  • This project began as a search for triple-mode pulsating red giants (PRGs) among known double-mode PRGs,, using AAVSO visual data. It then expanded to include a check on the reality and significance of some double-mode PRGs. We identified several "double-mode" PRGs in which one of the periods might simply be an alias of the other. We also comment on the possibility that the additional periods might be harmonics, rather than overtones. As for the triple-mode pulsators: in our sample, we find no… CONTINUE READING
