Evidence for sulphur implantation in Europa's UV absorption band
Matson, D. L.; Nelson, R. M.; Lane, A. L.
The International Ultraviolet Explorer (IUE) spacecraft has obtained observations of the galilean satellites over the past 2 years which fortuitously span the periods of the Voyager encounters with the jovian system. Our IUE observing programme is designed to determine the UV spectral characteristics of the galilean satellites as a function of orb…
The nearby interstellar medium
Frisch, P. C.
The high dispersion spectrometer on board the International Ultraviolet Explorer (IUE) satellite was used to observe interstellar absorption lines in Rasalhague (α Oph). This star is located 18 pc from the Sun in the direction of the North Polar Spur, a prominent radio continuum feature in the Ophiuchus region of the sky. The satellite results, co…
H2 emission in the EUV spectrum of T Tauri and Burnham's nebula
Jordan, C.; Wilson, R.; Brown, A. +2 more
Emission in the Lyman bands of H2 has been detected in an extreme ultraviolet (EUV) spectrum of T Tauri and its adjacent nebula, obtained with the international UV explorer (IUE) satellite. We report here that the emission is in a progression which can be excited through fluorescence with the red wing of the H Lyα line, as found also in…
IUE detection of bursts of H LYα emission from Saturn
Moos, H. W.; Atreya, S. K.; Clarke, J. T. +1 more
An extended source of H Lyα emission (1,216 Å) from the vicinity of Saturn has been detected previously by a rocket-borne spectrometer1, the OAO-Copernicus satellite2, and the Pioneer 11 spacecraft3. During the rocket experiment, in which Saturn was observed on 15 March 1975, 700 R+/-50% of Lyα emission was detecte…
Galactic γ and radio synchrotron radiation
Osborne, J. L.; Phillipps, S.; Haslam, C. G. T. +2 more
The galactic γ-radiation and radio synchrotron radiation contains information on the distribution of cosmic-ray particles, magnetic field and gas throughout the Galaxy. We report here a new all-sky survey of 408-MHz radio continuum which has been used to compare the distributions of radio and γ-ray emission, with the former convolved to the respon…
UV observations of X-ray sources 2A 0311-227 and 2A 0526-328.
Coe, M. J.; Wickramasinghe, D. T.
IUE satellite observations of the X-ray sources 2A0311-227 and 2A0526-328, which are suspected to be AM Her-type dwarf novae, are reported. Spectra were obtained by the long-wavelength (1900-3200 A) and short-wavelength (110-1900 A) cameras at 10 A resolution over an 8-hr period. The short-wavelength emission lines and continua of 2A0311-227 are f…
