Book Description
Door middel van gedetailleerde studies aan de infrarood gegevens van oude sterren is het stof rond koolstofrijke Rode Reuzen onderzocht. De aanwezigheid van een aantal nieuwe materialen in de ruimte is ontdekt. Daarmee is een completer beeld van de samenstelling, locatie en het lot van het stof rond koolstofrijke oude sterren verkregen. Daarmee verschaffen de in dit proefschrift gepresenteerde studies een rijker inzicht in het stof rond oude sterren en deze sterren zelf.

Book Description
The underlying astrophysical mechanisms of the objects known as asymptotic giant branch stars - the structures that occur during the dramatic period prior to a star's death - is the main theme of this text. Over the past three decades, asymptotic giant branch stars have become a topic of their own, and the contributions to this volume all focus on these entities themselves, rather than their connections to other fields of astronomy. Among the many topics covered are new methods of high- quality infrared observation and the more detailed and realistic simulations made possible by increasingly fast computers. This collection should be useful to graduate students who work in the field, teachers who want to address the subject in their courses, and to astronomers from various backgrounds who are interested in the astrophysics of AGB stars.

Book Description
This book surveys our understanding of stars which change in brightness because they pulsate. Pulsating variable stars are keys to distance scales inside and beyond the Milky Way galaxy. They test our understanding not only of stellar pulsation theory but also of stellar structure and evolution theory. Moreover, pulsating stars are important probes of the formation and evolution of our own and neighboring galaxies. Our understanding of pulsating stars has greatly increased in recent years as large-scale surveys of pulsating stars in the Milky Way and other Local Group galaxies have provided a wealth of new observations and as space-based instruments have studied particular pulsating stars in unprecedented detail.

Book Description
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.

Book Description
Outstanding progress in near-infrared detection technology and in real-time image processing has led astronomers to start undertaking all-sky surveys in the 1--2 mum range (project DENIS in Europe and 2MASS in the U.S.A.), surveys which will have a considerable impact in various areas of astronomy. This book gathers the contributions of more than 80 specialists involved in fields of interest as different as low mass stars, late stages of stellar evolution, star formation, stellar populations of the Galaxy and the Magellanic Clouds, the local structure of the Universe, and observational cosmology. It describes the impact on these fields of the exhaustive data bases and catalogs of stars and galaxies that these surveys will provide. The considerable interest of these documents for the future of infrared space and ground-based projects and the complementarity with other currently ongoing or planned surveys in other spectral ranges are emphasized.

Book Description
Analysis of the IRAS low resolution spectra show that the 8-22 micron spectral range show a variety of emission features. The strongest features in spectra of M stars are the 10 and 18 micron silicate emission features. In addition a three-component feature with peaks at 10, 11 and 13.1 micron and a weak, broad 9-15 micron feature is present in many M variable stars. Most carbon stars show the 11.2 micron SiC emission feature as well as, in some cases, an unidentified 8-9 micron emission feature. The MS, S and SC stars show a range of emission features whose peaks range from 10 to 11.2 micron. The excess emission above the underlying photospheric continuum in the 8-22 micron region for S Mira variables shows a sharp increase for period greater than about 370 days.
