Fig. Normalized, cumulative, linear work integrals for 4.5 solar masses model, lying 300K to the red of the fundamental mode blue edge. Red line shows the gas(+radiation) pressure work integral, blue line shows the eddy-viscous work integral and green line shows the turbulent pressure work integral. Work integrals are scaled by kinetic energy of the fundamental mode. Pulsations are driven in a temperature range in which work integral grows (as temperature gets lower). [post script]
