Abstract

The interiors of stars are not directly accessible for scientific experiment. This is problematic, because the life of stars, and by implication of galaxies in the Universe, is directed by the physical processes acting in their core regions.  How do stars rotate internally? How do the products of nucleosynthesis mix inside stars?  Do stars have an internal magnetic field?  Thanks to the recent research domain of asteroseismology we can now start to answer these questions for various types of stars through interpretation of their oscillation frequencies. During the talk, we explain the basic principles of asteroseismology and we illustrate the immense advantage of having long-term uninterrupted high-precision data from space missions.  We review the current status of the probing of stellar physics in general, and of the measurement of internal rotation and angular momentum in particular. We end with future prospects by highlighting the potential of asteroseismology as tool in the study of galactic archeology and of exoplanetary systems.
