We present JHK observations of Leo I and Leo II dwarf spheroidal galaxies obtained with the WFCAM@UKIRT. The wide field of view and the good photometric quality of the camera led to the first high-precision NIR photometric catalogue obtained so far for these two galaxies. With high-precision photometry we could isolate the foreground Galactic population and disentangle oxygen- and carbon-rich AGB stars. Our data are compared with predictions of the most recent theoretical AGB models.

Abstract
We present JHK observations of Leo I and Leo II dwarf spheroidal galaxies obtained with the WFCAM@UKIRT. The wide field of view and the good photometric quality of the camera led to the first high-precision NIR photometric catalogue obtained so far for these two galaxies. With high-precision photometry we could isolate the foreground Galactic population and disentangle oxygen- and carbon-rich AGB stars. Our data are compared with predictions of the most recent theoretical AGB models.File in questo prodotto:
