| Abstract: | Advances in stellar interior modeling are being driven by new data from large-scale surveys and high-precision photometric
and spectroscopic observations. Here we focus on single stars in normal evolutionary phases; we will not discuss the many
advances in modeling star formation, interacting binaries, supernovae, or neutron stars. We review briefly: (1) updates to
input physics of stellar models; (2) progress in two and three-dimensional evolution and hydrodynamic models; (3) insights
from oscillation data used to infer stellar interior structure and validate model predictions (asteroseismology). We close
by highlighting a few outstanding problems, e.g., the driving mechanisms for hybrid γ Dor/δ Sct star pulsations, the cause of giant eruptions seen in luminous blue variables such as η Car and P Cyg, and the solar abundance problem. |
