Burst Observations from the Two Neighboring Magnetars SGR 1806-20 and XTE J1810-197

Alaa I. Ibrahim



XTE J1810-197 is a newly discovered magnetar with a new flavor of being transient (Ibrahim et al. 2004). Monitoring observations revealed that the source emitted a few X-ray bursts that appear to show different properties than most SGR bursts (Woods et al. 2005). We confront these bursts with those from SGR sources, especially SGR 1806-20, and discuss the implications of the results to a number of open questions on magnetars including whether SGR and AXP bursts are intrinsically different and the presence of spectral line feature in some magnetar bursts.
