RESUMEN. Las opacidades medias de Rosseland calculadas con el programa OPAL se comparan con los resultados de Los Alamos, encontrando diferencias de factores de tres. Estas diferencias se atribuyen a los adelantos, tanto en Ia ecuaci6n de estado como en la fisica at6mica, del programa OPAL. Ma's aiin, investigaciones recientes han demostrado que las nuevas opacidades de OPAL eliminan las discrepancias entre las observaciones y los modelos estelares. ABSTRACT. The Rosseland mean opacities computed using the OPAL codes show significant differences when compared to the Los Alamos results. The differences have been traced to improvements in both the equation of state and atomic physics in the OPAL code. Furthermore, recent work suggests that the OPAL opacities considerably improve the agreement between observations and stellar models. Key words: OPACITIES - SUN: INTEMOR - STARS: VARIABLE
