Abstract
This paper presents the J, H, K, L, M photometry of 516 sources pertaining to a sample of 787 sources which has been extracted from the IRAS Point Source Catalogue in order to study the late stages of stellar evolution and the concomitant phenomena of mass loss. Three different classifications of these sources based on broadband photometry and IRAS low resolution spectra are given, and the distributions of the sources in terms of these classifications are presented. A sub-sample of peculiar sources, believed to have recently undergone a helium flash, has been isolated using the K - L, [12-mu-m] - [25-mu-m] colour diagram. Some objects worth further studies are also mentioned.
