THE FLYING-GHOST-NEBULA - A REMARKABLE CIRCUMSTELLAR DISK

We present high resolution images in the photometric bands V, R, I, J, H and K of a remarkable bipolar nebula we named the ''Flying Ghost Ne bula'' (FGN) from both its optical shape and its lack of detection by the IRAS satellite. We interpret these images in term of a central you ng bright star of intermediate mass surrounded by a circumstellar disk seen almost perfectly edge-on. We find that the central object is a 4 M. B star and the size and mass of its circumstellar disk are respect ively of the order of 1500 AU and 0.03 M. The Flying Ghost Nebula coul d be a rare example of an intermediate mass star formed from a flatten ed structure not yet dissipated.
