Asteroseismic Tests of Stellar Models

Stellar models form one of the pillars of astrophysics, impacting our understanding of everything from planets to galaxies. While these models do well for stars similar to the sun, it has become clear that they are inconsistent with measurements of evolved stars. I will discuss recent efforts using a combination of asteroseismology and the APOGEE spectroscopic survey to identify discrepancies and improve the physics of stellar models. I will begin with a discussion of metallicity dependent temperature offsets between models and data, and how to resolve them with metallicity dependent parameterizations of convection. I will then discuss how these models and data sets can be used to improve our understanding of rotation, mixing, and chemical evolution. Finally, I will discuss the prospects for further improvement to our understanding of stellar physics with the upcoming TESS mission.
