Opacities for the solar radiative interior
Abstract
Opacities for the solar radiative interior are computed and compared to previous calculations. A significant enhancement of the Rosseland mean opacity near the bottom of the convention zone is reported when compared to the Los Alamos Astrophysical Opacity Library (LAOL). The discrepancy is attributed mainly to the equation of state. Absorption processes are investigated and their uncertainties estimated. The new results using the OPAL opacity code are given in tabular form for the Ross-Aller, Aller, Grevesse, and Anders-Grevesse solar mixtures. Variations in the opacity due to the different chemical compositions are found to be comparable in size to those between the LAOL and OPAL codes. The plasma conditions in the tables cover the parameter range relevant for standard solar models.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
