About the author: John Binney is Emeritus Professor of Astronomy at the California Institute of Technology. He is an authority on galactic dynamics and the galactic disk, and his published works include: Galactic Astronomy, Dynamics of Galaxies, Galactic and Stellar Kinematics, Galactic Dynamics, and his masterpiece, The Galactic and Stellar Contacts.
About the book: Astronomers and astrophysicists have yet to see the combination of data and astronomical theory that will revolutionize their understanding of the galaxy. But, just as the advent of the 21st century will usher in a new age of astronomy, the old paradigm of galaxy formation and evolution will no longer suffice. The new light produced by a telescope capable of detecting photons from the ultraviolet to the infrared will open a new era in the field, and the new understanding of galactic phenomena that it brings will be more powerful than the understanding of the last century.
Synopsis: Astronomers and astrophysicists have yet to see the combination of data and astronomical theory that will revolutionize their understanding of the galaxy. But, just as the advent of the 21st century will usher in a new age of astronomy, the old paradigm of galaxy formation and evolution will no longer suffice.
This book is a must for students of astronomy and astrophysics, as well as for anyone with an interest in our galaxy or in galaxies in general. The stellar rotation curves of external galaxies are critical for determining the distance to a galaxy, and estimating the total mass of a galaxy. Astronomers understand that, in the absence of dark matter, stars alone cannot explain the observed rotation curves of most galaxies. The situation is further confused by the many cases of galaxies in which the stellar rotation curve rises sharply at some radius, but flattens out at larger radius, indicating that there is not enough mass in stars to generate a flat rotation curve. Binney and Merrifield's discussion of the dark matter problem is extensive and very informative.
Finally, this book discusses the phenomenology of our own Milky Way. As suggested above, the Milky Way is a spiral galaxy which is often an excellent laboratory for theories of galactic dynamics. By understanding the physics of the Milky Way, astronomers learn about galactic dynamics at large, and the development of ideas about the large-scale structure of the universe.
This book is aimed to be a basic reference book for the study of the Galaxy, and its readers should be able to understand the core science behind the book. If you are already familiar with the Galaxy, you can skim through the book in a couple of hours. If you haven't read any astronomy book and are interested in this subject, you can read the whole book by filling in the gaps. The book is designed to be used as a reference work, and I have provided a brief overview of the contents in the beginning of each chapter. Readers who want to go beyond what is given in the book can consider reading the original papers or consulting other books. 827ec27edc
