The all-sky survey conducted by
the InfraRed Astronomical Satellite (IRAS) in the
1980’s discovered many objects with infrared excesses
whose nature has not been explored until recently.
IRAS07080+0605 is one of those identified in the
visual spectral range with an early-type star, which
shows the B[e] phenomenon. The object is puzzling,
because it exhibits one of the strongest infrared
excesses associated with a star of one of the lowest
surface temperatures (∼8500 K) among objects with
the B[e] phenomenon, an apparent combination of
spectral features of dwarfs and supergiants, and
the absence of a surrounding optical nebula. Our
photometric and spectroscopic study shows that the
object’s properties are similar to those of the famous
Red Rectangle proto-planetary nebula. In this paper
we describe our findings and hypotheses about the
nature and evolutionary status of IRAS07080+0605
