DOI: 10.1051/0004-6361/202039278
Abstract: Context. We have presented a numerical model for the non-thermal emission of gamma-ray binaries in a pulsar-wind driven scenario. Aims. We apply this model to one of the best-observed gamma-ray binaries, the LS 5039 system.… read more here.

DOI: 10.1088/1674-4527/ac3125
Abstract: Using the apparent correlation of luminosity (LX) versus displacement (R) of high mass X-ray binaries (HMXBs), we aim to constrain the common envelope (CE) mechanism, which is vital in the formation and evolution of compact… read more here.

DOI: 10.1088/1748-0221/16/09/c09025
Abstract: X-ray binaries (XRBs) are binary systems with an accreting compact object. They have long been suggested to be possible galactic cosmic ray (CR) accelerators. In such models, the protons accelerated by the accretion process at… read more here.

DOI: 10.1093/mnras/staa1193
Abstract: Infrared interferometry is a new frontier for precision ground based observing, with new instrumentation achieving milliarcsecond (mas) spatial resolutions for faint sources, along with astrometry on the order of 10 microarcseconds. This technique has already… read more here.

DOI: 10.1093/mnras/staa675
Abstract: The application of standard accretion theory to observations of X-ray binaries provides valuable insights into neutron star properties, such as their spin period and magnetic field. However, most studies concentrate on relatively old systems, where… read more here.

DOI: 10.1093/mnras/stab1995
Abstract: 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 sources include 13 weakly magnetized (B <… read more here.

Towards a larger sample of radio jets from quiescent black hole X-ray binaries

DOI: 10.1093/mnras/stab644
Abstract: Quiescent black hole X-ray binaries (X-ray luminosities ${\lesssim} 10^{34}\,{\rm erg}\, {\rm s}^{-1}$) are believed to be fed by hot accretion flows that launch compact, relativistic jets. However, due to their low luminosities, quiescent jets have… read more here.

DOI: 10.1093/mnras/stx1430
Abstract: We show that black hole high-mass X-ray binaries (HMXBs) with O- orB-type donor stars and relatively short orbital periods, of order oneweek to several months may survive spiral-in, to then form Wolf-Rayet(WR) X-ray binaries with… read more here.

DOI: 10.1093/mnras/stx3211
Abstract: 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 donor, a fraction of which is… read more here.
