Ultracompact X-ray binary stars [PDF]
Ultracompact X-ray binary stars usually consist of a neutron star and a white dwarf, two stars bound together by their strong gravity and orbiting each other very rapidly, completing one orbit in less than one hour. Neutron stars are extremely compact remnants of the collapsed cores of massive stars which end their lives in supernova explosions.

Physics of Binary Star Evolution:From Stars to X-ray Binaries and Gravitational Wave Sources [PDF]
Physics of Binary Star Evolution is an up-to-date textbook on the astrophysics and evolution of binary star systems. Theoretical astrophysicists Thomas Tauris and Edward van den Heuvel cover a wide range of phenomena and processes, including mass transfer and ejection, common envelopes, novae and supernovae, X-ray binaries, millisecond radio pulsars ...

The circumstellar environments of Be stars in X-ray binaries [PDF]
This thesis contains results from a long-term campaign to monitor the behaviour of Be/X-ray binary systems at multiple wavelengths. The work presented in this thesis concentrates on the application of Be/X-ray binary observations to contribute to the understanding of the Be star phenomenon itself.

The X-ray emission of Be+stripped star binaries★
ABSTRACT Using observations from Chandra, Swift, and XMM-Newton, we investigate the high-energy properties of all known (18) Be+sdO systems as well as seven additional Be binaries suspected to harbour stripped stars. The observed X-ray properties are found to be similar to those observed for other Be samples.

X-ray emission from massive stars: lessons learned and remaining mysteries [PDF]
Nearly all types of massive stars are known to display X-ray emission at some level. Tremendous insight into this phenomenon has been gained thanks to the sensitivity of the current generation of X-ray satellites and X-ray observations are nowadays an ...

The Binary X-Ray Stars – the Observational Picture [PDF]
When X-ray sources in the galaxy were discovered in 1962 (Giacconi et al., 1962) it was only possible to speculate on their nature, which centered on supernova and cosmic-ray phenomena since these were the only very energetic events known. In particular, the discovery of an X-ray source associated with the Crab Nebula led to the idea that the emission ...

An X-Ray-dim “Isolated” Neutron Star in a Binary?
Abstract We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hr. Combining the radial velocity from LAMOST observations and modeling of the multiband light curve, one obtains a mass function of ≃0.131 M ⊙, an inclination of

Simulations of X-ray bursts and superbursts [PDF]
Observations of neutron star in binary systems provide powerful constrains on the physics at the surface of neutron stars. During the accretion of matter from the companion star, periodic nuclear explosion are triggered in the outer layers of the neutron

Masses of Neutron Stars in X-ray Binary Systems [PDF]
The masses of 6 neutron stars have now been established through studies of binary X-ray and radio pulsars. All of the masses are found to be consistent with, but not necessarily constrained to, the range 1.2–1.6 M⊙. In this talk we discuss the methods and assumptions used in determining the masses of neutron stars in binary X-ray pulsar systems.

Radio Emitting X-ray Binary Stars [PDF]
Some of the most astrophysically interesting objects are found among the radio-emitting X-ray binary stars (REXRB). The class includes the well-studied objects such as SS 433, Cyg X-3 and Sco X-1. The recent discoveries of relativistic ejection of radio knots in the X-ray transients 1915+105 (Mirabel & Rodriguez 1994) and 1655–40 (Hjellming & ...
