Early neutron star evolution in high-mass X-ray binaries [PDF]

open access: yesMonthly 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.

Feeding Neutron Stars in High-Mass X-ray Binaries [PDF]

open access: yesProceedings 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.

Evolution of neutron stars in high-mass X-ray binaries [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
We consider the evolution of neutron stars during the X-ray phase of high-mass binaries. Calculationsareperformedassumingacrustal originofthemagneticfield.Astrongwindfrom the companion can significantly influence the magnetic and spin behaviour of a neutron star even during the main-sequence life of the companion.

The Spin-down Accretion Regime of Galactic Ultraluminous X-Ray Pulsar Swift J0243.6+6124

open access: yesThe Astrophysical Journal, 2023
The relatively high fluxes of the Galactic ultraluminous X-ray pulsar Swift J0243 allow a detailed study of its spin-down regime in the quiescent state for the first time.

Constraints to neutron-star kicks in high-mass X-ray binaries withGaiaEDR3

open access: yesAstronomy & Astrophysics, 2022
Context.All neutron star progenitors in neutron-star high-mass X-ray binaries (NS HMXBs) undergo a supernova event that may lead to a significant natal kick impacting the motion of the whole binary system. The space observatoryGaiaperforms a deep optical survey with exquisite astrometric accuracy, for both position and proper motions, that can be used ...

Multiwavelength Characterization of the High-mass X-Ray Binary Population of M33

open access: yesThe Astrophysical Journal, 2023
We present multiwavelength characterization of 65 high-mass X-ray binary (HMXB) candidates in M33. We use the Chandra ACIS survey of M33 (ChASeM33) catalog to select hard X-ray point sources that are spatially coincident with UV-bright point-source ...

The masses of the neutron and donor star in the high-mass X-ray binary IGR J18027-2016 [PDF]

open access: yesAstronomy & Astrophysics, 2011
We report near-infrared observations of the supergiant donor to the eclipsing high mass X-ray binary pulsar IGR J18027-2016. We aim to determine its spectral type and measure its radial velocity curve and hence determine the stellar masses of the components.

Unveiling Properties of the Nonthermal X-Ray Production in the Gamma-Ray Binary LS 5039 Using the Long-term Pattern of Its Fast X-Ray Variability

open access: yesThe Astrophysical Journal, 2023
Gamma-ray binary systems, a subclass of high-mass X-ray binaries, show nonthermal emissions from radio to TeV. While efficient electron acceleration is considered to take place in them, the nature of the acceleration mechanism and the physical ...

A NICER Viewing Angle on the Accretion Stream of Vela X-1

open access: yesThe Astrophysical Journal, 2023
Vela X-1 is the archetypal eclipsing high-mass X-ray binary, composed of a neutron star (NS) accreting the B-star wind. It was observed by nearly all X-ray observatories, often multiple times, featuring a rich spectrum of variable emission lines. However,

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

open access: yesMonthly 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 ...
