The XXII Canary Islands Winter School of Astrophysics (WS), organized by the Instituto de Astrofisica de Canarias (IAC), focuses on the new advances and challenges that Asteroseismology provides in the domains of stellar structure, dynamics and evolution. The WS welcomes a maximum of 60 PhD students and young Post-Docs, and provides each year a unique opportunity for the participants to broaden their knowledge in a key field of Astronomy.


Scientific Rationale

When oscillations of the Sun were first discovered a new era of science began. The observed frequencies could be used to probe deep into the stellar interior, the only measurements that could possibly pierce the stellar surface. Today “helioseismology” has been responsible for some of our most deepest understanding of the Sun: we know the radial and longitudinal rotation profile of the interior, we have measured the depth of the outer convection zone, it has helped solve the so-called “neutrino problem” when the observations and theory predicted a much hotter central temperature than the observed neutrinos predicted. Today these seismic observations are not only available in much higher quality, but they are also available for hundreds of other stars. In the last few years many space missions (CoRoT and Kepler) have produced these data of exquisite quality and for the first time we are in a position to study the Sun in the context of other stars, measure the fundamental parameters of single field stars to less than 2%, learn about diffusion processes and the effects of rotation on the stellar structure, and test opacities and equations of state in extreme conditions.
The key objectives of this Winter School are to provide young scientists with knowledge and understanding of observation, instrumentation, theory, modelling and computing for Asteroseismology.
