Abstract
A deep near-infrared objective-prism survey for AGB stars in Carina has been carried out. An area of about 20 square degrees centered on l = 290°, b = 0° was covered to I= 13. The identified sample is made of 636 RGB stars of spectral type M5-M9. A sample of AGB stars was also identified, among them 46 N-type carbon stars, and 6 S-type stars. Additionally, 14 red supergiants were also identified. Accurate positions, spectral types and IRAS identifications are given for this sample. The number ratio [C/M5+] in the disc, toward the observed region, was determined giving a value of 0.1-0.2 stars/kpc3, consistent with previous results. A catalog with precise positions, MK spectral types, and infrared I, J, H, and K magnitudes for all the stars in the sample is presented. Cross identifications, where possible, with IRAS and 2MASS catalogs are also given.
