Suzaku studies of SFXT flare mechanisms
Abstract
To understand flare mechanisms of SFXTs, we analyzed Suzaku public data of AXJ161929-4945. The data covered a large flare with a rise time of about 500 sec and a duration of about 3 hours. Over a 1-40 keV band, the spectra were very similar between the flare and quiescence periods. The column density was not different between the two spectra by more than 10%. A narrow Fe-line were very clearly detected in the quiescence, but disappeared in the flare. These results suggest that the flare occured due to strong magnetic fields of the neutron star.
