| Abstract: | Chemical composition is a good tracer of the hydrodynamical processes that occur in stars as they often lead to mixing and
particle transport. By comparing abundances predicted by models and those observed in stars we can infer some constraints
on those mixing processes. As pulsations in the stars are often very sensitive to chemical composition, we can use asteroseismology
to probe the internal chemical composition of stars where no direct observations are possible. In this paper I focus on main
sequence stars Am, λ Bootis, and HgMn stars and discuss what we can learn of mixing processes in these stars from seismology. |
