Description
We use a time-dependent model of turbulent convection which includes turbulent pressure, turbulent diffusion and turbulent viscosity to study stellar pulsations in young brown dwarfs recently proposed by Palla and Baraffe (2005). We find that turbulent pressure dominates in driving the oscillations with growth rates much higher than frozen-in approximation.
