The potential of space observations for pulsating pre-main sequence stars
Konstanze Zwintz (Institute for Astro- and Particle Physics, University of Innsbruck)

Asteroseismology of pre-main sequence (pre-MS) stars has the power to constrain the interior structure of stars in their earliest evolutionary phases and, hence, allows to address some of the yet open questions of early stellar evolution. Depending on their masses, pre-MS stars can show four different types of pulsations: (i) g-mode Slowly Pulsating B star pulsations, (ii) delta Scuti type p-mode pulsations, (iii) gamma Doradus like g-mode pulsations and (iv) stochastic solar-like oscillations. Within the past ~15 years, several dozens of pre-MS SPB, delta Scuti and gamma Doradus type pulsators were investigated using data obtained from ground and from space (i.e., using MOST, CoRoT and recently K2). Pre-MS solar-like oscillators are theoreticall predicted, but are still lacking the first observational detection. I will discuss the current observational status of pre-MS pulsators and the potential of TESS observations which can significantly advance the field of pre-MS asteroseismology in particular for the coolest young objects.
