Advances in stellar interiors physics and evolution have been made possible by asteroseismology, the study of stars by the observation of their natural, resonant oscillations. In particular, asteroseismology has vastly benefited the study of solar-type and red-giant stars, which exhibit convection-driven, solar-like oscillations. The future looks bright, with NASA’s TESS and ESA’s PLATO space missions promising to raise the number of known solar-like oscillators by one order of magnitude. The information contained in stellar oscillations allows fundamental stellar parameters (radius, mass, and age) to be precisely determined. As a result, asteroseismology is having a profound impact on modern astrophysics, notably in the fields of exoplanetary science and Galactic archaeology, which rely on precise stellar parameters. In this talk, I will introduce the field of asteroseismology, explaining how this powerful technique is being used to elucidate the dynamics and evolution of planetary systems, as well as to enable the time-resolved investigation of Galactic assembly.
