The main functionality of FOAM is to perform forwards asteroseismic modelling of gravity modes via a modelling pipeline. An example of a science case for which this pipeline was used is the modelling of the slowly pulsating B-type star KIC7760680 by Michielsen et al. (2021). The paper used an early version of the pipeline without optimising the rotation for each model individually, but a lot of its functionality was already used in this paper. Numerous updates in both performance and functionality have been included since and are employed in the modelling of the B-type binary KIC4930889 by Michielsen et al. (2023).

Modelling pipeline

The setup is made for the purpose of asteroseismic gravity mode modelling. It’s functionality allows for:

• Modelling of the observations with multiple different computed grids.
• Use of different merit functions (reduced chi-squared and Mahalanobis Distance are currently implemented).
• Use of multiple sets of observables. Asteroseismic (periods, period spacings, frequencies) but also others (logg, logTeff, logL, …) can be added in the merit function.
• Use of multiple different methods to construct theoretical pulsation patterns to match the observed pattern. See pipeline configuration for a more detailed and complete list of the options and choices.
