Globular cluster abundances in the light of 3D hydrodynamical model atmospheres
Abstract
Recently realistic time-dependent 3D hydrodynamical simulations of stellar surface convection have become feasible. Such 3D hydrodynamical model atmospheres often show significant differences in their atmospheric structures compared with existing hydrostatic 1D model atmospheres which directly propagate to differences in the emergent spectrum and the inferred interpretations in terms of for example elemental abundances. In this review I will discuss the impact of the new generation of 3D model atmospheres on the derived abundances for globular clusters concentrating on elements of specific importance for the understanding of the formation and evolution of globular clusters.
