Stability and Dynamics of Three-mode Coupling in δ Scuti Stars

Recent observations of δ Scuti stars find evidence of nonlinear three-mode coupling in their oscillation spectra. There are two types of three-mode coupling likely to be important in δ Scuti stars: (i) direct coupling, in which two linearly unstable modes (driven by the κ -mechanism) excite a linear...
