| Abstract: |
John Bahcall played a central role in modern astronomy. His numerous contributions to stellar astrophysics will be reviewed, with a focus on studies of the Sun. I will argue that the current solar abundance controversy has many of the same elements as the solar neutrino problem that John played a decisive role in solving. The combination of helioseismology and interiors theory can be used to predict the absolute abundances in the Sun. There is a conflict between this abundance scale and the one predicted by recent stellar atmospheres calculations, indicating that there are unrecognized issues in one or both theories. Finally, the resolution of this problem will have broad consequences which will be discussed. |
