Abstract

Eclipsing binaries (EBs) are a key which opens the door to a chamber of knowledge. Thus the research of EBs in open clusters (OCs) is very promising. However, only several lists of eclipsing binaries known in OCs have been published, the last one almost three decades ago. We introduce a new catalogue of EBs in the field of open clusters. In addition we establish a new program for skilled amateur astronomers who are able to produce a significant amount of photometric data of sufficient accuracy. Photometry as well as spectroscopy of selected EBs in OCs will be used to determine stellar parameters of components in binaries and cluster parameters.
