Towards the understanding of the deepest layers of solar-like pulsators
Abstract
The main goal of my current research concerns the asteroseismic study of small convective cores of solar-like pulsators which are present in stars slightly more massive than our Sun. The characterization of stellar cores plays an important role in the understanding of the evolution of stars, and can have direct consequences for stellar age determinations.
The presence of a convective core leaves a signature on the oscillation frequencies that can in principle be detected by combining them in particular ways, i.e., by building adequate asteroseismic diagnostic tools. In this poster we will illustrate what kind of information may be inferred about stellar cores when analysing the oscillation spectrum of the star. To perform this work we use a grid of stellar models and corresponding oscillation frequencies. We show that our analysis can be applied to real stars, as long as their oscillation frequencies are derived with enough precision, such as in stars observed by the Kepler satellite.
