    Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
    Context. The lack of high-precision long-term continuous photometric data for large samples of stars has impeded the large-scale exploration of pulsational...

    Variable stars in Local Group Galaxies - I. Tracing the early chemical enrichment and radial gradients in the Sculptor dSph with RR Lyrae stars
    We identified and characterized the largest (536) RR Lyrae (RRL) sample in a Milky Way dSph satellite (Sculptor) based on optical photometry data collected over...

    Variable stars in local group galaxies - IV. RR Lyrae stars in the central regions of the low-density galaxy Crater II
    We present a search and analysis of variable stars in the recently discovered Crater II dwarf galaxy. Based on B, V, I data collected with the Isaac Newton...
  • Publication
    Variable stars in Local Group galaxies - V. The fast and early evolution of the low-mass Eridanus II dSph galaxy
    We present a detailed study of the variable star population of Eridanus II (Eri II), an ultra-faint dwarf galaxy that lies close to the Milky Way virial radius...

    Variable Stars in Local Group Galaxies. III. And VII, NGC 147, and NGC 185: Insight into the Building Blocks of the M31 Halo
    We present the discovery of 1568 RR Lyrae stars in three of the most luminous M31 satellites: And VII (573), NGC 147 (177), and NGC 185 (818). We use their...

    Variable Stars in Local Group Galaxies. VI. The Isolated Dwarfs VV 124 and KKr 25
    We present the discovery of variable stars in two isolated dwarf galaxies in the outskirts of the Local Group, VV 124 and KKr 25, using observations with the...

    Variable stars in the Cetus dwarf spheroidal galaxy: population gradients and connections with the star formation history
    We investigate the variable star content of the isolated, Local Group, dwarf spheroidal (dSph) galaxy Cetus. Multi-epoch, wide-field images collected with the...

    Vertical velocities from proper motions of red clump giants
    Aims: We derive the vertical velocities of disk stars in the range of Galactocentric radii of R = 5 - 16 kpc within 2 kpc in height from the Galactic plane...
