New improvements in the measurement of both the optical solar spectrum and laboratory wavelengths for lines of neutral iron are combined to extract central wavelength shifts for 1446 lines observed in the Sun. This provides the largest available database of accurate solar wavelengths useful as a reference for comparison with other solar-type stars. It is shown how the velocity shifts correlate with line strength, approaching a constant value, close to zero, for lines with equivalent widths larger than 200 mA.

  1. Towards understanding stellar variability at the sub m/s level: granulation-induced variability across the optical spectrum

    astro-ph.SR 2026-08 conditional novelty 6.0

    Using 3D solar simulations, 72 spectral lines show that weak lines have the largest granulation-induced RV variability (up to 40–50 m/s), strong lines vary most in equivalent width, and most lines' RV and width change...

  2. 3D Non-LTE radiation transfer: theory and applications to stars, exoplanets, and kilonovae

    astro-ph.SR 2025-11 conditional novelty 2.0

    A field review of 3D non-LTE radiative transfer argues that 1D LTE treatments of stellar, exoplanet, and kilonova spectra carry systematic abundance biases that 3D NLTE modeling can now remove.
