Abstract:
Using one-dimensional radiation-hydrodynamics simulations a model of
the outer atmosphere of Alpha Tau is created. The reaction of the
model to acoustic waves is explored. It is found that high frequency
waves are radiatively damped out in the photosphere. The lower
frequency waves above the Hydrodynamic acoustic cutoff frequency do
produce some chromospheric heating.
