Short Description

Starting from the physical concepts of magnetohydrodynamics the authors adopt concepts, experiments and calculations for star formation and planetary evolution, the galactic dynamo and strong fields in astrophysics. New experimental results that impressively prove the validity of the powerful simulations and complex algorithms to modern astrophysics are provided for astrophysicists, geophysicists, researchers and students alike.

Magnetism is one of the most pervasive features of the Universe, with planets, stars and entire galaxies all having associated magnetic fields. All of these fields are generated by the motion of electrically conducting fluids, the so-called dynamo effect. The precise details of what drives the motion, and indeed what the fluid consists of, differ widely though. In this work the authors draw upon their expertise in geophysical and astrophysical MHD to explore some of these phenomena, and describe the similarities and differences between different magnetized objects. They also explain why magnetic fields are crucial in the formation of the stars, and discuss promising experiments currently being designed to study some of the relevant physics in the laboratory. This interdisciplinary approach makes the book appealing to a wide audience in physics, astrophysics and geophysics.

"Researchers and advanced students will greatly profit from this book."
Rainer Beck, Max-Planck-Institut für Radioastronomie, Bonn

"The authors do a good job of conveying the excitement of the subject and of bringing together much of the research of important topics, a welcome addition to the bookshelves."
The Observatory

"Ruediger and Hollerbach have brought together the significant research on this topic ... will be of interest to both the geophysicist and the astro-physicist, and perhaps the physicist or engineer ..."
E-STREAMS

"... does contain many deep insights and there is valuable material...that is not easily accessible elsewhere.."
Geophysical and Astrophysical Fluid Dynamics

"...a valuable book to have and study...an encyclopedic guide to some of the most interesting problems in astrophysics...should be savored over many sittings."
