    Constraining the magnetic vector in the quiet solar photosphere and the impact of instrumental degradation
    Context. With the advent of next generation high resolution telescopes, our understanding of how the magnetic field is organized in the internetwork (IN)...

    Constraining the oblateness of transiting planets with photometry and spectroscopy
    Rapid planetary rotation can cause the equilibrium shape of a planet to be oblate. While planetary oblateness has mostly been probed by examining the subtle...

    Constraining the overcontact phase in massive binary evolution. II. Period stability of known O+O overcontact systems
    Context. Given that mergers are often invoked to explain many exotic phenomena in massive star evolution, understanding the evolutionary phase directly...

    Constraining the overcontact phase in massive binary evolution: III. Period stability of known B+B and O+B overcontact systems
    Context. Binary systems play a crucial role in massive star evolution. Systems composed of B-type and O-type stars are of particular interest due to their...

    Constraining the reflective properties of WASP-178 b using CHEOPS photometry
    Context. Multiwavelength photometry of the secondary eclipses of extrasolar planets is able to disentangle the reflected and thermally emitted light radiated...

    Constraining the solar neighbourhood age-metallicity relation from white dwarf-main sequence binaries
    The age-metallicity relation (AMR) is a fundamental tool for constraining the chemical evolution of the Galactic disc. In this work, we analyse the...

    Constraints of a pulsation frequency on stellar parameters in the eclipsing spectroscopic binary system V577 Oph
    We present a preliminary spectroscopic analysis of the binary system V577Oph, observed during the summer of 2007 on the 2.6 m NOT telescope on La Palma. We have...

    Constraints on Jupiters from observations of Galactic bulge microlensing events during 2000
    We present observations of eight Galactic bulge microlensing events taken with the 1.0-m Jacobus Kapteyn Telescope (JKT) on La Palma during 2000 June and July...

    Constraints on the exosphere of CoRoT-7b
    Context. The small radius and high density of CoRoT-7b implies that this transiting planet belongs to a different species than all transiting planets previously...
