Binaries as precious tools for stellar evolution and asteroseismology

Abstract

Eclipsing double-lined binaries had a fundamental role in laying the foundations of stellar astro-physics and are still today an invaluable tool, as they provide an independent, purely geometrical, and accurate determination of the stellar masses and radii (often with uncertainties lower than 1%). This paper briefly reviews some important contributions to the field of stellar structure and to the more recent one of asteroseismology.
