Latitudinal extent of large-scale structures in the solar wind
McComas, D. J.; Riley, P.; Elliott, H. A.
Comparison of solar wind observations from the ACE spacecraft, in the ecliptic plane at ~ 1 AU, and the Ulysses spacecraft as it orbits over the Sun's poles, provides valuable information about the latitudinal extent and variation of solar wind structures in the heliosphere. While qualitative comparisons can be made using average properties observ…
XESS: An XMM Extended Source Survey

Interstellar Silicon Abundance
Gnacinski, P.
We present 34 measurements of silicon gas phase column densities in the interstellar medium. We have used spectra containing the SiII 1808 Ang line which were obtained with the Goddard High Resolution Spectrograph (GHRS) aboard the Hubble Space Telescope (HST). Extinction curve parameters are determined for analyzed lines of sight and relation bet…
First IBIS results on the high energy emission of Cygnus X-2
Santangelo, A.; Capitanio, F.; Ubertini, P. +4 more
The bright low-mass X-ray binary Cyg X-2 was in the field of view of the IBIS telescope during the early Cygnus region observations, executed during the INTEGRAL Performance Verification Phase. The data presented are spanning about one week and cover the rising edge of one of the two peaks of the ~82 day cycle of the Cyg X-2 light curve. The IBIS …
Multipolar Bubbles, Point-Symmetry, and Jets in Dying Stars
Sahai, R.; Morris, M. R.
The imaging of young planetary and pre-planetary nebulae (YPNe and PPNe) with unprecedented high angular resolution and dynamic range using the Hubble Space Telescope (HST), has shown that most of these objects are highly aspherical, with complex multipolar morphologies. The complexity, organization and symmetry of the morphological structures has…
The mean stellar parameters from IUE and hipparcos data

6C radio galaxies at z∼1: the influence of radio power on the alignment effect
Best, Philip N.; Inskip, Katherine J.; Longair, Malcolm S.
Powerful radio galaxies often display enhanced optical/UV continuum emission and extended emission line regions, elongated and aligned with the radio jet axis. The expansion of the radio source strongly affects the gas clouds in the surrounding IGM, and the kinematic and ionization properties of the extended emission line regions display considera…
Erratum: The ISO-SWS spectrum of planetary nebula NGC 7027
Pottasch, S. R.; Beintema, D. A.; Bernard-Salas, J. +1 more
Based on observations with ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries: France, Germany, The Netherlands and UK) and with the participation of ISAS and NASA.
Fine structure of the polar cusp as deduced from the plasma wave and plasma measurements
Sauvaud, J. -A.; Santolik, O.; Parrot, M. +7 more
Plasma waves are one of the most significant features of plasma. They are a very sensitive indicator of the boundaries and inner structure of different regions in space plasmas. The data gathered onboard Interball 1 and Magion 4 in the polar cusp indicate that plasma wave intensity changes very rapidly with a characteristic period of the order of …
