Statistical Properties of SGR 1806-20 Bursts.
We present statistics of SGR 1806-20 bursts, combining 290 events detected with the Rossi X-Ray Timing Explorer/Proportional Counter Array, 111 events detected with the Burst and Transient Source Experiment, and 134 events detected with the International Cometary Explorer. We find that the fluence distribution of bursts observed with each instrument are well described by power laws with indices...
متن کاملSAX observations of SGR 1806 – 20
Your thesaurus codes are: missing; you have not inserted them ASTRONOMY AND ASTROPHYSICS Abstract. We have observed with the BeppoSAX satellite the quiescent counterpart of the Soft Gamma-ray Repeater SGR 1806–20. Observations performed in October 1998 and in March 1999 showed that this pulsar continued its long term spin-down trend at an average rate of ∼8 10 −11 s s −1 while its flux and spec...
متن کامل0 Timing Noise in SGR 1806 - 20
We have phase connected a sequence of Rossi X-ray Timing Explorer Proportional Counter Array observations of SGR 1806−20 covering 178 days. We find a simple secular spin-down model does not adequately fit the data. The period derivative varies gradually during the observations between 8.1 and 11.7 × 10−11 s s−1 (at its highest, ∼40% larger than the long term trend), while the average burst rate...
متن کاملThe Connection between W 31 , SGR 1806 - 20 , & LBV 1806 - 20 : Distance , Extinction , and Structure
We present new millimeter and infrared spectroscopic observations towards the radio nebula G10.0−0.3, which is powered by the wind of the Luminous Blue Variable star LBV 1806−20 also closely associated with the soft gamma-ray repeater SGR 1806−20, and believed to be located in the giant Galactic H ii complex W31. Based on observations of CO emission lines and NH3 absorption features from molecu...
متن کاملTiming Noise in SGR 1806-20.
We have phase-connected a sequence of Rossi X-Ray Timing Explorer Proportional Counter Array observations of SGR 1806-20 covering 178 days. We find that a simple secular spin-down model does not adequately fit the data. The period derivative varies gradually during the observations between 8.1x10-11 and 11.7x10-11 s s(-1) (at its highest, approximately 40% larger than the long-term trend), whil...
