Solar-like oscillations in subgiant and red-giant stars: mixed modes

摘要: Thanks to significant improvements in high-resolution spectrographs and the launch of dedicated space missions MOST, CoRoT Kepler, number subgiants red-giant stars with detected oscillations has increased significantly over last decade. The amount detail that can now be resolved oscillation patterns does allow for in-depth investigations internal structures these stars. One phenomenon plays an important role such studies are mixed modes. These modes carry information inner radiative region as well from convective outer part star allowing probe different depths Here, we describe highlight some recent results obtained using observed
