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…
X-ray Emission from T Tauri Stars and the Role of Accretion: Inferences from the XMM-Newton Extended Survey of the Taurus Molecular Cloud
A. Telleschi, M. Guedel, K. R. Briggs +2
T Tau stars display different X-ray properties depending on whether they are accreting (classical T Tau stars; CTTS) or not (weak-line T Tau stars; WTTS). We use data from the XMM-…
Spectral properties of X-ray bright variable sources in the Taurus Molecular Cloud
E. Franciosini, I. Pillitteri, B. Stelzer +7
We analyze 19 bright variable X-ray sources detected in the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), in order to characterize the variations with time of th…
The XMM-Newton Optical Monitor Survey of the Taurus Molecular Cloud
Marc Audard, Kevin Briggs, Nicolas Grosso +4
The Optical Monitor (OM) on-board XMM-Newton obtained optical/ultraviolet data for the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), simultaneously with the X-ra…
High Resolution X-ray Spectroscopy of T Tauri Stars in the Taurus-Auriga Complex
A. Telleschi, M. Guedel, K. R. Briggs +2
Differences have been reported between the X-ray emission of accreting and non-accreting stars. Some observations have suggested that accretion shocks could be responsible for part…
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…
A U-band survey of brown dwarfs in the Taurus Molecular Cloud with the XMM-Newton Optical/UV Monitor
Nicolas Grosso, Marc Audard, Jérôme Bouvier +4
We aim to characterize the U-band variability of young brown dwarfs in the Taurus Molecular Cloud and discuss its origin. We used the XMM-Newton Extended Survey of the Taurus Molec…
A statistical analysis of X-ray variability in pre-main sequence objects of the Taurus Molecular Cloud
B. Stelzer, E. Flaccomio, K. Briggs +5
This work is part of a systematic X-ray survey of the Taurus star forming complex with XMM-Newton. We study the time series of all X-ray sources associated with Taurus members, to…
