Abstract
We have developed a theoretical model for the X-ray emission from magnetars that takes into account the physical processes in their atmospheres and magnetospheres. We present the results of our analyses of the X-ray spectra of a number of Anomalous X-ray Pulsars using this model. In particular we show how our study leads to the measurement of the surface magnetic fields of the neutron stars and of the sizes of the emitting regions and helps constrain the origin and energetics of the outbursts in transient sources.
