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 Little Book of Stars written by James B. Kaler and published by Springer Science & Business Media. This book was released on 2013-11-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Little Book of Stars answers, in the clearest language, the questions anyone might have about our heavenly canopy. How are stars born? How do they die? Why do they shine? How long do they shine? Is our star, the Sun, dying? How can you tell time from the stars? Or navigate? What are the measures of stars? Can we ever travel to other stars? In this engagingly written and concise book, the second in the Little Book series, noted astronomer James B. Kaler shows us "the significance that the stars have had in human life, how we have used them to tell our stories, and how we use them to find who and where we are."
Download or read book Stars written by James B. Kaler and published by Times Books. This book was released on 1992 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this fascinating Journey to the farther reaches of space, astronomer James Kaler explores the nature of stars, describing their origins, varieties, distributions, compositions, and distinctive histories. He demonstrates that stars are the key to our comprehension of how the universe evolved--and that the birth, development, and death of stars is intimately associated with our own origins. From the earliest folklore to recent theories about dark matter, Stars chronicles the science of stellar astronomy, concluding with the evolution of high mass stars, whose spectacular deaths generate supernovae, pulsars, neutron stars, and enigmatic black holes. Elegantly written and illustrated, Stars is a compelling portrait of the cosmos as a vast engine of regeneration where stars are born, live, and die.

Available in PDF, EPUB and Kindle. Book excerpt: While there are guides to the visible sky, this is the first book to encompass the most important stars known in the universe at a level accessible to the layperson. The noted astronomer James Kaler takes us on a tour of the 100 most interesting stars, describing their characteristics and importance in words and vivid pictures. James B. Kaler is an internationally recognized expert on stars and their formation. A professor of astronomy at the University of Illinois, he is the author of "Stars and Their Spectra" (Cambridge), "Stars" (Freeman/Scientific American Library), "Cosmic Clouds" (Freeman/Scientific American Library), and numerous articles for popular and professional astronomy magazines.
Download or read book Magnetic Fields in O B and A Stars written by Swetlana Hubrig and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The last few decades have seen significant progress in our understanding of the occurrence of magnetic fields in stars with radiative envelopes, in particular in massive stars and in intermediate mass stars at early evolutionary stages. This book provides a comprehensive review of the most recent achievements in the measurements of stellar magnetic fields in O, B, and A stars. These include the archetypes of stellar magnetism, the chemically peculiar Ap and Bp stars, O- and early B-type stars with their magnetospheres, accreting Herbig Ae/Be stars, Wolf-Rayet stars, and high-mass X-ray binaries, among others. It provides an overview of the underlying physics for the interpretation of the data and identifies the requirements, both observational and theoretical, for improving our understanding of the origin of the magnetic fields in early-type stars. It aims to educate scientists working on stars, who are not yet experts in magnetic field studies, assuming that the reader is already familiar with basic terms and concepts of stellar astrophysics.
