Updated and Expanded OPAL Equation‐of‐State Tables: Implications for Helioseismology
Open accessAbstract
We are in the process of updating and extending the OPAL equation-of-state (EOS) and opacity data to include low-mass stars. The EOS part of that effort now is complete, and the results are described herein. The new data cover main-sequence stars having mass ≥0.1 M ☉ . As a result of the more extreme matter conditions encountered with low-mass stars, we have added new physics. The electrons are now treated as relativistic, and we have improved our treatment of molecules. We also consider the implications of the new results for helioseismology.

“The uncertainty essentially reflects the difference between the MHD (Mihalas, Däppen & Hummer 1988) and OPAL (Rogers & Nayfonov 2002) equation-of-state, but there is also a minor dependence on the assumed metallicity of the reference solar model for the inversion (Trampedach, Däppen & Baturin 2006).”

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.
