Granulation signatures in the spectrum of the very metal-poor red giant HD122563
I. Ramirez, R. Collet, D. L. Lambert +2
A very high resolution (R=200,000), high signal-to-noise ratio (S/N=340) blue-green spectrum of the very metal-poor ([Fe/H]=-2.6) red giant star HD122563 has been obtained by us at…

Chemical Abundances from Inversions of Stellar Spectra: Analysis of Solar-Type Stars with Homogeneous and Static Model Atmospheres
Carlos Allende Prieto, Paul S. Barklem, Martin Asplund +1
Spectra of late-type stars are usually analyzed with static model atmospheres in local thermodynamic equilibrium (LTE) and a homogeneous plane-parallel or spherically symmetric geo…
