High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as
in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology …

We report new radio observations of a sample of 36 neutron star (NS) X-ray binaries, more
than doubling the sample in the literature observed at current-day sensitivities. These …

Recent observations of the high-mass X-ray binary Cygnus X-1 have shown that both the
companion star (41 solar masses) and the black hole (21 solar masses) are more massive …

Context. In supergiant X-ray binaries (SgXB), a compact object captures a fraction of the
wind of an O/B supergiant on a close orbit. Proxies exist to evaluate the efficiency of mass …

Because of its complex clumpy wind, prominent cyclotron resonant scattering features,
intrinsic variability, and convenient physical parameters (close distance, high inclination …

High-mass X-ray binaries (HMXBs) offer a unique opportunity to investigate accretion onto
compact objects and the wind structure in massive stars. A key source for such studies is the …

Context. In the Milky Way,∼ 18 Wolf-Rayet+ O star (WR+ O) binaries are known with
estimates of their stellar and orbital parameters. Whereas black hole+ O star (BH+ O) …

Supergiant X-ray binaries (sgxb) host a compact object, often a neutron star (NS), orbiting an
evolved O/B star. Mass transfer proceeds through the intense line-driven wind of the stellar …

We propose the development of X-ray interferometry (XRI), to reveal the Universe at high
energies with ultra-high spatial resolution. With baselines which can be accommodated on a …

We present an analysis of three Chandra High Energy Transmission Gratings observations
of the black hole binary Cyg X-1/HDE 226868 at different orbital phases. The stellar wind …
