Delta Scuti 𝛿-Scuti are a type of variable star that show detectable brightness fluctuations obeying a period-luminosity relationship. The brightness fluctuations are caused by unstable excited mode oscillations (fluid waves) The Kepler space telescope has observed around 1000 𝛿-Scuti stars, over half of which exhibit large amplitude variations and evidence for nonlinear mode coupling We demonstrated that this type of nonlinear coupling occurs often. Scuti models and can be utilized to explain these observations that contradict the linear theory. We utilized a second nonlinear mechanism to stabilize the excited waves and showed that we can study the evolution of these modes through time.
