the small, cold and invisible secondary components of CV s were found to be the prime motors for the evolution of close binary systems, disclosing new scenarios for research. All branches of astronomy and as trophysics often take advantage of the new ideas brought by the study of CVs. It is for this reason, we believe, that meetings on CVs are important for most of the astronomical community. The idea of a Congress on CVs in Padova has been fluttering in the air for a few years. After all - we thought - a large part of the scientific heritage of Padova and Asiago Observatories is represented by the study of variable stars and, in particular, of CV s, as Prof. L. Rosino reminded us at the very beginning of the Congress. We finally chose Abano Terme as the site of the Conference, not merely because Abano is one of the most famous centers in Europe for mud therapy, and astronomers easily suffer from rheumatism, but also because we knew that a very hearty welcome from the Abano Municipality and touristic associations awaited us.

This book was released on 2012-12-06 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of holding a colloquium on Schmidt telescopes (techniques and science) originated from the observation that, in the last ten years and in spite of the remarkable developments and achievements in this field of astronomical research, there had been no specific opportunity for the experts to meet together, make the point on the state of the art, discuss and coordinate future plans. Therefore, Prof. L. Rosino, one of the pioneers in the use of wide-field telescopes, driven also by the wish of honouring the over four decades of activity of the Asiago Observatory, proposed to the Executive Committee of the International Astronomical Union to sponsor a colloquium on 'Astronomy with Schmidt type telescopes I to be held at Asiago at the end of the summer of 1983. Details about the composition of the Scientific Organizing Committee and the sponsoring organizations are given in Prof. Rosino's 'Welcome to the Participants • The granting of this proposal was the beginning of a ' number of headaches tor the members of the Local Organizing Committee, R. Barbon, F. Ciatti, P. Rafanelli and myself. If, organlzationwise, the colloquium was successful, this is truly due to the generous efforts of my colleagues of the SOC and to the efficient organization of the Linta Park, the hotel hosting the meeting.

Available in PDF, EPUB and Kindle. Book excerpt: Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.

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).
