“…The relevant parameters are: the total luminosity (obtained from integration of the SED, but dependent on the anisotropy of the dust-processed radiation, see below), the central mass (from the nebula rotation), and the stellar surface temperature (see discussion on the stellar type accuracy by Berné et al 2009). If the stellar type is slightly less early than proposed by Ruiz et al (1987), a distance of about 300 pc is consistent with all existing data. These smaller values of distance yield a slightly smaller linear radius for the disk, in closer agreement with results found for similar objects.…”

“…GoHam was originally proposed to be a post-AGB nebula (Ruiz et al 1987). However, high-resolution CO maps (Bujarrabal et al 2008, hereafter, Paper I) were used to demonstrate that the nebula is almost exactly in Keplerian rotation, around the symmetry axis clearly identifiable in its image.…”

“…When first studied by Ruiz et al (1987), it was classified as an evolved object (post-AGB star) on the basis of its spectral type and the presence of dust. However, all recent studies (Bujarrabal et al 2008(Bujarrabal et al , 2009Wood et al 2008;De Beck et al 2010) clearly indicate that it is a young A star surrounded by a protoplanetary disk.…”

“…Gomez's Hamburger (IRAS 18059-3211; hereafter GoHam) is a southern nebula with a very spectacular appearance in the optical (see Ruiz et al 1987, and HST images in press release number 2002/19): an obscuring lane separates two flat, bright regions, presumably illuminated by a central star that remains hidden by the equatorial disk. The nebula was originally identified on a plate by A. Gómez, in 1985.…”
