    On the ultracompact nature of 4U1822-000
    We report the discovery of a periodic modulation in the optical lightcurve of the candidate ultracompact X-ray binary 4U1822-000. Using time-resolved optical...

    On the use of field RR Lyrae as galactic probes - VI. Mixed mode RR Lyrae variables in Fornax and in nearby dwarf galaxies
    We investigate the properties of the mixed-mode (RRd) RR Lyrae (RRL) variables in the Fornax dwarf spheroidal (dSph) galaxy by using B- and V-band time series...

    On the validity of quasi-linear kinematic mean-field electrodynamics in astrophysical flows
    Mean-field theory in its kinematic form with the quasi-linear approximation is widely used for the modelling of the transport of weak magnetic fields in...

    On ɛ-mechanism-driven pulsations in VV 47
    We report new observations of the central star of the planetary nebula VV 47 carried out to verify earlier assertions that the short-period pulsation modes...

    On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
    The performance of adaptive optics systems is partially dependent on the algorithms used within the real-time control system to compute wavefront slope...

    Once in a blue moon: detection of `bluing' during debris transits in the white dwarf WD 1145+017
    The first transiting planetesimal orbiting a white dwarf was recently detected in K2 data of WD 1145+017 and has been followed up intensively. The multiple...

    One simulation to have them all: performance of the Bias Assignment Method against N-body simulations
    In this paper, we demonstrate that the information encoded in one single (sufficiently large) N-body simulation can be used to reproduce arbitrary numbers of...

    Ongoing star formation at the outskirts of Sextans A: spectroscopic detection of early O-type stars
    With both nebular- and stellar-derived abundances of ≲1/10 Z_{⊙ } and low foreground extinction, Sextans A is a prime candidate to replace the Small Magellanic...

    Optical and infrared diagnostics of SDSS galaxies in the SWIRE survey
    We present the rest-frame optical and infrared colours of a complete sample of 1114 z 0.3 galaxies from the Spitzer Wide-Area Infrared Extragalactic (SWIRE)...
