    Dynamics of dust around a rotating star
    The orbital evolution of dust particles initially located outside the equatorial plane is considered. The averaging method is used to solve equations of motion...

    Extracting rotation rates on 27-d TESS-like light curves downgrading Kepler data
    Evolution of surface magnetic features in the star, such as stellar spots or faculae, can leave a signature in the lightcurves. These features allow us to study...

    Giant white-light flares on fully convective stars occur at high latitudes
    In a systematic analysis of fully convective stars observed with TESS, we detected four stars that displayed giant flares that were...

    High velocity clouds around nearby galaxies from THINGS
    As a sub-set of activities within the THINGS (The HI Nearby Galaxy Survey) collaboration we have used the HI maps of the complete set of galaxies observed in...

    IAU G5: "Extreme Precision Stellar Spectroscopy"
    The new generation of spectrometers designed for extreme precision radial velocities enable correspondingly precise stellar spectroscopy. It is now fruitful to...

    IUE MG II doublet observations in F and G main sequence stars
    Mg II resonance lines at 2800 A were studied in the spectra of F and G main sequence stars, observed with the IUE satellite in high resolution mode. Correlation...

    Lithium and rotation in the Hyades late F and G stars
    Selecting stars with previously measured or estimated rotational periods we have measured equivalent widths of the Li doublet (6708 A) in 8 stars of the Hyades...

    Lithium in T Tauri stars
    The lithium abundance in 26 T Tauri stars is derived using data taken at the Isaac Newton Telescope and data from literature. The aim is to understand the...

    Magnetic Activity Evolution of Solar-like Stars. I. S <SUB>ph</SUB>-Age Relation Derived from Kepler Observations
    The ages of solar-like stars have been at the center of many studies such as exoplanet characterization or Galactic-archeology. While ages are usually computed...
