dc.description.abstract	Optical candidates of 17 unidentified IRAS sources with far-infrared colors similar to planetary nebulae have been detected on sky survey plates. Low resolution CCD spectra of seven optical candidates suggests that they are post asymptotic giant branch (AGB) A-F-G supergiants. Their location in the Hertzsprung-Russell (HR) diagram and the presence of detached cold dust shells with far-infrared colors similar to planetary nebulae suggests that they are low mass stars and have been experienced severe mass loss in the recent past during their AGB stage of evolution.	en
