Scientific paper

Results are presented on a study of the short period variable stars in the
dwarf irregular galaxy NGC6822. We observed an almost uniformely populated
classical instability strip from the Horizontal Branch up to the Classical
Cepheids region. The main goal we achieved from the analysis of the faint
sample is the first detection of RR Lyrae stars in this galaxy.
