Period doubling spin-off PD led to the discovery of a plethora of other dynamical phenomena: - high-order resonances (9:2) Szabó, Kolláth, Molnár et al. 2010, MNRAS 409, 1244 - presence of high radial overtones (strange modes) Kolláth, Molnár, Szabó 2011, MNRAS, 414, 1111 - presence of other radial modes (1 st and 2 nd overtones) in Blazhko stars Molnár, Kolláth, Szabó et al. ApJL, 2012, 757, 13 - even low-dimensional chaos Plachy, Molnár, Kolláth 2013, MNRAS 433, 3590 - new explanation of the Blazhko effect Buchler & Kolláth ApJ 2011, 731, 24
A new explanation for the Blazhko effect Buchler & Kolláth ApJL, 731, 24, 2011 Irregular amplitude modulations naturally result from the nonlinear resonant mode coupling between the fundamental mode and the 9 th overtone using amplitude equations.
