    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...

    Line-profile variations of the double-lined spectroscopic binary kappa Scorpii
    We present a total time series of high signal-to-noise, high-resolution spectra of the SiIII lambda 4552.6, lambda 4567.8 and lambda 4574.8 Å lines of the fast...

    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...

    Linear wavelength correlation matrices of photospheric and chromospheric spectral lines. I. Observations vs. modeling
    Context. The process that heats the solar chromosphere is a difficult target for observational studies because the assumption of local thermal equilibrium (LTE)...

    Lines in the cosmic microwave background spectrum from the epoch of cosmological helium recombination
    The main goal of this work is to calculate the contributions of bound-bound transitions of helium to the cosmological recombination spectrum. We show that...

    Linking star formation thresholds and truncations in the thin and thick disks of the low-mass galaxy UGC 7321
    Thin and thick disks are found in most spiral galaxies, yet their formation scenarios remain uncertain. Whether thick disks form through slow or fast, internal...

    Linking the primordial composition of planet building disks to the present-day composition of rocky exoplanets
    Context. The composition of rocky planets is strongly driven by the primordial materials in the protoplanetary disk, which can be inferred from the abundances...
