Abstract

Stellar magnetic fields govern key aspects of the evolution of a young star, from controlling accretion to regulating the angular momentum evolution of the system. Spectro-polarimetric studies of T Tauri stars have revealed a surprising range of magnetic field topologies. Meanwhile multi-wavelength campaigns have probed T Tauri star systems from stellar photosphere to inner disk, allowing us to study magnetospheric accretion in unprecedented detail. We review recent results and discuss their implications for understanding the evolution of young stars (© 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
