Crivellari Física, Astronomía y Matemáticas plasmas equation of state Partition function stellar atmospheres The partition function for atoms in a gas with partial ionization is obtained by assuming that the internal and atomic linear energy densitiesare equal, and considering that the kinetic energy per degree of freedom is sufficient to ionize the upper levels of the atoms, and, at the sametime, approximating the sum by an integral, which we solve using the mean value theorem for integrals. The resulting function reproducesthe behavior of the partition function in the region of validity of perfect gases; it is also analytic and compact. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57064106 https://www.redalyc.org/journal/570/57064106/ https://www.redalyc.org/journal/570/57064106/html/ https://www.redalyc.org/journal/570/57064106/57064106.epub https://www.redalyc.org/journal/570/57064106/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
