Helium-like triplet density diagnostics: Applications to CHANDRA--LETGS X-ray observations of Capella and Procyon
J. U. Ness, R. Mewe, J. H. M. M. Schmitt +6
Electron density diagnostics based on the triplets of Helium-like CV, NVI, and OVII are applied to the X-ray spectra of Capella and Procyon measured with the Low Energy Transmissio…
An optical and X-ray study of the peculiar narrow-line quasar QSO 0117-2837
Stefanie Komossa, D. Grupe, V. Burwitz +1
We present an optical and X-ray study of the quasar QSO 0117-2837. It exhibits an interesting combination of optical and X-ray properties: Despite its extremely steep observed X-ra…
First Light Measurements of Capella with the Low Energy Transmission Grating Spectrometer aboard the Chandra X-ray Observatory
A. C. Brinkman, C. J. T. Gunsing, J. S. Kaastra +20
We present the first X-ray spectrum obtained by the Low Energy Transmission Grating Spectrometer (LETGS) aboard the Chandra X-ray Observatory. The spectrum is of Capella and covers…
