Stellar core collapse - Numerical model and infall epoch
Abstract
The core infall stage of the final evolution of a ten solar mass star is studied using an accurate and detailed numerical model. The features of the model include a realistic initial model and equation of state, general relativistic hydrodynamics, independent treatment of neutrino pairs, multigroup flux-limited diffusion, direct solution of the electron scattering and thermal production terms, evaluation of exact neutrino interaction expressions, and a consistent treatment of the effects of matter compression and expansion on the neutrinos, including the transparent cutoff. Deleptonization occuring during the collapse is carefully examined, and a detailed comparison is made between the numerical results for the collapse and shock propagation phases and the conceptual framework.

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.
