Multiwavelength studies of the gas and dust disc of IRAS 04158+2805
A. M. Glauser, F. Ménard, C. Pinte +4
We present a study of the circumstellar environment of IRAS 04158+2805 based on multi-wavelength observations and models. Images in the optical and near-infrared, a polarisation ma…
The X-ray soft excess in classical T Tauri stars
M. Guedel, A. Telleschi
We study an anomaly in the X-ray flux (or luminosity) ratio between the OVII 21.6-22.1A triplet and the OVIII Lya line seen in classical T Tauri stars (CTTS). This ratio is unusual…
XMM-Newton X-ray Observations of the Wolf-Rayet Binary System WR 147
S. L. Skinner, S. A. Zhekov, M. Guedel +1
We present results of a 20 ksec X-ray observation of the Wolf-Rayet (WR) binary system WR 147 obtained with XMM-Newton. Previous studies have shown that this system consists of a n…
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-…
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-ray emission from the young brown dwarfs of the Taurus Molecular Cloud
N. Grosso, K. R. Briggs, M. Guedel +9
The XMM-Newton Extended Survey of the TMC (XEST) is a large program designed to systematically investigate the X-ray properties of young stellar/substellar objects in the TMC. In p…
