    Li abundances in F stars: planets, rotation, and Galactic evolution
    Aims: We aim, on the one hand, to study the possible differences of Li abundances between planet hosts and stars without detected planets at effective...

    Li depletion in solar analogues with exoplanets. Extending the sample
    Aims: We want to study the effects of the formation of planets and planetary systems on the atmospheric Li abundance of planet host stars. Methods: In this work...

    Limited impact of jet-induced feedback in the multi-phase nuclear interstellar medium of 4C12.50
    Context. 4C12.50 (IRAS 13451+1232) at z = 0.122 is an ultraluminous infared radio galaxy that has often been proposed as a prime candidate for the link between...

    Limits on the orbits and masses of moons around currently-known transiting exoplanets
    Aims: Current and upcoming space missions may be able to detect moons of transiting extra-solar planets. In this context it is important to understand if...

    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...
