Interpolation of Stellar Model Grids and Application to the NEMO Grid

NEMO.2003 (vienna NEw MOdel grid of stellar atmospheres) is a DVD with 91,520 stellar model atmospheres representing a 5D grid of modified ATLAS9 atmospheres; the purpose of the modifications was to include different treatments of convection and higher vertical resolution. In addition, for every model fluxes are provided and color indices for 14 different photometric systems. Because the model grid contained gaps due to non-converging models, we developed and applied a set of 4D interpolation routines to complete the grid. All the data, which will continuously be updated, can be found on the NEMO homepage (http://ams.astro.univie.ac.at/nemo/) and are available via DVD.
