Descripción
Over the past two decades, helioseismology has revolutionized our
understanding of the interior structure and dynamics of the Sun.
Asteroseismology will soon place this knowledge into a broader context
by providing structural data for hundreds of Sun-like stars. Solar-like
oscillations have already been detected from the ground in several
stars, and NASA's Kepler mission is poised to unleash a flood of stellar
pulsation data. Deriving reliable asteroseismic information from these
observations demands a significant improvement in our analysis methods.
In this paper, we report the initial results of our efforts to develop
an objective stellar model-fitting pipeline for asteroseismic data. The
cornerstone of our automated approach is an optimization method using a
parallel genetic algorithm. We describe the details of the pipeline and
we present the initial application to Sun-as-a-star data, yielding an
optimal model that accurately reproduces the known solar properties.
