Donors of Persistent Neutron-Star Low-Mass X-Ray Binaries [PDF]
Publications of the Astronomical Society of the Pacific, 2012 Properties of X-ray luminosities in low-mass X-ray binaries (LMXBs) mainly depend on donors. We have carried out a detailed study of donors in persistent neutron-star LMXBs (PLMXBs) by means of a population synthesis code. PLMXBs with different donors have different formation channels.

PSR J1953+1844 Probably Being the Descendant of an Ultracompact X-Ray Binary
The Astrophysical Journal Letters, 2023 PSR J1953+1844 (i.e., M71E) is a millisecond pulsar in a 53 minute binary orbit discovered by the Five-hundred-meter Aperture Spherical radio Telescope. The mass function from pulsar timing is 2.3 × 10 ^−7 M _⊙ .

Rapid X-ray variability of neutron stars in low-mass binary systems [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 The dramatic discovery with the Rossi X-Ray Timing Explorer satellite of remarkably coherent $\sim$300--1200 Hz oscillations in the X-ray brightness of some sixteen neutron stars in low-mass binary systems has spurred theoretical modeling of these oscillations and investigation of their implications for the neutron stars and accretion flows in these ...

Simulations of X-ray bursts and superbursts [PDF]
, 2015 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

Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]
, 2012 We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

Wide binary stars in the Galactic field : a statistical approach [PDF]
, 2010 This thesis focuses on the statistical properties of wide binary (WB) star systems in the Galactic field. With projected separations larger than 200 AU and, consequently, having very low binding energies, WB are sensitive probes of the Galactic ...

Magnetic Inclination Evolution of Accreting Neutron Stars in Intermediate/Low-mass X-Ray Binaries
The Astrophysical Journal, 2023 The magnetic inclination angle χ , namely the angle between the spin and magnetic axes of a neutron star, plays a vital role in its observational characteristics. However, there are few systematic investigations of its long-term evolution, especially for

Chemical abundances of secondary stars in low mass X-ray binaries [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractLow mass X-ray binaries (LMXBs) offer us an unique opportunity to study the formation processes of compact objects. Secondary stars orbiting around either a black hole or a neutron star could have captured a significant amount of the ejected matter in the supernova explosions that most likely originated the compact objects.

Constraints on Neutron Star Structure from the Clocked X-Ray Burster 1RXS J180408.9−342058
The Astrophysical Journal, 2023 Type I X-ray bursts are rapid-brightening transient phenomena on the surfaces of accreting neutron stars (NSs). Some X-ray bursts, called clocked bursters, exhibit regular behavior with similar light-curve profiles in their burst sequences.
