Fe K alpha and hydrodynamic loop model diagnostics for a large flare on II Peg
Barbara Ercolano, Jeremy J. Drake, Fabio Reale +2
The observation by the Swift X-ray Telescope of the Fe K alpha_1, alpha_2 doublet during a large flare on the RS CVn binary system II Peg represents one of only two firm detections…
X-ray irradiated protoplanetary disk atmospheres I: Predicted emission line spectrum and photoevaporation
Barbara Ercolano, Jeremy J. Drake, John C. Raymond +1
We present MOCASSIN 2D photoionisation and dust radiative transfer models of a prototypical T Tauri disk irradiated by X-rays from the young pre-main sequence star. The calculation…
On the Detectability of Oxygen X-ray Fluorescence and its Use as a Solar Photospheric Abundance Diagnostic
Jeremy J. Drake, Barbara Ercolano
Monte Carlo calculations of the O Kalpha line fluoresced by coronal X-rays and emitted just above the temperature minimum region of the solar atmosphere have been employed to inves…
Geometry Diagnostics of a Stellar Flare from Fluorescent X-rays
P. Testa, J. J. Drake, B. Ercolano +5
We present evidence of Fe fluorescent emission in the Chandra HETGS spectrum of the single G-type giant HR 9024 during a large flare. In analogy to solar X-ray observations, we int…
