Exploration of spin-down rate of neutron stars in high-mass X-ray binaries [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We use the evolutionary population synthesis method to investigate the statistical properties of the wind-fed neutron star (NS) compact ($P_{\rm orb}<10$ days) high-mass X-ray binaries (HMXBs) in our Galaxy, based on different spin-down models. We find that the spin-down rate in the supersonic propeller phase given \textbf{by assuming that the ...

The first mm detection of a neutron star high-mass X-ray binary

Monthly Notices of the Royal Astronomical Society: Letters, 2023
ABSTRACT Neutron stars accreting from OB supergiants are often divided between persistently and transiently accreting systems, called supergiant X-ray binaries (SgXBs) and supergiant fast X-ray transients (SFXTs). This dichotomy in accretion behaviour is typically attributed to systematic differences in the massive stellar wind, binary ...

High-energy emission from jet-clump interactions in microquasars [PDF]

, 2009
High-mass microquasars are binary systems consisting of a massive star and an accreting compact object from which relativistic jets are launched. There is considerable observational evidence that winds of massive stars are clumpy.

Drop in the Hard Pulsed Fraction and a Candidate Cyclotron Line in IGR J16320–4751 Seen by NuSTAR

The Astrophysical Journal, 2023
We report on a timing and spectral analysis of a 50 ks NuSTAR observation of IGR J16320−4751 (= AX J1631.9−4752), a high-mass X-ray binary hosting a slowly rotating neutron star.

Carina OB Stars: X-ray Signatures of Wind Shocks and Magnetic Fields [PDF]

, 2011
The Chandra Carina Complex contains 200 known O- and B type stars. The Chandra survey detected 68 of the 70 O stars and 61 of 127 known B0-B3 stars. We have assembled a publicly available optical/X-ray database to identify OB stars that depart from the ...

High-mass X-ray binaries and recent star formation history of the Small Magellanic Cloud [PDF]

Astronomy Letters, 2007
We study the relation between high-mass X-ray binary (HMXB) population and recent star formation history (SFH) for the Small Magellanic Cloud (SMC). Using archival optical SMC observations, we have approximated the color-magnitude diagrams of the stellar population by model stellar populations and, in this way, reconstructed the spatially resolved SFH ...

The spatial correlation of high-mass X-ray binaries and young star clusters in nearby star-forming galaxies

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT We present an analysis of the two-point spatial correlation functions of high-mass X-ray binary (HMXB) and young star cluster (YSC) populations in M31 and M33. We find evidence that HMXBs are spatially correlated with YSCs to a higher degree than would be expected from random chance in both galaxies.

Formation of Sco X-1 induced by anomalous magnetic braking of Ap/Bp stars

, 2017
Sco X-1 is the brightest persistent X-ray in the sky. It is generally believed that Sco X-1 is a low-mass X-ray binary containing a neutron star accreting from a low-mass donor star where mass transfer is driven by the magnetic braking. However, the mass
