Book Description
X-ray binaries are some of the most varied and perplexing systems known to astronomers. The compact object which accretes mass from its companion star may be a white dwarf, neutron star, or black hole, whereas the donor star can be a 'normal' star or a white dwarf. The various combinations differ widely in their behaviour, and this timely volume provides a unique reference of our knowledge to date of all of them.Fifteen specially written chapters by a team of the world's foremost researchers in the field explore all aspects of the X-ray binaries. They cover the X-ray, ultraviolet, optical and radio properties of these violent systems and address key issues such as: how were these systems formed, and what will be their fate; how can we understand X-ray bursts, and how the quasi-periodic oscillations; what is the connection between millisecond radio pulsars and low-mass X-ray binaries; and how does the magnetic field of a neutron star decay?This long awaited review provides graduate students and researchers with the standard reference on X-ray binaries for many years to come.

Book Description
X-ray astronomy, by necessity, involves the study of highly variable stars, nearly all of them in binary systems where one member is a compact object such as a neutron star or black hole. These systems allow us to probe physical effects in regions of extreme gravity, high temperatures, and intense magnetic fields that are characteristic of compact objects and are unattainable in laboratory experiments. By studying the brightness variations and eclipses using space-based X-ray telescopes, we can determine the binary system orbital parameters and characteristics of the mass transfer that powers these variations. This, in turn, allows us ultimately to understand better the evolution of these exotic binary systems. Here we describe two such studies carried out at NRL: the discovery of the orbit of a neutron star orbiting a hot supergiant star, and the surprising orbital period evolution observed in a lowmass X-ray binary.

X-ray Spectroscopy of Low-mass X-ray Binaries

Book Description
(Cont.) High-resolution X-ray studies of ISM absorption features can provide measurements of the relative abundances and ionization fractions of all the elements from carbon through iron. X- ray studies also probe the ISM on larger scales than is possible in the optical and ultraviolet wavebands. I present high-resolution spectroscopy of the oxygen K-shell ISM absorption edge in seven X-ray binaries using Chandra. The best-fit model consists of two absorption edges and five Gaussian absorption lines and can be explained by the recent theoretical calculations of K-shell absorption by neutral and ionized atomic oxygen. Significant oxygen features from dust or molecular components, suggested in previous studies, are not required by the Chandra spectra. These measurements also probe large-scale properties of the ISM, placing a limit on the velocity dispersion of the neutral lines of less than 200 km s-1 and constraining the interstellar ratio of O II/O I to approximately 0.1 and the ratio of O III/O I to less than 0.1.
