Hubble Space Telescope imaging of IRAS 17441-2411: a case study of a bipolar nebula with a circumstellar disk.

Abstract (from CDS):

The bipolar proto-planetary nebula IRAS 17441-2411 (the ``Silkworm Nebula'') was observed with the Hubble Space Telescope. By fitting the observed spectral energy distribution and the V-band image by a two-dimensional radiation transfer model, we derive the properties of the circumstellar wind and a proposed circumstellar ``disk.'' We suggest that bipolar structures are probably more common than actually observed, because objects with similar intrinsic structures may simply appear stellar because of their orientation in the sky.
