A temporal scale to track the spectral transitions in low-mass X-ray binaries

The results of a temporal analysis observations for sample nine low-mass X-ray binaries (LMXBs) are presented. Of these sources, five host neutron star (NS) primary (4U1608-52, Aql X-1, 4U1705-44, GX17+2 and Cyg X-2), four black hole (BH) (GX339-4, XTE J1859+226, H1743-322 MAXI J1659-152). NS group includes three Atolls two Z-type sources. We utilized archival Proportional Counter Array (PCA)/RXTE data to construct high-resolution lightcurves. A wavelet transform the lightcurves is deployed extract minimal time scale (MTS) associated with spectral state MTS, together fractional root-mean-square (RMS) hardness ratios, used RMS-MTS hardness-MTS diagrams that enable direct comparison evolution transitions in target Observations high RMS cluster broad region occupied jointly by BH For low exhibit large MTS whereas sources small MTS. This new feature raises possibility discriminating between types Moreover, plane, sole occupiers low-hardness small-MTS domain thus potentially signaling unique property distinguishing hosts LMXBs.
