On the nature of AFGL 2477.

Abstract (from CDS):
Because of its bimodal spectral energy distribution and featureless LRS spectrum, AFGL 2477 has been suggested to be a carbon-rich post-AGB star. In this paper we argue against this hypothesis (based on our finding that the alleged optical counterpart is oxygen-rich) and propose that there are two stars close together on the sky (within 5" of each other) which probably are not physically related. A more exotic scenario is also discussed.
