Résumé
A new and extensive grid of model atmospheres is under construction with the MARCS computer program. The models are spherically symmetric, in LTE and with mixing-length convection. They include a detailed treatment of opacities with opacity sampling. The grid Covers the range from T-eff = 2500 to 8000 K, log g = -1.0 to 5.0 (cgs), masses,from, 0.5,to 30Mcircle dot, and metallicities [A/H] from -6.0 to +1.0.
