Evidence for an X-Ray Jet in DG Tau A?
M. Guedel, S. L. Skinner, K. R. Briggs +3
We present evidence for an X-ray jet in the T Tau star DG Tau A based on Chandra ACIS data. DG Tau A, a jet-driving classical T Tau star with a flat infrared spectrum, reveals an u…
Spot the differences: The X-ray spectrum of SU Aur compared to TW Hya
K. Smith, M. Audard, M. Guedel +2
We present high-resolution Chandra HETGS X-ray spectra of the classical T Tauri star SU Aur. The quiescent X-ray emission is dominated by a 20-40 MK plasma, which contrasts strongl…
A Deep Look at the T-Type Brown Dwarf Binary Indi Bab with Chandra and ATCA
M. Audard, A. Brown, K. R. Briggs +3
We present deep observations of the nearby T-type brown dwarf binary Indi Bab in radio with the Australia Telescope Compact Array and in X-rays with the Chandra X-ray Observato…
Stellar Coronae with \textit{XMM-Newton} RGS. II. X-ray Variability
M. Audard, M. Guedel, A. J. den Boggende +16
First results from high-resolution coronal spectroscopy of flares with the Reflection Grating Spectrometers on board the \textit{XMM-Newton} satellite are reviewed. Rotational modu…
