The Kepler LEGACY project: the best and brightest of the main-sequence solar-like oscillators

The nominal Kepler mission produced a true revolution in our understanding of solar-like oscillations in main-sequence stars. From the hundreds of these stars where excess power in the light curve was detected, we selected those with more than one year of short-cadence observations to use as a benchmark set. These 66 unique stars comprise the Kepler LEGACY sample, and the aim of this project is to provide the most accurate set of stellar properties possible using 7 different methods of asteroseismic fitting. In this talk I present the results of this effort and stellar properties for these benchmark stars that can be used by the community for a number of different applications, and comment on the actual precisions in asteroseismically derived parameters and their accuracy when independent constrains are available. The results of this comparison have important implications for large scale surveys where automated analysis methods are mandatory, such as TESS and PLATO.
