Query: The Power of Principled Bayesian Methods in the Study of Stellar
  Evolution   It takes years of effort employing the best telescopes and instruments to
obtain high-quality stellar photometry, astrometry, and spectroscopy. Stellar
evolution models contain the experience of lifetimes of theoretical
calculations and testing. Yet most astronomers fit these valuable models to
these precious datasets by eye. We show that a principled Bayesian approach to
fitting models to stellar data yields substantially more information over a
range of stellar astrophysics. We highlight advances in determining the ages of
star clusters, mass ratios of binary stars, limitations in the accuracy of
stellar models, post-main-sequence mass loss, and the ages of individual white
dwarfs. We also outline a number of unsolved problems that would benefit from
principled Bayesian analyses.
