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

The 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 ...

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 ...

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

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 ...

The attenuation of atmospheric Cerenkov photons [PDF]
, 2002 Whilst the atmosphere places a limit on the successful applications of many branches of astronomy, it becomes an invaluable tool for the detection of very high energy γ-rays. This thesis is concerned with reducing the systematic uncertainties inherent to

The radial velocity of the companion star in the low-mass X-ray binary 2S 0921-630 : limits on the mass of the compact object [PDF]
, 2005 In this paper we report on optical spectroscopic observations of the low-mass X-ray binary 2S 0921–630 obtained with the Very Large Telescope. We found sinusoidal radial velocity variations of the companion star with a semi-amplitude of 99.1 ± 3.1 km s−1
