Redshifted emission lines and radiative recombination continuum from the Wolf-Rayet binary theta Muscae: evidence for a triplet system?
Yasuharu Sugawara, Yohko Tsuboi, Yoshitomo Maeda
We present XMM-Newton observations of the WC binary Theta Muscae (WR 48), the second brightest Wolf-Rayet binary in optical wavelengths. The system consists of a short-period (19.1…
The young stellar population in M17 revealed by Chandra
Patrick S. Broos, Eric D. Feigelson, Leisa K. Townsley +5
We report here results from a Chandra ACIS observation of the stellar populations in and around the Messier 17 H II region. The field reveals 886 sources, 771 of which have stellar…
X-ray and Near-infrared Studies of a Star-forming Cloud; L1448
M. Tsujimoto, N. Kobayashi, Y. Tsuboi
We present the results of X-ray and near-infrared (NIR) observations of L1448, a star-forming region in the Perseus cloud complex using the Chandra X-ray Observatory and the 4 m te…
X-rays from Cepheus A East and West
Steven H. Pravdo, Yohko Tsuboi
We report the discovery of X-rays from both components of Cepheus A, East and West, with the XMM-Newton Observatory. HH 168 joins the ranks of other energetic Herbig Haro objects t…
Iron Fluorescent Line Emission from Young Stellar Objects in the Orion Nebula
M. Tsujimoto, E. D. Feigelson, N. Grosso +5
We present the result of a systematic search for the iron Kalpha fluorescent line at 6.4 keV among 1616 X-ray sources detected by ultra-deep Chandra observations of the Orion Nebul…
X-rays from HH 80, HH 81, and the Central Region
Steven H. Pravdo, Yohko Tsuboi, Yoshitomo Maeda
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 HH sources in the optical and they…
