Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Asteroseismology has been extremely successful in determining the properties of stars in different evolutionary stages with a remarkable level of precision. However, to fully exploit its potential, robust methods for estimating stellar parameters are required and independent verification of the results is needed. In this talk, I present a new technique developed to obtain stellar properties by coupling asteroseismic analysis with the infrared flux method. Using two global seismic observables and multi‐band photometry, the technique determines masses, radii, effective temperatures, bolometric fluxes, and thus distances for field stars in a self‐consistent manner. Applying our method to a sample of solar‐like oscillators in the <italic>Kepler</italic> field that have accurate Hipparcos parallaxes, we find agreement in our distance determinations to better than 5 %. Comparison with measurements of spectroscopic effective temperatures and interferometric radii also validate our results, and show that our technique can be applied to stars evolved beyond the main‐sequence phase.
