Abstract
There is no one observable that is sensitive to age and age alone. However, some combinations of parameters such as large frequency separation and small frequency separation are more sensitive to age. The age can be better constrained by comparing these observables with parameters extracted from stellar models. Extracting ages from stellar models is an optimization problem that seeks the initial stellar conditions and amount of time elapsed that gives the best fit to a measured set of observables.
