AD Leonis: Flares observed by XMM-Newton and Chandra
E. J. M. van den Besselaar, A. J. J. Raassen, R. Mewe +3
The M-dwarf AD Leonis has been observed with the Reflection Grating Spectrometers and the European Photon Imaging Camera aboard XMM-Newton and also with the Low Energy Transmission…
XMM-Newton Probes the Solar Past: Coronal Abundances of Solar Analogs at Different Ages
M. Guedel, M. Audard, A. Sres +5
We present an X-ray spectral analysis of four solar analogs with different ages and magnetic activity levels. We find largely different coronal compositions. The most active stars…
A Systematic Spectroscopic X-Ray Study of Stellar Coronae with XMM-Newton: Early Results
M. Guedel, M. Audard, K. W. Smith +10
We have been conducting a comprehensive survey of stellar coronae with the XMM-Newton Reflection Grating Spectrometers during the commissioning, calibration, verification, and guar…
A Study of the Coronal Plasma in RS CVn binary systems: HR 1099 and co
M. Audard, M. Guedel, A. Sres +5
XMM-Newton has been performing comprehensive studies of X-ray luminous RS CVn binary systems in its calibration and guaranteed time programs. We present results from ongoing invest…
Helium-like ions as powerful X-ray plasma diagnostics
D. Porquet, R. Mewe, A. J. J Raassen +2
We revisited the calculations of the ratios of the Helium-like ion ``triplet'' (resonance, intercombination, and forbidden lines) for Z=6 to 14 (C V, N VI, O VII, Ne IX, Mg XI, Si…
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…
