From protostar to pre-main sequence pulsators: PLATO and the quest for the classification of young stars

The advent of space photometry has brought immense opportunities to the field of asteroseismology. This superb data has led to novel methodologies to infer information about pulsating stars and has proven especially useful for the characterisation of exoplanet host stars. Recent discoveries have spiked interest in the discovery and characterisation of young planets. For this to be successful, however, it is inevitable to perform this in-depth asteroseismic analysis also for pre-main sequence stars: A group of stars, for which the stellar modelling usually suffers from unrealistic assumptions about their initial state.
We will present the first pulsational analysis of pre-main sequence models originating from accreting protostars as a more realistic initial scenario. With a suitable observational strategy, PLATO could be the last puzzle stone to skyrocket pre-main sequence asteroseismology and, hence, bring the characterization of the youngest exoplanets‘ host stars to the next level.
