Fast Spectral Variability from Cygnus X-1
Y. X. Wu, T. M. Belloni, L. Stella
We have developed an algorithm that, starting from the observed properties of the X-ray spectrum and fast variability of an X-ray binary allows the production of synthetic data rep…
Orbital Period and Outburst Luminosity of Transient Low Mass X-ray Binaries
Y. X. Wu, W. Yu, T. P. Li +2
In this paper we investigate the relation between the maximal luminosity of X-ray outburst and the orbital period in transient low mass X-ray binaries (or soft X-ray transients) ob…
On the Relation of Hard X-ray Peak Flux and Outburst Waiting Time in the Black Hole Transient GX 339-4
Y. X. Wu, W. Yu, Z. Yan +2
Aims. In this work we re-investigated the empirical relation between the hard X-ray peak flux and the outburst waiting time found previously in the black hole transient GX 339-4. W…
Timescale Resolved Spectroscopy of Cyg X-1
Y. X. Wu, T. P. Li, T. M. Belloni +2
We propose the timescale-resolved spectroscopy (TRS) as a new method to combine the timing and spectral study. TRS is based on the time domain power spectrum and reflects the varia…
X-Ray Spectral Variability in Initial Rise of XTE J1550-564
Y. X. Wu, C. Z. Liu, T. P. Li
X-ray variability of the microquasar XTE J1550-564 is studied with time domain techniques for the data from the RXTE/PCA observation in September 8, 1998. The 2--60 keV averaged sh…
