Uncertainties in models of stellar structure and evolution

TL;DR

This paper reviews the current state of uncertainties in stellar structure and evolution models, highlighting key issues discussed during a workshop and summarizing the latest understanding as of July 2013.

Contribution

It provides a comprehensive overview of the uncertainties in stellar modeling, based on expert discussions and a compiled table of model uncertainties.

Findings

Identified key physical uncertainties affecting stellar models.

Compiled a state-of-the-art table of model uncertainties as of July 2013.

Summarized expert opinions from a dedicated workshop.

Abstract

Numerous physical aspects of stellar physics have been presented in Ses- sion 2 and the underlying uncertainties have been tentatively assessed. We try here to highlight some specific points raised after the talks and during the general discus- sion at the end of the session and eventually at the end of the workshop. A table of model uncertainties is then drawn with the help of the participants in order to give the state of the art in stellar modeling uncertainties as of July 2013.
