J/A+A/493/1075 JKs photometry of C stars in 2 nearby galaxies (Battinelli+ 2009)

Assessment of the near infrared identification of carbon stars. II. The local group galaxies IC 1613 and NGC 3109. Battinelli P., Demers S. <Astron. Astrophys., 493, 1075-1080 (2009)> =2009A&A...493.1075B
ADC_Keywords: Stars, carbon ; Photometry, infrared Keywords: stars: AGB and post-AGB - stars: carbon - galaxies: dwarf Abstract: Thousands of C stars have been identified in Local Group galaxies using narrow band photometry. To survey C stars at larger distances and alternative to the narrow-band approach is needed. We obtain, from ESO Archive data, NIR magnitudes and colours of previously known C stars in two dwarf irregular Local Group galaxies, namely IC 1613 and NGC 3109. We compare the NIR magnitudes and colours of the C star populations, previously identified from narrow band techniques to estimate the star formation history of their intermediate-age populations. Description: The J and Ks observations of IC 1613 were obtained from the ESO Archive. They consist of NTT data, from La Silla, obtained with the SOFI near infrared camera in September 2004 as part of the Araucaria Cepheid project (Pietrzynski et al., 2006ApJ...642..216P). The NGC 3109 images are also extracted from the ESO Archives. They were obtained with ISAAC at the VLT (Soszynski et al., Cat. J/ApJ/648/375) as part of the Araucaria project. File Summary:
