J/ApJ/605/259       X-rays from HH 80/81 complex             (Pravdo+, 2004)

X-rays from HH 80, HH 81, and the central region. Pravdo S.H., Tsuboi Y., Maeda Y. <Astrophys. J., 605, 259-271 (2004)> =2004ApJ...605..259P
ADC_Keywords: X-ray sources ; Stars, pre-main sequence ; Photometry Keywords: ISM: Herbig-Haro objects - ISM: individual (HH 80, HH 81) - X-rays: ISM Abstract: We report detections of X-rays from HH 80 and HH 81 with the ACIS instrument on the Chandra X-Ray Observatory. These are among the most luminous Herbig-Haro (HH) sources in the optical, and they are now the most luminous known in X-rays. These X-rays arise from the strong shocks that occur when the southern extension of this bipolar outflow slams into the ambient material. We imaged the central region of the bipolar flow revealing a complex of X-ray sources, including one near but not coincident with the putative power source in the radio and infrared. Description: We searched for X-ray emission from the HH 80/81 complex in a 37.3ks Chandra X-Ray Observatory (Weisskopf et al., 2002PASP..114....1W) observation on 2002 November 4.
