Evidence of amplitude modulation due to resonant mode coupling in the<i>δ</i>Scuti star KIC 5892969
A study of the star KIC5892969 observed by the Kepler satellite is presented. Its three highest amplitude modes present a strong amplitude modulation. The aim of this work is to investigate amplitude variations in this star and their possible cause. Using the 4 years-long observations available, we obtained the frequency …
