On the infrared emission of the exciting star of the Herbig-Haro objects 1 and 2.
Abstract
Further evidence is presented indicating that the infrared emission at λ > 3 μm, spatially coincident with the VLA source located midway between the Herbig-Haro objects 1 and 2, comes from warm circumstellar dust around the star most probably responsible for the excitation of these Herbig-Haro objects. The nearby extended emission dominating at shorter wavelengths comes from scattered stellar light, the shocked ionized nebulosity, or both. The visual extinction in the direction of the central star is 23 ⪉ AV ⪉ 63.
