X-ray Timing beyond the Rossi X-ray Timing Explorer
With its ability to look at bright galactic X-ray sources with sub-millisecond time resolution, the Rossi X-ray Timing Explorer (RXTE) discovered that the X-ray emission from accreting compact stars shows quasi-periodic oscillations on the dynamical timescales of the strong field region. RXTE showed also that waveform fitting of the oscillations resulting from hot spots at the surface of rapidl...
متن کاملThe Rossi X-Ray Timing Explorer
RXTE has been operating for nearly 2 years and is planning the third. The spacecraft performance has been good and the three instruments are operating well. Observations have been made of the range of targets suitable for RXTE, including such different objects as accreting neutron stars and black holes, stellar flares, and supernova remnants. The goals of studying high time resolution and broad...
متن کاملThermonuclear (type-i) X-ray Bursts Observed by the Rossi X-ray Timing Explorer
We have assembled a sample of 1187 thermonuclear (type-I) X-ray bursts from observations of 48 accreting neutron stars by the Rossi X-ray Timing Explorer, spanning more than ten years. The sample contains examples of two of the three theoretical ignition regimes (confirmed via comparisons with numerical models) and likely examples of the third. We present a detailed analysis of the variation of...
متن کاملMagnetic Fields of Accreting X–Ray Pulsars with the Rossi X–Ray Timing Explorer
Using a consistent set of models, we parameterized the X-ray spectra of all accreting pulsars in the Rossi X-ray Timing Explorer database which exhibit Cyclotron Resonance Scattering Features (CRSFs, or cyclotron lines). These sources in our sample are Her X-1, 4U 0115+63, Cen X-3, 4U 1626-67, XTE J1946-274, Vela X-1, 4U 1907+09, 4U 1538-52, GX 301-2, and 4U 0352+309 (X Per). We searched for co...
متن کاملAbsolute Timing of the Crab Pulsar with the Rossi X-ray Timing Explorer
We have monitored the phase of the main X-ray pulse of the Crab pulsar with the Rossi X-Ray Timing Explorer (RXTE) for almost 8 years, since the start of the mission in 1996 January. The absolute time of RXTE’s clock is sufficiently accurate to allow this phase to be compared directly with the radio profile. Our monitoring observations of the pulsar took place bi-weekly (during the periods when...
