Chandra Observations of WZ Sge in Superoutburst
Peter J. Wheatley, Christopher W. Mauche
We present seven separate Chandra observations of the 2001 superoutburst of WZ Sge. The high-energy outburst was dominated by intense EUV emission lines, which we interpret as boun…
Chandra HETG Spectra of SS Cyg and U Gem in Quiescence and Outburst
Christopher W. Mauche, Peter J. Wheatley, Knox S. Long +2
Chandra HETG spectra of the prototypical dwarf novae SS Cyg and U Gem in quiescence and outburst are presented and discussed. When SS Cyg goes into outburst, it becomes dimmer in h…
The Fe XXII I(11.92 A)/I(11.77 A) Density Diagnostic
Christopher W. Mauche, Duane A. Liedahl, Kevin B. Fournier
Using the Livermore X-ray Spectral Synthesizer, which calculates spectral models of highly charged ions based on HULLAC atomic data, we investigate the temperature, density, and ph…
The Spin-Up Rate of the White Dwarf of GK Per
Christopher W. Mauche
We use hard X-ray light curves measured by the Chandra HETG and RXTE PCA during the late rise and plateau phases of the 2002 March-April outburst of the intermediate polar GK Per t…
EUVE Phase-Resolved Spectroscopy of V834 Centauri
Christopher W. Mauche
(abridged) The Extreme Ultraviolet Explorer (EUVE) satellite was employed in 1999 February to acquire phase-resolved EUV photometric and spectroscopic observations of the AM Her-ty…
Plasma Diagnostics in High-Resolution X-ray Spectra of Magnetic Cataclysmic Variables
Christopher W. Mauche
Using the Chandra HETG spectrum of EX Hya as an example, we discuss some of the plasma diagnostics available in high-resolution X-ray spectra of magnetic cataclysmic variables. Spe…
