Description

Recently the Corot and Kepler satellite missions have discovered sun-like oscillations in more than a few tens of thousands of stars. This large amount of data has the potential of revolutionizing our understanding of the internal physics of stars in the main-sequence, sub-giant and red-giant phases. Equally the forthcoming stellar planetary mission Plato will extend the potential for discoveries in stellar astrophysics even further.
This study will focus on the computation of the evolution models and the spectra of oscillations of pulasational white dwarf stars at critical stages of their evolution along their characteristic cooling curves. These models will be done using high precision numerical codes of stellar evolution and stellar oscillations. Equally when possible, an analytical model is to be used in order to interpret the theoretical data sets and check the theoretical predictions against real astronomical data. Additionally, predictions for the forthcoming Plato mission are to be performed.
