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

On Neutron Star Natal Kicks in High-mass X-Ray Binaries: Insights from Population Synthesis
The Astrophysical JournalThe motion of neutron stars (NSs) in the Galaxy is largely dependent on natal kicks received by the NSs during supernova explosions. Thus, the measured peculiar velocities of NS high-mass X-ray binaries (HMXBs) provide valuable clues to natal kicks ...

The Astrophysical JournalBinary stars are responsible for many unusual astrophysical phenomena, including some important explosive cosmic events. The stability criteria for rapid mass transfer and common-envelope evolution are fundamental to binary star evolution. They determine

Spectral Energy Distributions of Southern Binary X-Ray Sources
The Astrophysical Journal Supplement Series, 2023 The rapid variability of X-ray binaries (XRBs) produces a wide range of X-ray states that are linked to activity across the electromagnetic spectrum. It is particularly challenging to study a sample of sources large enough to include all types in their ...

High-Mass X-Ray Binaries and OB Runaway Stars [PDF]
International Astronomical Union Colloquium, 2004 AbstractHigh-mass X-ray binaries (HMXBs) represent an important phase in the evolution of massive binary systems and provide fundamental information on the properties of the OB-star primaries and their compact secondaries (neutron star, black hole). Recent observations indicate that the neutron stars in some of these systems (Vela X-1, 4U 1700-37) are ...

Early neutron star evolution in high-mass X-ray binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The application of standard accretion theory to observations of X-ray binaries provides valuable insights into neutron star (NS) properties, such as their spin period and magnetic field. However, most studies concentrate on relatively old systems, where the NS is in its late propeller, accretor, or nearly spin equilibrium phase.

Clumpy Wind Studies and the Nondetection of a Cyclotron Line in OAO 1657–415
The Astrophysical Journal, 2023 Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass-loss rates. In high-mass X-ray binaries (HMXBs), the compact object can be used as an orbiting X-ray point source to probe the wind and ...

The High Mass X-ray binaries in star-forming galaxies [PDF]
Proceedings of the International Astronomical Union, 2018 AbstractThe high mass X-ray binaries (HMXBs) provide an exciting framework to investigate the evolution of massive stars and the processes behind binary evolution. HMXBs have shown to be good tracers of recent star formation in galaxies and might be important feedback sources at early stages of the Universe.

Feeding Neutron Stars in High-Mass X-ray Binaries [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractWe suggest that the Be/X-ray binary SXP 1062 and the supergiant fast X-ray transient AX J1841.0-0536 belong to accreting magnetars and anti-magnetars, respectively.
