    An ancient system hidden in the Galactic plane?
    We analyse high signal-to-noise ESPaDOnS/CFHT spectra of 20 very metal-poor (VMP) stars ([Fe/H] $\,\lt\,-2.0$) in the solar neighbourhood (within $\sim 2$ kpc)...

    An anticorrelation between X-ray luminosity and Hα equivalent width in X-ray binaries
    We report an anticorrelation between continuum luminosity and the equivalent width (EW) of the Hα emission line in X-ray binary systems. The effect is evident...

    An application of an optimal statistic for characterizing relative orientations
    We present the projected Rayleigh statistic (PRS), a modification of the classic Rayleigh statistic, as a test for non-uniform relative orientation between two...

    An archaeoastronomical approach to Roman urbanism: orientation of Roman settlement across the Empire.
    In this work we try to identify if there exist specific patterns in the orientation of Roman towns and military settlements across the Roman Empire, and whether...

    An archaeology of the sky in Gaul in the Augustan period
    Ancient Gaul was transformed during the reign of Augustus (r. 31 BC–14 AD) through a major programme of city building. The new Roman cities were constructed...

    An arcsecond view at 1-2 GHz into the Galactic Bulge
    We present the results of a high angular resolution (1.1 arcsec) and sensitivity (maximum of ~0.1 mJy) radio survey at 1-2 GHz in the Galactic Bulge. This...

    An artificial impact on the asteroid (162173) Ryugu formed a crater in the gravity-dominated regime
    The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile structure. We describe an impact experiment on Ryugu using Hayabusa2’s...

    An artificial neural network approach to the solution of molecular chemical equilibrium
    A novel approach is presented for the solution of instantaneous chemical equilibrium problems. The chemical equilibrium can be considered, due to its...

    An asteroseismic study of the β Cephei star 12 Lacertae: multisite spectroscopic observations, mode identification and seismic modelling
    We present the results of a spectroscopic multisite campaign for the β Cephei star 12 (DD) Lacertae. Our study is based on more than thousand high-resolution...
