Query: Testing stellar evolution with asteroseismic inversions of a main
  sequence star harboring a small convective core   The goal of stellar evolution theory is to predict the structure of stars
throughout their lifetimes. Usually, these predictions can be assessed only
indirectly, for example by comparing predicted and observed effective
temperatures and luminosities. Thanks now to asteroseismology, which can reveal
the internal structure of stars, it becomes possible to compare the predictions
from stellar evolution theory to actual stellar structures. In this work, we
present an inverse analysis of the oscillation data from the solar-type star
KIC 6225718, which was observed by the \emph{Kepler} space observatory during
its nominal mission. As its mass is about 20% greater than solar, this star is
predicted to transport energy by convection in its nuclear-burning core. We
find significant differences between the predicted and actual structure of the
star in the radiative interior near to the convective core. In particular, the
predicted sound speed is higher than observed in the deep interior of the star,
and too low at a fractional radius of 0.25 and beyond. The cause of these
discrepancies is unknown, and is not remedied by known physics in the form of
convective overshooting or elemental diffusion.
