Descripción
We have discovered an object in the field of the Galactic open cluster
[1]36 which exhibits a nebulous tail-like structure and a high velocity
outflow. We first observed the jet morphology in optical images taken at
the Michigan-Dartmouth-MIT (MDM) Observatory at Kitt Peak. This source,
located at 05h36min05.9s, 34deg06'12.1" (J2000), is found to be
coincident with IRAS 05327+3404. CO(1-0) observations (Wouterloot &
Brand 1989) showed this object to be a strong emission-line source. We
performed CO(2-1) observations at the James-Clerk-Maxwell Telescope at
Mauna Kea which suggest that the outflow is bipolar in nature. Optical
spectroscopy obtained at the La Palma Isaac-Newton 2.5m Telescope shows
strong emission lines, reminiscent of Herbig-Haro emission and
confirming the outflow. The object is probably not associated with
[1]36, and may be a far-flung member of the nearby region of star
formation, S235. The optical spectra are quite unusual. We conclude that
the spectra represent two views of the same jet structure from different
viewing angles, one the result of a reflection off the nebulous tail.
The IRAS fluxes, optical morphology, and aspects of the optical spectra
are similar to the FU Orionis system L1551 IRS5, and may indicate that
this object is also an FU Orionis star.
