  A simple solar scaling relation for estimating the ages of main-sequence
stars from asteroseismic and spectroscopic data is developed. New seismic
scaling relations for estimating mass and radius are presented as well,
including a purely seismic radius scaling relation (i.e., no dependence on
temperature). The relations show substantial improvement over the classical
scaling relations and perform similarly well to grid-based modeling.
