Spectral States of Xte J1701 – 462: Link between Z and Atoll Sources
We have analyzed 866 Rossi X-ray Timing Explorer observations of the 2006–2007 outburst of the accreting neutron star XTE J1701−462, during which the source evolves from super-Eddington luminosities to quiescence. The X-ray color evolution first resembles the Cyg X-2 subgroup of Z sources, with frequent excursions on the horizontal and normal branches (HB/NB). The source then decays and evolves...
متن کاملType I X-ray Bursts from the Neutron-star Transient Xte J1701-462
The neutron-star X-ray transient XTE J1701-462 was observed for ∼3 Ms with RXTE during its 2006-2007 outburst. Here we report on the discovery of three type-I X-ray bursts from XTE J1701462. They occurred as the source was in transition from the typical Z-source behavior to the typical atoll-source behavior, at ∼ 10% of the Eddington luminosity. The first burst was detected in the Z-source flar...
متن کاملRxte Observations of the First Transient Z Source Xte J1701–462: Shedding New Light on Mass Accretion in Luminous Neutron Star X-ray Binaries
We report on the first ten weeks of Rossi X-ray Timing Explorer observations of the X-ray transient XTE J1701–462. Large count rate variations were accompanied by changes in the source’s spectral and variability properties. Based on comparisons with other sources we conclude that XTE J1701–462 had all the characteristics of the neutron star Z sources, i.e., the class of the brightest persistent...
متن کاملTime-lag cross-correlations in collective phenomena
We study long-range magnitude cross-correlations in collective modes of real-world data from finance, physiology, and genomics using time-lag random matrix theory. We find longrange magnitude cross-correlations i) in time series of price fluctuations, ii) in physiological time series, both healthy and pathological, indicating scale-invariant interactions between different physiological time ser...
متن کاملThe Connection Between Spectral Evolution and GRB Lag
The observed delay in the arrival times between high and low energy photons in gamma-ray bursts (GRBs) has been shown by Norris et al. to be correlated to the absolute luminosity of a GRB. Despite the apparent importance of this spectral lag, there has yet to be a full explanation of its origin. We put forth that the lag is directly due to the evolution of the GRB spectra. In particular, as the...
