Temperature distribution of a non-flaring active region from simultaneous Hinode XRT and EIS observations
Paola Testa, Fabio Reale, Enrico Landi +2
We analyze coordinated Hinode XRT and EIS observations of a non-flaring active region to investigate the thermal properties of coronal plasma taking advantage of the complementary…
Element abundances in X-ray emitting plasmas in stars
Paola Testa
Studies of element abundances in stars are of fundamental interest for their impact in a wide astrophysical context, from our understanding of galactic chemistry and its evolution,…
Detailed X-Ray Line Properties of Theta2 Ori A in Quiescence
Arik W. Mitschang, Norbert S. Schulz, David P. Huenemoerder +2
We investigate X-ray emission properties of the peculiar X-ray source Theta2 Ori A in the Orion trapezium region using more than 500 ksec of HETGS spectral data in the quiescent st…
X-ray emission processes in stars
Paola Testa
A decade of X-ray stellar observations with Chandra and XMM-Newton has led to significant advances in our understanding of the physical processes at work in hot (magnetized) plasma…
X-ray Flares of EV Lac: Statistics, Spectra, Diagnostics
David P. Huenemoerder, Norbert S. Schulz, Paola Testa +3
We study the spectral and temporal behavior of X-ray flares from the active M-dwarf EV Lac in 200 ks of exposure with the Chandra/HETGS. We derive flare parameters by fitting an em…
