    The Distance, Mass, and Radius of the Neutron Star in 4U 1608-52
    Low-mass X-ray binaries (LMXBs) that show thermonuclear bursts are ideal sources for constraining the equation of state of neutron star matter. The lack of...

    The Double Dust Envelopes of R Coronae Borealis Stars
    The study of extended, cold dust envelopes surrounding R Coronae Borealis (RCB) stars began with their discovery by the Infrared Astronomical Satellite. RCB...

    The double sub-giant branch of NGC 6656 (M 22): a chemical characterization
    We present an abundance analysis of 101 subgiant branch (SGB) stars in the globular cluster M 22. Using low-resolution FLAMES/GIRAFFE spectra we have determined...

    The early days of the Sculptor dwarf spheroidal galaxy
    We present the high-resolution spectroscopic study of five -3.9 ≤ [Fe/H] ≤ -2.5 stars in the Local Group dwarf spheroidal, Sculptor, thereby doubling the number...

    The effect of tides on the Fornax dwarf spheroidal galaxy
    Estimates of the mass distribution and dark-matter (DM) content of dwarf spheroidal galaxies (dSphs) are usually derived under the assumption that the effect of...

    The effect of tides on the Sculptor dwarf spheroidal galaxy
    Dwarf spheroidal galaxies (dSphs) appear to be some of the most dark matter (DM)-dominated objects in the Universe. Their dynamical masses are commonly derived...

    The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
    The eighteenth data release (DR18) of the Sloan Digital Sky Survey (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises...

    The Eleventh and Twelfth Data Releases of the Sloan Digital Sky Survey: Final Data from SDSS-III
    The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an...

    The entropy of galaxy spectra: how much information is encoded?
    The inverse problem of extracting the stellar population content of galaxy spectra is analysed here from a basic standpoint based on information theory. By...
