Chandra Observations of Variable Embedded X-ray sources in Orion. Paper I: Resolving Orion Trapezium
N. S. Schulz, C. Canizares, D. Huenemoerder +3
We used the High Energy Transmission Grating Spectrometer (HETGS) onboard the Chandra X-ray Observatory to perform two observations, separated by three weeks, of the Orion Trapeziu…
X-ray Line Emission from the Hot Stellar Wind of theta 1 Ori C
N. S. Schulz, C. R. Canizares, D. Huenemoerder +1
We present a first emission line analysis of a high resolution X-ray spectrum of the stellar wind of theta 1 Ori C obtained with the High Energy Transmission grating Spectrometer o…
High Resolution X-Ray Spectra of Capella: Initial Results from the Chandra High Energy Transmission Grating Spectrometer
C. R. Canizares, D. P. Huenemoerder, D. S. Davis +10
High resolution spectra of the active binary Capella (G8 III + G1 III) covering the energy range 0.4-8.0 keV (1.5-30 Angstroms) show a large number of emission lines, demonstrating…
