Abstract

Stellar seismic inversions have proved to be a powerful technique for probing the internal structure of stars, and paving the way for a better understanding of the underlying physics by revealing some of the shortcomings in current stellar models. In this lecture, we provide an introduction to this topic by explaining kernel-based inversion techniques. Specifically, we explain how various kernels are obtained from the pulsation equations, and describe inversion techniques such as the Regularised Least-Squares (RLS) and Optimally Localised Averages (OLA) methods.

Acknowledgements

I would like to thank the organisers of this Summer School for giving me the opportunity to give this lecture on inversions. Furthermore, I thank M.J. Thompson for introducing me to inversions, as well as S. Basu and G. Buldgen for many discussions on the topic.
