Abstract

The CoRoT and Kepler space missions, while still ongoing, already revolutionised our view on stellar pulsation. In this talk, we illustrate how the immense advantage of having long-term uninterrupted data from space with a factor 100 better precision compared to data from the ground implies large progress in the tuning of stellar physics. In particular, we focus on the cases where gravity-mode oscillations were detected and allowed modelling of the near-core regions in stars. We end by highlighting future prospects based on the continuing data gathering by both missions.
