Vistas in Astronomy is a periodical compilation of different studies submitted by experts in the fields of astronomy, astrophysics, photometry, celestial mechanics, and nuclear cosmology. The papers are published after thorough evaluation by the editors. The following volume includes papers about papers in astronomy such as: • Astronomy, the People, and the Governments by Jean Claude-Pecker and Gisele Ringeard • Computer Simulations of Star Cluster Dynamics by Sveere J. Arseth • Velocity Fields in Stellar Atmospheres and the Concept of Microturbulence by Gordon Worrall and Alistair B. Wilson • Image Tubes in Astronomy by J.D. McGee • High Speed Photometry by R. Edward Nather The text chiefly appeals to astronomers and astrophysicists, especially those who wish to know the innovations, discoveries, and practices in the field of astronomy.
Focussing on the formulation of mathematical models for the light curves of eclipsing binary stars, and on the algorithms for generating such models, this book provides astronomers, both amateur and professional, with a guide for - specifying an astrophysical model for a set of observations - selecting an algorithm to determine the parameters of the model - estimating the errors of the parameters. It is written for readers with knowledge of basic calculus and linear algebra; appendices cover mathematical details on such matters as optimisation, co-ordinate systems, and specific models. While emphasising the physical and mathematical framework, the discussion remains close to the problems of actual implementation. The book concludes with chapters on specific models and approaches and the authors'views on the structure of future light-curve programs.
A reference for astronomers and historians on astronomical spectroscopy, from the discovery of spectral lines through to the year 2000.
Founded in 1911, the AAVSO boasts over 1200 members and observers and is the world's largest non-profit organization dedicated to variable star observation. This timely book marks the AAVSO's centennial year, presenting an authoritative and accurate history of this important association. Writing in an engaging and accessible style, the authors move chronologically through five eras of the AAVSO, discussing the evolution of its structure and purpose. Throughout the text, the main focus is on the thousands of individuals whose contributions have made the AAVSO's progress possible. Describing a century of interaction between amateur and professional astronomers, the authors celebrate the collaborative relationships that have existed over the years. As the definitive history of the first hundred years of the AAVSO, this text has broad appeal and will be of interest to amateur and professional astronomers, as well as historians and sociologists of science in general.
