  • Publication
    An underlying clock in the extreme flip-flop state transitions of the black hole transient Swift J1658.2-4242
    Aims: Flip-flops are top-hat-like X-ray flux variations, which have been observed in some transient accreting black hole binary systems, and feature...
  • Publication
    An unusual iron Lo-BAL quasar detected by ISOCAM
    We report the discovery of an unusual low-ionization broad absorption line quasar at z=1.776 which exhibits absorption lines from many excited states of Fe II...
  • Publication
    An unusual transient in the extremely metal-poor Galaxy SDSS J094332.35+332657.6 (Leoncino Dwarf)
    We have serendipitously discovered that Leoncino Dwarf, an ultrafaint, low-metallicity record-holder dwarf galaxy, may have hosted a transient source, and...
  • Publication
    An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)
    Context. Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion...
  • Publication
    An updated MILES stellar library and stellar population models
    Aims: We present a number of improvements to the MILES library and stellar population models. We correct some small errors in the radial velocities of the stars...
  • Publication
    An updated stellar census of the Quintuplet cluster
    Context. Found within the central molecular zone, the Quintuplet is one of the most massive young clusters in the Galaxy. As a consequence it offers the...
  • Publication
    An Upper Limit on the Temporal Variations of the Solar Interior Stratification
    We have analyzed changes in the acoustic oscillation eigenfrequencies measured over the past 7 years by the GONG, MDI, and LOWL instruments. The observations...
  • Publication
    An Upper Limit to Ground Deformation in the Island of Tenerife, Canary Islands, for the Period 1997 2006
    Continuous monitoring of ground deformation in the volcanic island of Tenerife, Canary Islands, is based on GPS networks, since there are as yet no tiltmeter...
  • Publication
    An upper limit to the abundance of Be-9 in the Population II star HD 76932 from a high resolution spectrum with IUE
    A high resolution spectrum (Δλ = 0.2 Å) of the Population II star HD 76932 from the archive of the IUE satellite has been analysed in a search for measurable...
