Download or read book The Astrophysics of Emission Line Stars written by Tomokazu Kogure and published by Springer Science & Business Media. This book was released on 2010-05-05 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emission line stars are attractive to many people because of their spectacular phenomena and their amazing varieties and variability. This book offers general information on emission line stars, starting from a brief introduction to stellar astrophysics and then moving to a broad overview of emission line stars including early and late type stars as well as pre-main sequence stars.
Download or read book B e Stars written by Anne Marie Hubert and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of having a meeting came to the Editors when working on several aspects of galactic Be and B[e] stars. They found that a general summary of the properties of B[e] stars was missing, so that the organiza tion of a first meeting on these objects appeared as very useful. B[e] stars have hydrogen line emission and forbidden [Fe 11] and [0 I] emission lines in their spectra; they are also characterized by a strong IR excess due to circumstellar dust. Having a large amount of extinction in the UV and the visual they have been less frequently observed than other emission line objects. Although about one hundred galactic objects have been classified as B[e], only fif teen or so have been studied in some detail. Besides this, the evolutionary status of these objects is rat her controversial, are they pre-main sequence or stars on the way to become nUclei of planetary nebulae? Other difficult problems appear when considering the relations of these stars with other similar groups, like Herbig AeBe stars, Be, luminous blue variables and the superluminous B[e] stars observed in the Magellanic Clouds. The conference seems timely since large surveys like DENIS and 2Mass, plus new space and new instruments for the micron, millimeter and cen timeter wavelength region will result in the discovery of more stars of this group.
Download or read book The Early Type Stars written by A.B. Underhill and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: At this time when astronomers are being surprised by the discovery of objects which emit a fabulously large amount of energy, that is the quasi-stellar radio sources and the quasi-stellar galaxies, and when by the means of space vehicles X rays, gamma rays and cosmic rays are being observed to come from the depths of interstellar space, one may ask why write a book about stars. Stars seem to be almost incidental when one looks at the universe in terms of exceedingly great energies. Nevertheless, stars exist. They are accessible to study and they have not yet revealed all their secrets. This is enough to arouse interest and to cause one to try to find answers to the questions which arise. The early type stars are particularly interesting because they are spendthrift stars pouring out their energy at a great rate. But their brilliance is also their undoing. They must evolve rather quickly, on an astrophysical scale. Thus by studying these stars we are studying a population in change. The implications from the local and from the cosmological viewpoint are important if one wishes to understand the details of stellar evolution and of galactic structure. Perhaps one of the simplest reasons for writing a book about the early type stars is to see if some of the conundrums pre sented by the spectra of these stars can be unravelled when all the available infor mation is brought together.

Download or read book The Stars written by Evry L. Schatzman and published by Springer Science & Business Media. This book was released on 1993-04-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following an introductory chapter on stellar fundamentals, the story begins of the lives and deaths of the stars. The authors take us on a journey from the sun, a comparatively young star, to supernovae - manifestations of dramatic death. On the way, the reader, advanced undergraduate or beginning postgraduate, is presented with such topics as stellar evolution, the hydrodynamics of stellar interiors, variability, and solar and stellar activity. This comprehensive but rigorous text, building on the theoretical and observational advances of recent years - for instance, astrophysical theory in the light of Supernova 1987A - is required reading for all serious students of astronomy.
Download or read book Highlights of Astronomy written by C. de Jager and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 786 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the same pattern as the XIII th General Assembly of the International Astronom ical Union the present Volume of the Highlights in Astronomy contains the texts of the invited discourses given at the XIVth General Assembly held in Brighton, England, August 1970. It contains further the papers and discussion remarks presented at the six joint discussions, as well as the invited papers given at the special session on the Moon. In addition this Volume contains the papers given at the joint meeting of Commissions 24, 27, 30, 33 and 37 on RR Lyrae Stars. It goes without saying that the nearly hundred papers printed in this Volume represent only a minor part of all matter dealt with at the XIVth General Assembly of the Union; the many important discussions that took place in a few hundred commission meetings are not included. For short abstracts and reviews of these the reader is referred to Transactions of the International Astronomical Union XIVB. I wish to thank those who contributed to this Volume for the speed in submitting the manuscripts of their papers. This, together with the efficiency of the Publishers allowed for a rapid publication.

This book was released on 2013-06-29 with total page 1592 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Astronomy and Astrophysics Abstracts" appearing twice a year has become oneof the fundamental publications in the fields of astronomy, astrophysics andneighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. The abstrats are classified under more than a hundred subject categories, thus permitting a quick survey of the whole extended material. The AAA is a valuable and important publication for all students and scientists working in the fields of astronomy and related sciences. As such it represents a necessary ingredient of any astronomical library all over the world.

Download or read book Extended Atmospheres and Circumstellar Matter in Spectroscopic Binary Systems written by A.H. Batten and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposal to organize a Symposium on circumstellar matter and extended atmo spheres in binary systems was first made by the Dominion Astrophysical Observatory to the Executive Committee of the International Astronomical Union in the summer of 1969. It received the support of the presidents of Commissions 29 (Stellar Spectra), 30 (Radial Velocities), 36 (Stellar Atmospheres), and 42 (Photometric Double Stars). Approval in principle was given by the Executive Committee almost immediately, and the Committee further suggested that the Symposium be officially designated the Struve Memorial Symposium. Final approval was given at the time of the 1970 General Assembly of the Union. when the dates of the Symposium were set for August or September, 1972. The Organizing Committee set up consisted of K. O. Wright (Chairman), A. H. Batten, K. -H. B6hm, A. A. Boyarchuk, G. Larsson-Leander, and M. Plavec. In addition, J. Sahade and F. B. Wood acted as advisory members. Local organization was entrusted to a committee consisting of A. H. Batten, E. K. Lee, and C. D. Scarfe. The final dates selected were September 6-12, 1972, and the Sym posium was held at the Island Hall Hotel, Parksville, B. C. , on Vancouver Island some 90 miles from Victoria. The Organizing Committee attempted to arrange a Symposium of the type in which no contributed papers would be presented and discussion would range as widely as possible over the field covered by the six invited review papers.
