Abstract

Standard stellar models for η Boo fail to reproduce the newly observed low frequency p-modes from space and the high frequency p-modes observed from the ground, simultaneously. This discrepancy can be removed by including turbulence in the modeling of the outer layers of η Boo. We include turbulence by applying the effects of turbulent pressure and turbulent kinetic energy -- extracted from a hydrodynamical 3D convection simulation for the Sun -- at the correct depth in the 1D models of η Boo.
