Type 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 کاملXTE J2123–058: A New Neutron Star X-Ray Transient
We report on optical and RXTE observations of a new high-latitude bursting X-ray transient, XTE J2123–058. We identified the optical counterpart and discovered a 5.9573 ± 0.0016 hr periodic optical modulation, which was subsequently shown to be the same as the spectroscopic orbital period. From the absence of orbital X-ray modulation and the presence of partial optical eclipses the binary incli...
متن کاملDiscovery of 1122 Hz X-ray Burst Oscillations from the Neutron-star X-ray Transient Xte J1739-285
We report the discovery of oscillations at 1122 ± 0.3 Hz in an X-ray burst from the X-ray transient XTE J1739-285. The signal has a peak Leahy power of 42.8 and, after consideration of the number of trials, has a chance probability of occurrence of 4×10 −5 , equivalent to a 4.2σ detection. The oscillation frequency suggests that XTE J1739-285 contains the fastest rotating neutron star yet found...
متن کاملThe Low Quiescent X-ray Luminosity of the Neutron Star Transient Xte J2123–058
We report on the first X-ray observations of the neutron star soft X-ray transient (SXT) XTE J2123–058 in quiescence, made by the Chandra X-ray Observatory and BeppoSAX, as well as contemporaneous optical observations. In 2002, the Chandra spectrum of XTE J2123–058 is consistent with a power-law model, or the combination of a blackbody plus a power-law, but it is not well-described by a pure bl...
متن کاملLong Type I X-ray Bursts and Neutron Star Interior Physics
Superbursts are very energetic Type I X-ray bursts discovered in recent years by long term monitoring of Xray bursters, believed to be due to unstable ignition of carbon in the deep ocean of the neutron star. A number of intermediate duration bursts have also been observed, probably associated with ignition of a thick helium layer. We investigate the sensitivity of these long X-ray bursts to th...
