The chemi-ionization processes in atom - Rydberg atom collisions. as well as the corresponding chemi-recombination processes. are considered as factors of influence on the atom exited-state populations in weakly ionized layers of stellar atmospheres. The presented results are related to the photospheres of the Sun and some M red dwarfs. https://www.bekindtopets.com/save-now-Aqua-Pure-3MFF101-Full-Flow-Drinking-Water-System-Replacement-Cartridge-flash-choice/
