Cool Stars with Excesses of Heavy Elements : Proceedings of the Strasbourg Observatory Colloquium Held at Strasbourg, France, July 3–6, 1984

**`**This comprehensive review of red giant stars with excesses of heavy metals succeeds in conveying not only the wealth of observational data now available on the characteristics of cool stars but also the extraordinary progress of the last 65 years in understanding the complex process of stellar evolution. The book serves as an important milestone on the way to a more complete understanding of the evolution of stars.**'****Science, 232 (1986)** Front Matter....Pages i-xvi Front Matter....Pages 1-1 Taxonomy of Late-Type Giants....Pages 3-14 Spectral Classification and the Relations Between Peculiar Giants....Pages 15-18 The Infrared Spectra of Red Variables: II The SC and CS Stars....Pages 19-23 Spectrophotometry Characteristics of Barium Stars....Pages 25-29 Identification of Photographic Infrared Spectral Region in Carbon Stars....Pages 31-35 Peculiar Cool Stars in Planetary Nebulae - The Spectrum of FG Sge....Pages 37-41 The Discovery and Frequency of Barium Stars....Pages 43-46 The IUE Low-Dispersion Spectra Reference Atlas....Pages 47-52 Ultraviolet Spectra of N, R, and S Stars....Pages 53-57 Front Matter....Pages 59-59 Photometric Properties of Peculiar Red Giants....Pages 61-85 Absolute Spectrophotometry of F-, G-, K-, and M-Type Stars....Pages 87-91 Calibrations of Photometric Indices on New Temperature Scales and Problem of Spectral Classification in M and C Stars....Pages 93-97 A New Photometric System for Monitoring Carbon Star Variability....Pages 99-104 Some Properties of S Mira Variables....Pages 105-109 Front Matter....Pages 111-111 The Distribution and Motions of Peculiar Red Giants....Pages 113-133 The Catalogue of Stellar Groups.

Keenan when he visited the Centre de Donnees Stellaires, in September 1982. Dr. A. Florsch, Director of the Strasbourg Observatory, kindly accepted to field it at Strasbourg. The scientific organization of the colloquium was in charge of a Committee chaired by Prof. P.C. Keenan and composed by M. Feast, A. Florsch, B. Gustafsson, D. Harmer, M. Jaschek (secretary), R. McClure, A. Maeder, W. Straizys and T. Tsuji. The members of the Committee helped to translate the idea into a very successful meeting. It should be added that this colloquium was the first meeting devoted to late-type peculiar stars. The program was organized by sessions devoted to the following topics : taxonomy, photometric properties, distribution and space motions, chemical com position, model atmosphere, binary systems and evolutionary tracks. Each session started with a review paper, followed by contributed papers presented as posters. The different sessions were chaired by W. Bidelman, R. Cayrel, Ch. Cowley, A. Heck, H.R. Johnson, J.P. Kaufmann and T. Tsuji, who did an excellent job. The President of the "Louis Pasteur University of Strasbourg", Prof. H. Duranton, welcomed the participants to the University where the sessions were held; Dr. A. Florsch welcomed the participation on be.balf of the French astrono mical community and Prof. P. Keenan spoke on behalf on the Scientific Organizing Committee ` This comprehensive review of red giant stars with excesses of heavy metals succeeds in conveying not only the wealth of observational data now available on the characteristics of cool stars but also the extraordinary progress of the last 65 years in understanding the complex process of stellar evolution. The book serves as an important milestone on the way to a more complete understanding of the evolution of stars.
