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...
Line formation in solar granulation. VI. [C I], C I, CH and C2 lines and the photospheric C abundance
The solar photospheric carbon abundance has been determined from [C I], C I, CH vibration-rotation, CH A-X electronic and C2 Swan electronic lines by means of a...
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...
