Araucaria: NGC 6822 bright variables VI phot.
Listed in IVOA Registry (Virtual Observatory)
We have performed a search for variable stars in the dwarf irregular galaxy NGC 6822 using wide-field multi-epoch VI photometry down to a limiting magnitude of ~22.
Description
A part from the Cepheid variables in this galaxy already reported in an earlier paper by Pietrzynski et al. (2004AJ....128.2815P), we have found 1019 "non-periodic" variable stars, 50 periodically variable stars with periods ranging from 0.12 to 66 days and 146 probably periodic variables.
Twelve of these stars are eclipsing binaries and fifteen are likely new, low-amplitude Cepheids.
