A dozen colliding wind X-ray binaries in the star cluster R136 in the 30Doradus region [PDF]
, 2002 We analyzed archival Chandra X-ray observations of the central portion of the 30 Doradus region in the Large Magellanic Cloud. The image contains 20 X-ray point sources with luminosities between $5 \times 10^{32}$ and $2 \times 10^{35}$ erg s$^{-1}$ (0.2

Clumpy wind accretion in supergiant neutron star high mass X-ray binaries [PDF]
Astronomy & Astrophysics, 2016 The accretion of the stellar wind material by a compact object represents the main mechanism powering the X-ray emission in classical supergiant high mass X-ray binaries and supergiant fast X-ray transients. In this work we present the first attempt to simulate the accretion process of a fast and dense massive star wind onto a neutron star, taking into

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 evolution and masses of the neutron star and donor star in the high mass X-ray binary OAO 1657-415 [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We report near-infrared radial velocity measurements of the recently identified donor star in the high mass X-ray binary system OAO 1657-415 obtained in the H band using ISAAC on the VLT. Cross-correlation methods were employed to construct a radial velocity curve with a semi-amplitude of $22.1 \pm 3.5$ km s$^{-1}$.
