X-ray/UV campaign on the Mrk 279 outflow: density diagnostics in Active Galactic Nuclei using O V K-shell absorption lines
J. S. Kaastra, A. J. J. Raassen, R. Mewe +6
One of the main problems in modeling the ionised outflows in Active Galactic Nuclei is the unknown distance of the outflowing wind to the central source. Only if the density is kno…
The X-ray spectra of the flaring and quiescent states of AT Microscopii observed by XMM-Newton
A. J. J. Raassen, R. Mewe, M. Audard +1
The X-ray spectrum of the late-type M-dwarf binary AT Mic (dM4.5e+dM4.5e) is observed in the wavelength range 1 - 40 Angstrom by means of rgs and epic-mos on board XMM-Newton. Duri…
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…
Stellar Coronae with \textit{XMM-Newton} RGS. I. Coronal Structure
M. Guedel, M. Audard, A. J. den Boggende +16
First results from high-resolution coronal spectroscopy with the {\it XMM-Newton} Reflection Grating Spectrometers (RGS) are reviewed. Five stellar systems (HR 1099, Capella, Procy…
