Abstract
The launch of the Kepler mission has produced a huge increase in the number of stars that can be studied using asteroseismology. Hundreds of main-sequence and sub-giant stars now have accurately determined oscillation parameters, which allow us to characterize their properties to unprecedented levels of precision. Taking advantage of the extremely precise data from Kepler and available multi-band photometry of the field, we combine results from the InfraRed Flux Method with stellar parameters determined from asteroseismology to estimate distances for ~500 solar-type stars. We compare the distances with those available from Hipparcos data, and discuss the potential of the method and its implications for galactic chemical evolution models.
