ADC_Keywords: Clusters, open ; Photometry, infrared ; X-ray sources Keywords: dust, extinction - ISM: individual (Carina Nebula) - open clusters and associations: individual (Trumpler 14 and 16) - stars: early-type - X-rays: stars Abstract: We have carried out near-infrared (NIR) imaging observations of the Carina Nebula for an area of ∼400arcmin^29 including the clusters Trumpler 14 and Trumpler 16, with 10sigma limits of J∼18.5, H∼17.5, and Ks ∼16.5mag. A total of 544 Class II candidates, 11 Class I candidates, and 40 red (H-Ks>2) sources have been found. Description: The NIR imaging observations toward the Carina Nebula were carried out on 2003 April 1, 2, 9, and 10 using the SIRIUS (Simultaneous InfraRed Imager for Unbiased Survey) camera mounted on the IRSF 1.4m telescope in Sutherland, South Africa.
