Dynamo Problems in Astrophysics

This classic review presents some topics in hydromagnetic dynamo theory in the astrophysical context of large magnetic Reynolds number. An account is given of certain qualitative aspects of a turbulent dynamo operating through nonuniform rotation of a conducting medium subject to random motions with helicity. Such dynamos might be at work in planetary cores, stellar envelopes, galaxies and the gaseous accretion disks around X-ray sources.Ya.B. Zel'dovich A.A. Ruzmaikin
