Rapid Spindown of Sgr 1900+14 following Its Superburst
نویسنده
چکیده
SGR 1900+14 had a brief episode of exceedingly rapid spindown immediately following its 1998 Aug. 27 superburst. On a timescale of hours, it increased its period by a part in 10. The corresponding Ṗ ∼ 10 is orders of magnitude higher than the typical quiescent rate of Ṗ ∼ 6×10.

The Effects of Burst Activity on Soft Gamma Repeater Pulse Properties and Persistent Emission
Soft Gamma Repeaters (SGRs) undergo changes in their pulse properties and persistent emission during episodes of intense burst activity. SGR 1900+14 has undergone large flux increases following recent burst activity. Both SGR 1900+14 and SGR 1806−20 have shown significant changes in their pulse profile and spindown rates during the last several years. The pulse profile changes are linked with t...

We consider the physical implications of the rapid spindown of Soft Gamma Repeater 1900+14 reported by Woods et al. During an 80 day interval between June 1998 and the large outburst on August 27 1998, the mean spin-down rate increased by a factor 2.3, resulting in a positive period offset of ∆P/P = 1 × 10−4. A radiation-hydrodynamical outflow associated with the August 27th event could impart ...
متن کاملTitle The radio afterglow from the giant flare of SGR 1900+14: The same mechanism as afterglows from classic gamma-ray bursts?
A radio afterglow was detected following the 1998 August 27 giant flare from the soft gamma repeater (SGR) 1900 14. Its short-lived behavior is quite different from the radio nebula of SGR 1806 20, but very similar to radio afterglows from classic gamma-ray bursts (GRBs). Motivated by this, we attempt to explain it with the external shock model as invoked in the standard theory of GRB afterglow...

متن کاملOn the Nature of Soft Gamma-ray Repeaters
Soft gamma-ray repeaters (SGRs) and Anomalous X-ray pulsars (AXPs) are generally accepted to be magnetars. Recently, Zhang, Xu & Qiao (2000, ApJ, 545, L127) proposed an alternative viewpoint about the nature of the SGRs (and AXPs). In this picture, SGR bursts are attributed to the impacts of some comet-like objects with the central bare strange star. Here I briefly review this model, and confro...
