The PB05 study presents results of a non-adiabatic linear stability analysis showing that young brown dwarfs should become pulsationally unstable during the deuterium burning phase of their evolution.enBrown dwarfsVery low mass starsPulsation equationsPerturbation equationsWork integralsViscosityTurbulent pressureFree parametersThesisUniversity of the Western Cape
