He2-36 - A planetary nebula with a high velocity jet?
Abstract
The ultraviolet spectrum of the planetary nebula He2-36 was observed in the low-dispersion mode of the IUE. Strong emission lines of semiforbidden C III, He II, and C IV are observed, as well as some weak line and a moderately strong stellar continuum, suggesting a hot companion to the visual A2 III central star. The extinction to He2-36 was determined from the He II I (1640)/I (4686) ratio. The C IV line has an unusual split structure. If the 1545 component is due to a blueshifted component from the 'jet' emanating from the nebula, its velocity would be -600 km/s, which is unique for a planetary nebula.
