Radiative atomic Rosseland mean opacity tables

Rogers, Forrest J., Iglesias, Carlos A.·1992·The Astrophysical Journal Supplement Series

Abstract

New radiative Rosseland mean opacity tables calculated with the OPAL code are presented. Extensive results are given for the recent mixture of Anders-Grevesse (1989) which allow accurate interpolation in temperature, density, hydrogen mass fraction, and metal mass fraction. The range of the constant R and temperature are such as to cover typical stellar conditions from the interior through the envelope and the hotter atmospheres. For comparison purposes, some opacity table for the Ross-Aller and Cox-Tabor metal abundances are presented. Although in many regions the OPAL opacities are similar to previous work, significant differences are reported. For example, factors of 2-3 opacity enhancements are found in stellar envelope conditions.

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.
