Abstract

The main limitation of atmosphere models of late-type stars is the, at best, sketchy treatment of convection. Because the top of the outer convection zone of such stars is located in the photosphere, convection has a large effect on both the atmospheric structure and the emergent spectrum. I present the first results from a grid of 3D, non-grey, radiation-coupled, convection simulations for a range of atmospheric parameters. These results include calibration of the mixing-length, T -τ relations and granulation spectra.
