Red giant model atmospheres. I - A grid of opacity sampled models

Abstract

The paper presents a grid of model atmospheres for the effective temperature range 2500-4000 K and the log g range 0.0-2.0. The models are computed under the classical assumptions but include detailed consideration of the bound-bound opacity due to atoms, CO, CN, C2, TiO, CH, NH, MgH, and OH. Bound-bound opacity due to H2O is included in the straight mean approximation.
