| 英文摘要 | The controversies about the excitation mechanism for cool variables are reviewed: (1) Most people believe that gamma Doradus stars are excited by so called convective blocking. Our researches show that the excitation of gamma Doradus has no difference from that of delta Scuti. They are two subgroups of a broader type of delta Stuti-gamma Doradus stars: delta Scuti is the p-mode subgroup, while gamma Doradus is the g-mode subgroup. (2) Most people believe that the Solar- and Solar-like oscillations of stars are damped by convection, and they are excited by so called stochastic effects of turbulence. Our researches show that convection is not solely a damping mechanism for stellar oscillations, otherwise it is not able to explain the excitation of Mira and Mira-like stars. It can be repeated not only the delta Scuti and gamma Doradus strip, but also the characteristics of Solar-like and Mira-like oscillations, respectively, for the low- and high- luminosity red stars by using our non-local and time-dependent theory of convection. |
