Evidence for Accretion in the High-resolution X-ray Spectrum of the T Tauri Star System Hen 3-600
David P. Huenemoerder, Joel H. Kastner, Paola Testa +2
We present high-resolution X-ray spectra of the multiple T Tauri star system Hen 3-600, obtained with the High Energy Transmission Grating Spectrograph on the Chandra X-ray Observa…
On X-ray Optical Depth in the Coronae of Active Stars
Paola Testa, Jeremy J. Drake, Giovanni Peres +1
We have investigated the optical thickness of the coronal plasma through the analysis of high-resolution X-ray spectra of a large sample of active stars observed with the High Ener…
Detailed diagnostics of an X-ray flare in the single giant HR 9024
Paola Testa, Fabio Reale, David Garcia-Alvarez +1
We analyze a 96 ks Chandra/HETGS observation of the single G-type giant HR 9024. The high flux allows us to examine spectral line and continuum diagnostics at high temporal resolut…
