Transient Magnetars |

Abstract |
The results obtained through the study of the transient phenomena displayed by Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters over more than 10 orders of magnitudes of time-scale variability (from fraction of milli-seconds up to years) will be shown and discussed. Among others are: the discovery of rapid QPOs in the giant flares of SGR1806-20 and SGR1900+14, the study of intermediate flares from SGR1900+14, and the detection of long-duration outbursts from transient Anomalous X-ray Pulsars (XTE J1810−197, CXO J164710.2−455216 and 1E1547.0-5408) monitored through multi-wavelength observations. Information related to the neutron star and magnetosphere structure, the emitting processes, and the confined fireball properties have been inferred and will be discussed on the light of the theoretical model(s). |
