X-rays from T Tau: A test case for accreting T Tauri stars
M. Guedel, S. L. Skinner, S. Yu. Mel'nikov +3
We test models for the generation of X-rays in accreting T Tauri stars (TTS), using X-ray data from the classical TTS T Tau. High-resolution spectroscopy from the Reflection Gratin…
Hard X-rays and Fluorescent Iron Emission from the Embedded Infrared Cluster in NGC 2071
Stephen L. Skinner, Audrey E. Simmons, Marc Audard +1
We present first results of XMM-Newton X-ray observations of the infrared cluster lying near the NGC 2071 reflection nebula in the Orion B region. This cluster is of interest becau…
The first high-resolution X-ray spectrum of a Herbig Star: The case of AB Aurigae
A. Telleschi, M. Guedel, K. R. Briggs +3
We present the first high-resolution X-ray spectrum of a prototypical Herbig star (AB Aurigae), measure and interpret various spectral features, and compare our results with model…
X-rays from jet-driving protostars and T Tauri stars
M. Guedel, A. Telleschi, M. Audard +4
(abridged:) We study X-rays from jet-driving protostars and T Tau stars. We seek soft spectral components that may be due to shock emission, and shock-induced emission displaced fr…
The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST)
M. Guedel, K. R. Briggs, K. Arzner +18
(abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newt…
The Chandra X-ray Spectrum of the 10.6 s Pulsar in Westerlund 1: Testing the Magnetar Hypothesis
S. L. Skinner, R. Perna, S. A. Zhekov
Two sensitive Chandra X-ray observations of the heavily-reddened galactic starburst cluster Westerlund 1 in May and June 2005 detected a previously unknown X-ray pulsar (CXO J16471…
The Unusual X-ray Spectrum of FU Orionis
S. L. Skinner, K. R. Briggs, M. Guedel
FU Orionis stars (FUors) are young low-mass eruptive stars that are thought to be accreting at high rates. They could give rise to soft X-ray emission from accretion shocks, but th…
A Rich Population of X-ray Emitting Wolf-Rayet Stars in the Galactic Starburst Cluster Westerlund 1
S. L. Skinner, A. E. Simmons, S. A. Zhekov +3
Recent optical and IR studies have revealed that the heavily-reddened starburst cluster Westerlund 1 (Wd 1) contains at least 22 Wolf-Rayet (WR) stars, comprising the richest WR po…
