Present grids of stellar atmosphere models are the workhorses in interpreting
stellar observations, and determining their fundamental parameters. These
models rely on greatly simplified models of convection, however, lending less
predictive power to such models of late type stars.
We present a grid of improved and more reliable stellar atmosphere models of
late type stars, based on deep, 3D, convective, stellar atmosphere simulations.
This grid is to be used in general for interpreting observations, and improve
stellar and asteroseismic modeling.
We solve the Navier Stokes equations in 3D and concurrent with the radiative
transfer equation, for a range of atmospheric parameters, covering most of
stellar evolution with convection at the surface. We emphasize use of the best
available atomic physics for quantitative predictions and comparisons with
observations.
We present granulation size, convective expansion of the acoustic cavity,
asymptotic adiabat, as function of atmospheric parameters. These and other
results are also available in electronic form.Comment: 16 pages, 12 figures. Accepted for publication in ApJ, 201
