Resonant Mode Coupling in δ Scuti Stars
Resonant Mode Coupling in δ Scuti Stars
Abstract Delta Scuti ( δ Sct) variables are intermediate-mass stars that lie at the intersection of the main sequence and the instability strip on the Hertzsprung–Russell diagram. Various lines of evidence indicate that nonlinear mode interactions shape their oscillation spectra, including the particularly compelling detection of resonantly interacting mode triplets …
