The Complete Spectrum of the Neutron Star X- Ray Binary
We observed the neutron star (NS) ultra-compact X-ray binary 4U 0614+091 quasi-simultaneously in the radio band (Very Large Array), mid-infrared (IR)/IR (Spitzer/Multiband Imaging Photometer for Spitzer and Infrared Array Camera), near-IR/optical (Small and Moderate Aperture Research Telescope System), optical–UV (Swift/UV–Optical Telescope), soft and hard X-rays (Swift/X-ray Telescope and Ross...
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 کاملRelativistically broadened iron line in the SUZAKU observation of the neutron star X-ray binary 4U 1705-44
The X-ray spectra of accreting compact objects often exhibit discrete emission features associated with fluorescent emission in the accretion disk, the strongest of which is the Fe Kα fluorescence line at 6.4–6.97 keV. These reflection features are amongst the best tools in the study of the inner region of accretion flow around a compact object. Here we report on three SUZAKU observations of th...
متن کاملThe Uv Spectrum of the Ultra-compact X-ray Binary– 4u 1626-67
We have obtained Hubble Space Telescope/STIS low-resolution ultraviolet spectra of the Xray pulsar 4U1626-67 (=KZ TrA); 4U 1626-67 is unusual even among X-ray pulsars due to its ultra-short binary period (P=41.4 min) and remarkably low mass-function (≤ 1.3 × 10 M⊙). The far-UV spectrum was exposed for a total of 32ks and has sufficient signal-to-noise to reveal numerous broad emission and promi...
