    An eclipsing double-line spectroscopic binary at the stellar/substellar boundary in the Upper Scorpius OB association
    Aims: We aim at constraining evolutionary models at low mass and young ages by identifying interesting transiting system members of the nearest OB association...
  • Publication
    An eclipsing post-common-envelope binary in the field of the Kepler mission
    We present a new eclipsing post-common-envelope binary, identified inside the Kepler field prior to the launch of the spacecraft. Multifilter photometry and...
  • Publication
    An eclipsing substellar binary in a young triple system discovered by SPECULOOS
    Mass, radius and age are three of the most fundamental parameters for celestial objects, enabling insight into the evolution and internal physics of stars...
  • Publication
    An effective temperature calibration for solar type stars using equivalent width ratios. A fast and easy spectroscopic temperature estimation
    Aims: Precise determination of the stellar effective temperature of solar type stars is extremely important for astrophysics. We present an effective...
  • Publication
    An Effective Temperature Scale for Late-M and L Dwarfs, from Resonance Absorption Lines of Cs I and Rb I
    We present Keck HIRES spectra of six late-M dwarfs and 11 L dwarfs. Our goal is to assign effective temperatures to the objects using detailed atmospheric...
  • Publication
    An Elemental Assay of Very, Extremely, and Ultra-metal-poor Stars
    We present a high-resolution elemental-abundance analysis for a sample of 23 very metal-poor ([Fe/H]
  • Publication
    An elevation of 0.1 light-seconds for the optical jet base in an accreting Galactic black hole system
    Relativistic plasma jets are observed in many systems that host accreting black holes. According to theory, coiled magnetic fields close to the black hole...

    An ellipsoidal modulation in Nova Ophiuchi 1977 (=H1705-25=V2107 Oph)
    We report the detection of an orbital, ellipsoidal modulation at a period of 16.8h for V2107 Oph (Nova Ophiuchi 1977, H1705-25), from R-band photometry. From...
