Abstract

PENA, J. H. et al. uvby - β Photoelectric Photometry of the Open Clusters NGC 6811 and NGC 6830. Rev. mex. astron. astrofis [online]. 2011, vol.47, n.2, pp. 309-321. ISSN 0185-1101.

From uvby -β photometry of the open clusters NGC 6811 (75 stars), and NGC 6830 (19 stars) we were able to determine membership of the stars to each cluster, and fix the age and reddening for each. Since several short period stars have recently been found, we have carried out a study of these variables.

Keywords : open clusters and associations [individual (NGC 6811, NGC 6830)]; techniques [photometric].
