Signatures of Granulation in the Spectra of K-Dwarfs
I. Ramirez, C. Allende Prieto, D. L. Lambert +1
Very high resolution (R>150,000) spectra of a small sample of nearby K-dwarfs have been acquired to measure the line asymmetries and central wavelength shifts caused by convective…

Line formation in solar granulation: I. Fe line shapes, shifts and asymmetries
M. Asplund, AA. Nordlund, R. Trampedach +2
Realistic ab-initio 3D, radiative-hydrodynamical convection simulations of the solar granulation have been applied to FeI and FeII line formation. In contrast to classical analyses…
