Abstract: (4411 Views)
In this paper, we analyze, near infra red images of the central region of the local group galaxy M33. These images were obtained in K band with the UFTI instrument, installed on the UKIRT telescope. This is a part of a bigger project started in 2003 with an aim to investigate RGB and AGB stars in M33. K band magnitude was obtained for 18509 stars by fitting appropriate PSF models to stellar profiles in the images. The final catalogue was obtained by calibrating instrumental magnitude to standard system. Cross correlation methods was manipulated to assign J-K color index to each star. A color magnitude diagram was plotted which represents population of RGB, AGB and Carbon stars in the core of M33 galaxy
