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.
