    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 ˜24 years. The RRLs display a spread in V-magnitude (˜0.35 mag) which appears larger than photometric errors and the horizontal branch (HB) luminosity evolution of a mono-metallic

    Variation of Galactic Bar Length with Amplitude and Density as Evidence for Bar Growth over a Hubble Time
    Ks-band images of 20 barred galaxies show an increase in the peak amplitude of the normalized m=2 Fourier component with the R25-normalized radius at this peak. This implies that longer bars have higher m=2 amplitudes. The long bars also correlate with an increased density in the central parts of the disks, as measured by the luminosity inside 0

    Velocity Fields within the Solar Convection Zone: Evidence from Oscillation Ring Diagram Analysis of Mount Wilson Dopplergrams
    A ring-diagram analysis of solar oscillations has been applied to a 3 day time series of full-disk Doppler images obtained at Mount Wilson. A model of the three-dimensional power spectrum assuming a Lorentzian profile in frequency and the advection of the wave front by horizontal flows has been fitted to the observed spectrum. The model provides

    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. This kinematic information is connected to dynamical aspects in the formation and evolution of the Milky Way, such as the passage of satellites and vertical resonance and determines whether the
