X-Ray Spectral Variability During an Outburst in V1118 Ori
M. Audard, M. Guedel, S. L. Skinner +5
We present results from a multi-wavelength campaign to monitor the 2005 outburst of the low-mass young star V1118 Ori. Although our campaign covers the X-ray, optical, infrared, an…
An XMM-Newton Study of the Coronae of Coronae Borealis
J. A. Suh, M. Audard, M. Guedel +1
(Abridged) We present results of XMM-Newton observations of the RS CVn binary Coronae Borealis. The RGS and EPIC MOS2 spectra were simultaneously fitted with collisional ioni…
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…
Flares observed with XMM-Newton and the VLA
K. W. Smith, M. Guedel, M. Audard
We present lightcurves obtained in X-ray by the XMM-Newton EPIC cameras and simultaneous radio lightcurves obtained with the VLA for five active M-type flare stars. A number of fla…
