Herbig-Haro objects 1 and 2 : another infrared candidate for their energy source.
Abstract
A possible source for the excitation energy of Herbig-Haro objects 1 and 2 has been detected at wavelengths of 1 - 4 μm. Its position coincides with a recent detection of a 6-cm radio continuum source and the centre of an NH3 torus orientated perpendicularly to the line joining H-H 1 and 2. Its infrared (1 - 200 μm) luminosity is approximately 10 L_sun;, consistent with a reddened (AV ≅ 12) T Tauri-type star. From upper limits in visual and near-infrared plates and from infrared photometry, a reddening law which resembles that of the Orion Belt and Sword regions has been calculated.
