Abstract:   (4313 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
