The joint XMM-Newton and Chandra view of YY Gem
B. Stelzer, V. Burwitz, R. Neuhaeuser +2
We have observed the flare star YY Gem simultaneously with XMM-Newton and Chandra as part of a multi-wavelength campaign aiming at a study of variability related to magnetic activi…
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 Study of the Coronal Plasma in RS CVn binary systems
M. Audard, M. Guedel, A. Sres +5
XMM-Newton has been performing comprehensive studies of X-ray bright RS CVn binaries in its Calibration and Guaranteed Time programs. We present results from ongoing investigations…
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…
