The Extreme Ultraviolet Imager Investigation for the IMAGE Mission
The Extreme Ultraviolet Imager (EUV) of the IMAGE Mission will study the distribution of He in Earth’s plasmasphere by detecting its resonantly-scattered emission at 30.4 nm. It will record the structure and dynamics of the cold plasma in Earth’s plasmasphere on a global scale. The 30.4-nm feature is relatively easy to measure because it is the brightest ion emission from the plasmasphere, it i...
متن کاملThe Extreme Physics Explorer
Some tests of fundamental physics the equation of state at supra-nuclear densities, the metric in strong gravity, the effect of magnetic fields above the quantum critical value can only be measured using compact astrophysical objects: neutron stars and black holes. The Extreme Physics Explorer is a modest sized (∼500 kg) mission that would carry a high resolution (R ∼300) X-ray spectrometer and...
متن کاملDeuterium toward the White Dwarf Wd0621−376: Results from the Far Ultraviolet Spectroscopic Explorer (fuse) Mission
Far Ultraviolet Spectroscopic Explorer observations are presented for WD0621−376, a DA white dwarf star in the local interstellar medium (LISM) at a distance of about 78 pc. The data have a signal-tonoise ratio of ∼20–40 per 20 km s resolution element and cover the wavelength range 905–1187 Å. LISM absorption is detected in the lines of D I, C II, C II*, C III, N I, N II, N III, O I, Ar I, and ...
متن کاملDeuterium Abundance toward Wd2211−495 : Results from the Far Ultraviolet Spectroscopic Explorer (fuse) Mission
We present a deuterium abundance analysis of the line of sight toward the white dwarf WD2211−495 observed with the Far Ultraviolet Spectroscopic Explorer (FUSE). Numerous interstellar lines are detected on the continuum of the stellar spectrum. A thorough analysis was performed through the simultaneous fit of interstellar absorption lines detected in the four FUSE channels of multiple observati...
متن کاملDeuterium toward Wd 1634-573: Results from the Far Ultraviolet Spectroscopic Explorer (fuse) Mission
We use Far Ultraviolet Spectrocopic Explorer (FUSE) observations to study interstel-lar absorption along the line of sight to the white dwarf WD 1634-573 (d = 37.1±2.6 pc).
