Galactic Astronomy

This is a treatment of the phenomenology of galaxies. The text draws on observations of both our own galaxy, the Milky Way, and of external galaxies. It emphasizes the observational basis for current understanding of galactic astromony in the late '90s.

Klappentext
GALACTIC ASTRONOMY introduces all astronomical concepts necessary to understand the properties of galaxies, including coordinate systems, magnitudes and colors, the phenomenology of stars, the theory of stellar and chemical evolution, and the measurement of astronomical distances. 100 photos.

Zusammenfassung
Covers the phenomenology of external galaxies, star clusters in the Milky Way, the interstellar media of external galaxies, gas in the Milky Way, the structure and kinematics of the stellar components of the Milky Way, and the kinematics of external galaxies. This book is intended for professionals, as well as for students.
