    Kinematic and metallicity properties of the Aquarius dwarf galaxy from FORS2 MXU spectroscopy⋆
    Context. Dwarf galaxies found in isolation in the Local Group (LG) are unlikely to have interacted with the large LG spirals, and therefore environmental...

    Kinematic Clues to Bar Evolution for Galaxies in the Local Universe: Why the Fastest Rotating Bars are Rotating Most Slowly
    We have used Spitzer images of a sample of 68 barred spiral galaxies in the local universe to make systematic measurements of bar length and bar strength. We...

    Learning about stars from their colors
    Aims: We pose the question of how much information on the atmospheric parameters of late-type stars can be retrieved purely from color information using...

    Learning to do multiframe wavefront sensing unsupervised: Applications to blind deconvolution
    Context. Observations from ground-based telescopes are severely perturbed by the presence of the Earth's atmosphere. The use of adaptive optics techniques has...

    Limits to the presence of transiting circumbinary planets in CoRoT Data
    Aims: During its flight phase, from 2007-2012, the CoRoT mission delivered light curves for over 2000 eclipsing binaries. Data from the Kepler mission have...
