Full Description: "X-ray binaries are stellar systems that combine one normal star (like our sun) and a smaller star, such as a white dwarf, a neutron star, or a black hole.

This timely text provides a comprehensive overview of the unique and varied behavior of these combinations. Fifteen specially-written chapters by a team of the world's foremost researchers in the field explore all aspects. X-ray binaries are a class of binary stars that are luminous in X-rays are produced by matter falling from one component, called the donor (usually a relatively normal star), to the other component, called the accretor, which is very compact: a neutron star or black infalling matter releases gravitational potential energy, up to several tenths of its rest mass, as X-rays.

Low–mass X–ray binaries The studies presented in this thesis concern low–mass X–ray binaries (LMXBs). LMXBs are binary systems in which a low–mass companion star (1M) trans-fers matter to a compact object, either a neutron star or a black hole. The compact object is formed in a supernova explosion (although a neutron star might.

A short year review of ultra-compact binaries, focused on ultra-compact X-ray binaries, is followed by a discussion of results of our VLT campaign to obtain optical spectra of (candidate) ultra-compact X-ray binaries.

Mass determinations and X-ray energy spectral analyses are among the methods used to distinguish between the types of compact objects present in X-ray binary systems.

We test a method of distinguishing between neutron stars and black holes proposed by Sunyaev and Revnivtsev where power density spectra are used, particularly in the Hz range.

X-ray spectral variability is a powerful probe of the relationship between the accretion disc and corona in accreting compact objects.

In this thesis, I present the use of variability techniques. Power density spectra in X-ray astronomy In X-ray astronomy, the power density spectrum (PDS) is an indispensable tool for describing and analyzing the frequency content of X-ray radiation.

Many celestial X-ray sources are compact objects that accrete matter from surrounding structures. Relations between X-ray timing features and spectral parameters of Galactic black hole X-ray binaries H.

X-ray energy can be used to calculate the Z of any unknown sample. The logic of this regularity in the X-ray spectra was first laid out by H. Moseley inand he used it to establish the existence of the atomic numbers, resolve the inconsistencies in the placementFile Size: KB.

Spectral-timing products of kilohertz quasi-periodic oscillations (kHz QPOs) in low-mass X-ray binary (LMXB) systems, including energy- and frequency-dependent lags, have been analyzed previously in 4U4Uand 4U Here, we study the spectral-timing properties of the lower Cited by: 2.

Abstract: To confirm the nature of the donor star in the ultra-compact X-ray binary candidate 47 Tuc X9, we obtained optical spectra (3,$-$10, {\AA}) with the Hubble Space Telescope / Space Telescope Imaging Spectrograph.

We find no strong emission or absorption features in the spectrum of X9. In particular, we place $3\sigma$ upper limits on the H$\alpha$ and HeII $\lambda Cited by: 3.

The international conference "Astrophysics of Compact Objects" covered recent observational and theoretical developments in the study of neutron stars, black holes and white dwarfs, including their various observational manifestations such as pulsars, magnetars, x-ray binaries, supernovae and gamma ray bursts, as well as future observational.

Observations of X-ray spectra for four low-mass binary X-ray sources, Sco X-1, 4UGX and GX+2 were performed with the gas scintillation proportional counters on board Tenma. Get this from a library.

X-Ray Binaries and Recycled Pulsars. [E P J Heuvel; S A Rappaport] -- The motivation for the Workshop on which this book is based was the discovery in recent years of a large number of binary and millisecond radio pulsars, in the galactic disk as well as in globular.

Intermediate mass X-ray binaries (Podsiadlowski et al., ApJ ) Most of the evolution time systems spend as an X-ray binary occurs after the mass of the donor star has been reduced to.

In X-ray binaries where the compact object is a Neutron Star, rather than a black hole, the material which falls from the giant star onto the neutron star builds up on the surface. Eventually there is enough material there for it to "burn" like at the centre of a star, and this causes the largest visible thermonuclear flash.

Be/X-ray binaries (BeXRBs) are a class of high-mass X-ray binaries that consist of a Be star and a neutron neutron star is usually in a wide highly elliptical orbit around the Be star. The Be stellar wind forms a disk confined to a plane often different from the orbital plane of the neutron star.

When the neutron star passes through the Be disk, it accretes a large mass of gas in a. High mass x-ray binaries are binary starsystems containing a massive blue O or B class giant star (M > 10 M Sun) revolving around a compact object, which could be a, a neutron star or a black hole.

In HMXB, the massive star dominates the emission of optical light while the accretion disc and the compact object's surface stands for the x-ray.

Abstract: In this paper we present X-Shooter time resolved spectroscopy and RXTE PCA light curves of the ultra-compact X-ray binary candidate 4U + The X-Shooter data are compared to the GMOS data analyzed previously by Nelemans et al. We confirm the presence of C III and O II emission features at ~ {\AA} and ~ {\AA}.Cited by: 5.

Ultra-compact X-ray binaries are very similar binaries to AM CVn systems, but with a neutron star or black hole accretor. See here for a discussion of their formation. Ultra-compact X-ray binaries are mostly studied with X-ray detectors, because they are rather faint in the optical band.

We obtained optical spectra with the VLT and Gemini-North. Egron, Elise X-ray binary systems are composed by two stars which are gravitationally bound to each other: a compact object and a companion star.

The compact object results from the final stages of the evolution of massive stars. According to the mass of the progenitor, a neutron star or a. Transient X-ray binaries consist of a star and an object of high density, called a compact object. The compact objects studied in this thesis are neutron stars, which are the remnants of supernova explosions.

Mass transfer from the companion star onto the neutron star’s surface results in emission of X-rays, which are only observable by X-ray.

Abstract. The connection between cosmic X-ray sources and compact stars is an old one: soon after the discovery of the first such source, Sco X-1 (Giacconi et al.
