    Lower atmosphere and pressure evolution on Pluto from ground-based stellar occultations, 1988-2016
    Context. The tenuous nitrogen (N2) atmosphere on Pluto undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has recently (July...
  • Publication
    Lucky Imaging of M subdwarfs
    Context: The knowledge of the binary properties of metal-poor and solar-metallicity stars can shed light on the potential differences between the formation...

    Lucky spectroscopy, an equivalent technique to lucky imaging. II. Spatially resolved intermediate-resolution blue-violet spectroscopy of 19 close massive binaries using the William Herschel Telescope
    Context. Many massive stars have nearby companions. These hamper a characterization of massive stars through spectroscopy. Aims: We continue to obtain spatially...
