AE Solver is a computational framework made to estimate the degree of (resonant) non-linear coupling among oscillation modes in oscillating stars. It is split up in different sub-packages to increase modularity (and ease of future extension).

The exemplary/proof-of-concept science case that makes use of this computational framework is described in detail in Van Beeck et al. (2024), and concerns resonant non-linear coupling among gravito-inertial modes (GIMs) in stellar models typical of slowly pulsating B stars.
Using such couplings we showed that one of the non-linear observables computed by this framework – the amplitude ratios of (non-linearly coupled) GIMs – can aid asteroseismic modeling efforts by incorporation of the (resonant) combination frequencies. We refer the interested reader to section 5 of Van Beeck et al. (2024) for more details on the potential impact non-linear observables may have in asteroseismic modeling.
