    A statistical study of the optical spectral variability in gamma-ray blazars
    Blazars optical emission is generally dominated by relativistic jets, although the host galaxy, accretion disc, and broad-line region (BLR) may also contribute...

    A stellar disk perpendicular to the radio jet in B2 0034+25
    CCD surface photometry of the radio galaxy B2 0034+25 is reported. Fourier analysis of the intensity variations along a set of closely spaced elliptical...

    A Stellar Model-fitting Pipeline for Asteroseismic Data from the Kepler Mission
    Over the past two decades, helioseismology has revolutionized our understanding of the interior structure and dynamics of the Sun. Asteroseismology will soon...

    A stellar occultation by the transneptunian object (50000) Quaoar observed by CHEOPS
    Context. Stellar occultation is a powerful technique that allows the determination of some physical parameters of the occulting object. The result depends on...

    A stellar overdensity associated with the Small Magellanic Cloud
    We report the discovery of a stellar overdensity 8° north of the centre of the Small Magellanic Cloud (SMC; Small Magellanic Cloud Northern Over-Density; SMCNOD...

    A stellar stream remnant of a globular cluster below the metallicity floor
    Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures...

    A strong correlation between bar strength and global star forming activity in isolated barred galaxies
    I have studied the relation between the global star formation activity and the bar structure in a sample of isolated barred galaxies. The star formation...

    A Strong Dichotomy in S0 Disk Profiles between the Virgo Cluster and the Field
    We report evidence for a striking difference between S0 galaxies in the local field and the Virgo Cluster. While field S0 galaxies have disks whose surface...

    A stronger He II 4686 in the spectrum of the planetary nebula NGC 6572
    On a recent spectrogram of the planetary nebula NGC 6572 the authors have found He II 4686 clearly in emission. They review previous descriptions of the...
