cds-question@unistra.fratomic-physicsstellar-atmospheric-opacityThe Rosseland mean free-free Gaunt factor of the dense high-temperature stellar plasma is calculated, based on both the accurate relativistic cross section and Sommerfeld's exact nonrelativistic cross section. A wide range of electron degeneracy is accurately taken into account. Comparison of the resulting free-free opacity with the electron conduction opacity is made.1991ApJ...382..636Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/382/636CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/63/661 : Relativistic Free-Free Gaunt Factor (Nakagawa+ 1987)J/ApJS/74/291 : Relativistic Free-Free Gaunt Factor.
