Planetary Nebulae: Individual: K3-82 (Png093.3-00.9)

Scientific paper

In this paper we present Fabry-P{e}rot high resolution spectroscopy in Hα , Hβ , [O\ion{iii}], and [N\ion{ii}], optical low resolution spectroscopy spanning the usable range 4700-6800{ Angstroms}, along with a broad band direct image in Gunn-red for the planetary nebula (PN) K3-82. K3-82 turned out to be highly symmetrical, seen most probably edge-on. Two point-symmetrical knots appear in the light of Gunn-red. These knots either represent concentrated emission regions or are part of an incomplete equatorial waist of K3-82. Our results for the systemic velocity is -62.4+/-5km/s and for the average expansion velocity 30+/-5km/s. For the distance we determined a minimum value of 2.5kpc. The [S\ion{ii}] ion indicates a very low density within the knots of K3-82.
