ORFEUS II and IUE Spectroscopy of EX Hydrae
Using five high-resolution (λ/∆λ ≈ 3000) FUV (λλ = 910–1210 Å) spectra acquired in 1996 December during the flight of the ORFEUS-SPAS II mission, 47 archival IUE short-wavelength UV (λλ = 1150–1950 Å) spectra, and archival EUVE deep survey photometry (λλ ≈ 70–200 Å), we present a detailed picture of the behavior of the magnetic cataclysmic variable EX Hydrae in the vacuum ultraviolet. Like HUT ...
متن کاملIUE Observations of Faint Comets
Ultraviolet spectra of seven comets taken with the same instrument are presented. Comets P/Encke (1980), P/Tuttle (1980 h), P/Stephan-Oterma (1980 g), and Meier (1980 q) were observed during November-December 1980 with the International Ultraviolet Explorer (IUE) satellite observatory, while comets P/Borrelly (1980 i) and Panther (1980 u) were observed with IUE on 6 March 1981. The spectra of t...
متن کاملIue Observations of Luminous Blue Star Associations in Irregular Galaxies
Ir'reguJar galaxies offer a special opportunity for the study of massive star formation. They are the bluest of galaxies, as a class, and this, together with the optical emission line spectra observed for some, indicates that massive stars are currently being formed. We are particularly interested in exploring the high mass end of the initial mass function (IMF) and the spatial patterns of star...
متن کاملSome Properties of rw-Sets and rw-Continuous Functions
In 1937, Stone [6] introduced and investigated the regular open sets. These sets are contained in the family of open sets since a set is regular open if it is equal to the interior of its closure. In 1978, Cameron [2] also introduced and investigated the concept of a regular semiopen set. A set A is regular semiopen if there is a regular open set U such that U ⊆ A ⊆ U . In 2007, a new class of ...
متن کاملThe Far-ultraviolet Spectrum of Tw Hydrae. I. Observations of H2 Fluorescence
We observed the classical T Tauri star TW Hya with the Space Telescope Imaging Spectrograph on board theHubble Space Telescope (HST) using the E140M grating, from 1150 to 1700 Å, with the E230M grating, from 2200 to 2900 Å, and with the Far Ultraviolet Spectroscopic Explorer from 900 to 1180 Å. Emission in 146 Lyman-band H2 lines, representing 19 progressions, dominates the spectral region from...
