Scientific paper

We present an update of our on-going effort to improve the precision of white dwarf cosmochronology via careful analyses of white dwarf photometry in open clusters. To improve the precision of white dwarf and main sequence age analysis, we are developing a new interpretative scheme using a Bayesian statistical approach that matches observations to simulated stellar clusters. Here we present our first tests of the Bayesian approach with simulated stellar clusters with ages of 1, 2, and 4 billion years.
