Spectral Comparisons of Neutron Star Low-Mass X-Ray Binariesudwith Black Hole X-Ray Binaries

摘要

The study of high-resolution X-ray spectra of neutron star low-mass X-ray binaries (LMXBs) allows the investigation of the innermost parts of the accretion disk and immediate surroundings of the compact object. The weak magnetic eld of old neutron stars present in such systems allows theudaccretion disk to approach very close to the compact object, like in black hole X-ray binaries. Using data from X-ray satellites such as XMM-Newton, RXTE, and BeppoSAX, I studied the reection component in two neutron star LMXBs:udMXB 1728-34 and 4U 1735-44. I showed that the iron line at 6:4
