HST UV observations of the accretion disk corona X-ray binary X1822-371
Mason, K. O.; Cordova, F. A.; Puchnarewicz, E. M.
The Faint Object Spectrograph on the Hubble Space Telescope has provided the first ultraviolet orbital light curve of the low-mass X-ray binary X1822-371. The shape of the UV light curve changes with wavelength providing the first direct clues to the temperature of the various system components. The data support the idea that the system contains a…
Results from the corrected hubble space telescope
Kinney, A. L.
Findings from the refurbished Hubble Space Telescope are presented, including imaging of asymmetrical circumstellar material around pre-main sequence stars in the Orion Nebula, discovery of a triple ring system in the supernova remnant 1987a, and the measurement of high velocity in the central region of the nucleus of the active galaxy M87 which p…
Ultraviolet eclipse observations of an accretion disk wind
Raymond, J. C.; Mason, K. O.; Cordova, F. A. +3 more
We present eclipse time series of ultraviolet Civ 1549Angstroms and Heii line profiles in the spectrum of the nova-like variable UX UMa, obtained using the Goddard High Resolution Spectrometer (GHRS) on board the Hubble Space Telescope (HST). These data provide important new insights into the origin of these mainly wind-formed lines. Specifically,…
