    Limits to the planet candidate GJ 436c
    We report on H-band, ground-based observations of a transit of the hot Neptune GJ 436b. Once combined to achieve sampling equivalent to archived observations...

    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...

    Line formation in solar granulation. I. Fe line shapes, shifts and asymmetries
    Realistic ab-initio 3D, radiative-hydrodynamical convection simulations of the solar granulation have been applied to Fe i and Fe ii line formation. In contrast...

    Line formation in solar granulation. IV. [O I], O I and OH lines and the photospheric O abundance
    The solar photospheric oxygen abundance has been determined from [O I], O I, OH vibration-rotation and OH pure rotation lines by means of a realistic time...

    Linear polarization of rapidly rotating ultracool dwarfs
    Aims: We aim to study the near-infrared linear polarization signal of rapidly rotating ultracool dwarfs with spectral types ranging from M7 through T2 and...
