Abstract: An investigation is conducted as to whether strong shocks produced in time-dependent stochastic wave models can explain the formation of the He I 10830 line in a cool giant star like Arcturus. The exploratory research is based on the work of Cuntz (1987) who found that stochastic waves lead to overtaking and merging of shocks producing occasionally very strong shocks with temperatures larger than 40,000 K in the postshock regions.
