News on the X-ray emission from hot subdwarf stars [PDF]

open access: yesOpen Astronomy, 2017
In latest years, the high sensitivity of the instruments on-board the XMM-Newton and Chandra satellites allowed us to explore the properties of the X-ray emission from hot subdwarf stars.

Donors of Persistent Neutron-Star Low-Mass X-Ray Binaries [PDF]

open access: yesPublications 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

open access: yesThe 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]

open access: yesNuclear 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]

open access: yes, 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

Chemical abundances of secondary stars in low mass X-ray binaries [PDF]

open access: yesProceedings 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

open access: yesThe 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.

Magnetic Inclination Evolution of Accreting Neutron Stars in Intermediate/Low-mass X-Ray Binaries

open access: yesThe 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
