cds-question@unistra.frvariable-starsdwarf-galaxiesphotometryvisible-astronomygalaxieslocal-groupTo identify long-period variable (LPV) stars in IC 10-the nearest starburst galaxy of the Local Group-we conducted an optical monitoring survey using the 2.5m Isaac Newton Telescope with the wide-field camera (WFC) in the i band and V band from 2015 to 2017. We created a photometric catalog for 53,579 stars within the area of CCD4 of WFC (~0.07deg^2^ corresponding to 13.5kpc^2^ at the distance of IC 10), of which we classified 536 and 380 stars as LPV candidates, mostly asymptotic giant branch (AGBs) stars and red supergiants, within CCD4 and two half-light radii of IC 10, respectively. By comparing our output catalog to the catalogs from Pan-STARRS, Spitzer Space Telescope, Hubble Space Telescope (HST), and carbon stars from the Canada- France-Hawai'i Telescope survey, we determined the success of our detection method. We recovered ~73% of Spitzer's sources in our catalog and demonstrated that our survey successfully identified 43% of the variable stars found with Spitzer, and also retrieved 40% of the extremely dusty AGB stars among the Spitzer variables. In addition, we successfully identified ~70% of HST variables in our catalog. Furthermore, we found all the confirmed LPVs that Gaia DR3 detected in IC 10 among our identified LPVs. This paper is the first in a series on IC 10, presenting the variable star survey methodology and the photometric catalog, available to the public through the Centre de Donnees Astronomiques de Strasbourg.2025AJ....170...54Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/170/54CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/355 : Gaia DR3 Part 1.
