Abstract
The single most important parameter which determines the evolution of a star is its mass. Detached eclipsing binaries offer the possibility to determine accurate masses and radii for their components. By studying such systems in open and globular clusters it is possible to determine cluster ages to higher precision than by “traditional” methods, such as main-sequence fitting. We have initiated a programme to study detached eclipsing binaries in old open and globular clusters and determine their masses and radii. This allows direct comparisons with models in the mass, radius plane thereby avoiding the troublesome conversion between model (bolometric luminosity, temperature) and observed (color, apparent luminosity) quantities.
