[69.12] Asteroseismic Diagnostics of Stellar Convective Cores

A. Mazumdar, B. L. Collier, S. Basu, P. Demarque (Yale University)

The extent of the central convective region is one of the crucial factors that govern the structure and evolution of massive stars. It has been suggested that observations of seismic waves that penetrate the deepest layers of a star might be used to estimate the size of such convective cores. This would allow a rigorous test of the current theories of convection and stellar evolution. We investigate whether suitable diagnostics can be constructed from the frequencies of low degree modes of oscillation which are sensitive to the size and evolution of the stellar core.
