List of abstracts
Roberto Turolla
(Padova University & INFN)
Lecture 1 - Soft gamma-repeaters and Anomalous X-ray pulsars (SGRs & AXPs): the observational manifestations of magnetars
The observational properties of "magnetar sources" are reviewed. This will cover both the persistent emission at different wavelenghts and bursts & flares from SGRs and AXPs. Observational evidences in favor of the magnetar scenario are discussed.
Lecture 2 - Persistent emission from magnetar sources
The current picture for the persistent X-ray emission of magnetars is presented. Starting from the "twisted magnetosphere" model it is shown how the observed X-ray spectrum can be reproduced and how the comparison of models with data can probe the structure of the star magnetosphere.
Lecture 3 - Transient magnetars, bursts & giant flares
Emission from magnetars is variable on different timescales, from less than a second for the bursts, to several months for the outbursts which characterize transient sources. The current modeling and the physical mechanisms responsible for these phaenomena are reviewed.
