Scientific paper
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 Nebula" (FGN) from both its optical shape and its lack of detection by the IRAS satellite. We interpret these images in term of a central young bright star of intermediate mass surrounded by a circumstellar disk seen almost perfectly edge-on. We find that the central object is a 4 Msun_ B star and the size and mass of its circumstellar disk are respectively of the order of 1500AU and 0.03Msun_. The Flying Ghost Nebula could be a rare example of an intermediate mass star formed from a flattened structure not yet dissipated.
