dc.description.abstractThe FIR IRAS flux distributions and color of 12 peculiar emission-line objects (HD 51585, Hen 401, Hen 591, Hen 1013, He 2-138, M 2-9, HD 326971, Hen 1357, Hen 1428, Tc 1, Hen 1475, and M 1-26) are found to be similar to that observed in young compact planetary nebulae. From the FIR fluxes the temperatures, luminosities, and masses of the dust envelopes are estimated. The results suggest that these 12 peculiar emission line stars suffered extensive mass loss in the past on their AGB stage of evolution. These objects appear to be evolving toward the early stages of planetary nebulae and may be described as transition objects or possible protoplanetary nebulae.en
