Results

We have calculated a grid of solar abundance model atmospheres and grids with enhanced metallicities $[{\rm M/H}]=+0.3$ as well as reduced metallicities, $[{\rm M/H}]=-0.3$. The models span a range of $2000\,{\rm K}\leq \hbox{$\,T_{\rm eff}$}\leq 6800\,{\rm K}$ and $2.0 \leq \log(g)\leq 3.5$. These models were originally intended to be used for low mass stellar evolution models (Baraffe et al, in preparation) and thus assume a mass of $0.1\hbox{$\,$M$_\odot$}$ for the stars. In the parameter range (mainly $\log(g)$) considered here, the synthetic spectra can also be applied to other masses. Most of the basic results have been described in , so we are concentrating here on comparison with the NG-giant models.
