    Bow shocks, nova shells, disc winds and tilted discs: the nova-like V341 Ara has it all
    V341 Ara was recently recognized as one of the closest (d ≃ 150 pc) and brightest (V ≃ 10) nova-like cataclysmic variables. This unique system is surrounded by...

    Bowen emission from Aquila X-1: evidence for multiple components and constraint on the accretion disc vertical structure
    We present a detailed spectroscopic study of the optical counterpart of the neutron star X-ray transient Aquila X-1 during its 2011, 2013 and 2016 outbursts. We...

    Bowen Fluorescence from the Companion Star in X1822-371
    We present clear evidence for the motion of the companion star in the low-mass X-ray binary (LMXB) X1822-371. We detect N III λ4640 emission moving in antiphase...

    Broad iron emission line and kilohertz quasi-periodic oscillations in the neutron star system 4U 1636-53
    Both the broad iron (Fe) line and the frequency of the kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low-mass X-ray binaries (LMXBs) can...

    Broad iron line in the fast spinning neutron-star system 4U 1636-53
    We analysed the X-ray spectra of six observations, simultaneously taken with XMM-Newton and Rossi X-ray Timing Explorer (RXTE), of the neutron-star low-mass X...

    Broad-band spectral energy distribution of the X-ray transient Swift J1745-26 from outburst to quiescence
    Aims: We aim to analyse our study of the X-ray transient Swift J1745-26, using observations obtained from its outburst in September 2012, up to its decay...

    Burst-properties as a function of mass accretion rate in GX 3+1
    GX 3+1 is a low-mass X-ray binary that is persistently bright since its discovery in 1964. It was found to be an X-ray burster twenty years ago proving that the...
