Informationen zum Autor John H. Thomas is Professor of Mechanical and Aerospace Sciences! and Astronomy! at the University of Rochester. He has been the Chair of the Solar Physics Division of the American Astronomical Society! and was a Scientific Editor of the Astrophysical Journal for ten years. Nigel O. Weiss is Emeritus Professor of Mathematical Astrophysics at the University of Cambridge. He is a former President of the Royal Astronomical Society! which awarded him a Gold Medal in 2007. Klappentext The past two decades have seen remarkable advances in observations of sunspots and their magnetic fields, in imaging of spots and fields in distant stars and in associated theoretical models and numerical simulations. This book provides a comprehensive combined account of the properties of sunspots and starspots. It covers both observations and theory, and describes the intricate fine structure of a sunspot's magnetic field and the prevalence of polar spots on stars. The book includes a substantial historical introduction and treats solar and stellar magnetic activity, dynamo models of magnetic cycles, and the influence of solar variability on the Earth's magnetosphere and climate. This volume is a valuable reference for graduate students and specialists in solar and stellar physics, astronomers, geophysicists, space physicists and experts in fluid dynamics and plasma physics.
