TL;DR: In this article, the authors used previously published asteroseismic and spectroscopic data sets to provide a uniform analysis of 42 solar-type Kepler targets from AMP and found that fitting the individual frequencies typically doubled the precision of the asteroseismsic radius, mass, and age compared to grid-based modeling of the global oscillation properties, and improved the radius and mass by about a factor of three over empirical scaling relations.

TL;DR: In this article, preliminary asteroseismic results from Kepler on three G-type stars are presented, made at one-minute cadence during the first 33.5d of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars: about 20 modes of oscillation may be clearly distinguished in each star.
