Interpolation of spectra from 3D model atmospheres
S. Bertran de Lis, C. Allende Prieto, H. -G. Ludwig +1
The use of 3D hydrodynamical simulations of stellar surface convection for model atmospheres is computationally expensive. Although these models have been available for quite some…

Cosmic variance in [O/Fe] in the Galactic disk
S. Bertran de Lis, C. Allende Prieto, S. R. Majewski +11
We examine the distribution of the [O/Fe] abundance ratio in stars across the Galactic disk using H-band spectra from the Apache Point Galactic Evolution Experiment (APOGEE). We mi…
