    An old, metal-poor globular cluster in Sextans A and the metallicity floor of globular cluster systems
    We report the confirmation of an old, metal-poor globular cluster (GC) in the nearby dwarf irregular galaxy Sextans A, the first GC known in this galaxy. The...

    An optical transmission spectrum of the giant planet WASP-36 b
    We present broad-band photometry of five transits in the planetary system WASP-36, totalling 17 high-precision light curves. Four of the transits were...

    An optimized Hβ index for disentangling stellar population ages
    We have defined a new Hβ absorption index definition, Hβo, which has been optimized as an age indicator for old and intermediate age stellar populations. Rather...

    An ultraviolet spectral study of fullerene-rich planetary nebulae
    Several planetary nebulae (PNe) have been found to contain both polycyclic aromatic hydrocarbon (PAH-like) species and fullerenes (C 60) distinguished by their...

    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...

    An XMM-Newton observation of the neutron star X-ray transient 2S 1803-245 in quiescence
    We observed the neutron star X-ray transient 2S 1803-245 in quiescence with the X-ray satellite XMM-Newton, but did not detect it. An analysis of the X-ray...

    An `outside-in' outburst of AQL X-1
    We present optical spectroscopy and optical and infrared photometry of the neutron star soft X-ray transient Aql X-1 during its X-ray outburst of 1997 August...

    Analysis and calibration of CaII triplet spectroscopy of red giant branch stars from VLT/FLAMES observations
    We demonstrate that low-resolution CaII triplet (CaT) spectroscopic estimates of the overall metallicity ([Fe/H]) of individual red giant branch (RGB) stars in...

    Analysis of a spatially deconvolved solar pore
    Solar pores are active regions with large magnetic field strengths and apparent simple magnetic configurations. Their properties resemble the ones found for the...
