I X - ray bursts in the low - mass X - ray binary 4 U 1636 – 53
Two flares with a duration of several hours are reported for the low-mass X-ray binary 4U 1636–53. The characteristics of these flares (i.e., decay time scales, spectral softening, fluences) are very similar to the very long type-I X-ray bursts recently found in several other low-mass X-ray binaries, suggesting that the flares in 4U 1636–53 are also very long type-I X-ray bursts. This would mak...
متن کاملRelativistic Iron Line Emission from the Neutron Star Low-mass X-ray Binary 4u 1636-536
We present an analysis of XMM-Newton and RXTE data from three observations of the neutron star LMXB 4U 1636-536. The X-ray spectra show clear evidence of a broad, asymmetric iron emission line extending over the energy range 4–9 keV. The line profile is consistent with relativistically broadened Fe K-α emission from the inner accretion disk. The Fe K-α line in 4U 1636-536 is considerably broade...

متن کاملThe reflection spectrum of the low - mass X - ray binary 4 U 1636 − 53
We present 3−79 keV NuSTAR observations of the neutron star low-mass X-ray binary 4U 1636−53 in the soft, transitional and hard state. The spectra display a broad emission line at 5−10 keV. We applied several models to fit this line: A gaussian line, a relativistically broadened emission line model, kyrline, and two models including relativistically smeared and ionized reflection off the accret...
