Description and Table of Contents
Description
This monograph presents the first comprehensive and detailed explanation for the planetary rings of Saturn, Uranus, Jupiter, and Neptune, exploring their striking, recently discovered structures such as narrow ringlets, spiral waves, and chain of vortices. This authoritative book is written in an accessible and engrossing style and is supplemented with an array of informative illustrations that will be of interest to professional and amateur astronomers, physicists, and students.
