Spectrophotometric and model-atmosphere analyses of the hot DO and DAO white dwarfs from the Palomar-Green survey.
Wesemael, F.; Green, R. F.; Liebert, J.
Recent optical and spectrophotometric observations of all currently known DAO and DO hot white dwarf candidates from the Palomar-Green Survey are presented. The optical observations were carried out using the Kitt Peak National Observatory Intensified Image Dissector Scanner (IIDS) system, the Multiple Mirror Telescope (MMT), and two photon-counti…
Ultraviolet interstellar absorption toward stars in the Small Magellanic Cloud. III. The structure and kinematics of the Small Magellanic Cloud.
Fitzpatrick, E. L.
The structural and kinematic properties of the Small Magellanic Cloud (SMC) were studied by combining IUE satellite observations of individual bright stars (Sk 159 and HD 5980) with existing optical and radio data. It is shown that the SMC has a complex structure due to gravitational interaction with the Milky Way and the Large Magellanic Cloud (L…
An ultraviolet line list for O star spectra.
Bruhweiler, F. C.; Dean, C. A.
Archival high dispersion UV spectra obtained by the IUE satellite, together with laboratory data for the Fe peak ions, reveal more than 550 identifiable spectral features in the far-UV region in the cases of the O subdwarfs BD +75 deg 325 and BD +28 deg 4211, as well as the sharp lined main sequence star HD 46202. The wide range of effective tempe…
Line identifications, line strengths and continuum flux measurements in the ultraviolet spectrum of Arcturus.
Carpenter, K. G.; Stencel, R. E.; Wing, R. F.
The ultraviolet spectrum of Arcturus has been observed at high resolution with the IUE satellite. Line identifications, mean absolute 'continuum' flux measurements, integrated absolute emission-line fluxes, and measurements of selected absorption line strengths are presented for the 2250-2930 A region. In the 1150-2000 A region, identifications ar…
IUE spectra of GO V-G5 V solar-type stars.
Basri, G.; Haisch, B. M.
An atlas of IUE short-wavelength spectra for a set of 14 bright G0 V-G5 V stars are presented, and it is shown that these manifest a range of qualitatively different chromospheric and transition region spectra and significant differences in radiative flux originating at the temperature minimum level. A comprehensive survey of observational data an…
High-dispersion ultraviolet spectra of the peculiar star RX Puppis.
Kafatos, M.; Michalitsianos, A. G.; Fahey, R. P.
High spectral resolution observations of the peculiar star RX Puppis obtained with the International Ultraviolet Explorer suggest the presence of a complex gaseous ring system which surrounds an accreting hot secondary. The anomalous line intensity ratio of the C IV 1548, 1550 A doublet during the observations exceeded the optically thick limit, i…
