Vistas in Astronomy, Volume 14: Astrometry - Theoretical Astrophysics – Instrumentation – Spectroscopy – Galactic Structure – Galaxies focuses on the methods, processes, and technologies used in astronomy. The selection first discusses the calculations of eclipse and lunar features. The method of computation, symbols that are used, and limit of the shadow path are explained. The book also looks at the spectral classification through seven-color photometry. The effects of chemical composition and interstellar absorption; pseudo-continua of dwarf stars; introduction of linear combinations of color indices; and variable and emission-line stars are discussed. The book also scrutinizes element abundance in O- and early B-stars. The method of fine analysis, observations, and fine analyses of normal and peculiar stars are explained. The book also examines the spiral structure and kinematics of the galaxy from a study of the H II regions. The study of the Doppler-Fizeau effect of the ionized interstellar hydrogen; extension of interference methods to the study of the structure of extragalactic nebulae; and structure and dynamics of barred spiral galaxies are discussed. The selection is a valuable source of information for readers interested in astronomy.
