- Аннотация: It is shown that for the luminescence of hydrogen in shock fronts in the atmospheres of stars in latespectral classes, the level populations of the hydrogen atoms are determined by the entire prehistory ofthe process, beginning with heating in the shock front, as well as by the instantaneous electron tempera-ture and density. Ionization from excited states with principal quantum numbers 2<k<6 plays animportant role. The role of highly excited states of hydrogen atoms as they are ionized in shock frontsunder the conditions of stellar atmospheres is clarified. The contribution of states with k > 10 to theionization rate can substantially exceed the rate of ionization from the ground state.
