cds-question@unistra.frgalaxiesvariable-starsccd-photometryWe report on the discovery of a Cepheid population in the Sculptor Group spiral galaxy NGC 247 for the first time. On the basis of wide-field images collected in photometric surveys in V and I bands that were conducted with three different telescopes and cameras, 23 Cepheid variables were discovered with periods ranging from 17 to 131 days.2008AJ....136.1770Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/136/1770CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/132/2556 : Cepheids in NGC 55 (Pietrzynski+, 2006)J/A+A/485/41 : NGC 55 VLT spectroscopy of blue massive stars (Castro+, 2008)J/ApJ/672/266 : NGC 55 Cepheids JK magnitudes (Gieren+, 2008)J/AJ/123/789 : NGC 300 Cepheid variables (Pietrzynski+, 2002)J/MNRAS/350/679 : BV photometry of NGC 300 variables (Mennickent+, 2004)J/AJ/128/2815 : NGC 6822 Cepheid variables (Pietrzynski+, 2004)J/A+A/450/873 : NGC 6822 bright variables VI phot.
