Young stellar objects from soft to hard X-rays
M. Guedel
Magnetically active stars are the sites of efficient particle acceleration and plasma heating, processes that have been studied in detail in the solar corona. Investigation of such…
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…
