Pinpointing isochrones in clusters .
Abstract
Detached eclipsing binaries allow the determination of accurate stellar masses and radii. Here we present the first results of a programme which aims at using such systems for the determination of accurate stellar parameters in open star clusters and discuss this in relation to the study of pulsating stars. As an example we show results for a detached eclipsing system in the old open cluster NGC 188 and briefly discuss the two intermediate age open clusters NGC 1817 and NGC 2506 which both contains pulsating stars and detached eclipsing binaries.
