Scientific paper

Standard stellar models for η Boo fail to reproduce the observed low frequency p-modes from space and the high frequency p-modes observed from ground, simultaneously. This discrepancy can be mitigated by including turbulence in the modeling of the outer layers of η Boo. We present new results of our full 3D turbulent convection simulation of η Boo's outer layers. With these simulations we are able to answer the question whether the discrepancy between models and observations can be fully attributed to the effects of turbulence.
This research was supported by NASA grant NAG5-13299, and in part by the NASA EOS/IDS program.
