Abstract
We present infrared J, H and H observations of 69 local galactic halo stars. We produce the two colour (JHK) and the colour magnitude (K ver sus (J - K)) diagrams for this stellar sample and compare them with th e same diagrams for the stellar populations in the globular clusters M 3, M13, M92 and 47 Tucanae and in the old open cluster M67; we also co mpare these diagrams with those for the stellar population in the gala ctic bulge.
