Discovery of an Optical Jet in the Rosette Nebula: Rosette HH2
Abstract
We report on the discovery of an optical jet -- Rosette HH2 -- in the Rosette Nebula. The jet system bears unique features for residing at the center of a giant HII region, and its energy source is visible with apparently very low extinction along the line of sight. Unlike most other Herbig-Haro jets, this jet indicates a high-excitation origin, and its extended portion shows a seemingly intact structure, instead of normally a shocked working surface, which is attributed to photoablation.
