Provides researchers in the field with a comprehensive and up-to-date account of current research on astrophysical jets. An important feature of the book is that it combines discussions of jets on stellar as well as galactic scales. There are ten chapters, authored by fourteen active researchers, all of whom are experts on their chosen topics. Recent hydrodynamic simulations of jets are included and reference to observations of actual jets is made where appropriate. The book has been coherently edited to provide a cohesive account of this field of study. It will be an important textbook for graduate students, and a valuable reference source for researchers in high energy astrophysics. It will also be of interest to plasma physicists and space scientists.
