On-line access to the heliospheric measurements at high latitudes using the ESA archive for ULYSSES data

Sanderson, T. R.; Marsden, R. G.; Tranquille, C.

Ulysses is currently making its second orbit of the Sun, having successfully provided unique and continuous measurements of heliospheric particles and fields as a function of heliographic latitude during its first passes of the solar polar regions. The new measurements will give an insight into the dynamics of the heliosphere at solar maximum, in …

Gradients and flows in Jupiter's magnetosphere determined from the anisotropies of ~1 MeV protons

Balogh, A.; Forsyth, R. J.; Dunlop, M. W. +4 more

For near-isotropic distributions of energetic ions, the field-perpendicular first order anisotropies which occur are due both to plasma flows transverse to B, and to field-perpendicular spatial gradients in the ion flux. A technique has been developed to separate these by examining the variation of the anisotropy with ion energy. This has been app…

The discovery of 8.7 S pulsations from the ultrasoft X-ray source 4U0142+61

Mereghetti, S.; Stella, L.; Israel, G. L.

We discovered a periodicity at ~8.7 s from the X-ray sources 4U0142+61, previously considered a possible black hole candidate on the basis of its ultrasoft spectrum. The pulsations are visible only in the 1-4 keV energy range, during an observation obtained with the EXOSAT satellite in August 1984. In the same data, periodic oscillations at 25 min…

Towards a Multi-Dimensional Stellar Classification System

Stock, J.; Agostinho, R.; Rose, J. A. +2 more

Practically all the MK spectral types known today are the result of visual inspection of photographic spectra. This includes the monumental work by Nancy Houk. Two questions related to the MK system remained unanswered all along, namely 1) How accurate are the luminosities and intrinsic colors derived from these types? And 2) Can the classificatio…

The Sun and its role in the heliosphere. Proceedings. E2.2 Symposium of COSPAR Scientific Commission E held during the Thirty-first COSPAR Scientific Assembly, Birmingham (UK), 14 - 21 Jul 1996.

Antonucci, E.; Page, D. E.

The following topics were dealt with: solar corona, solar wind, structure, composition and variations, solar wind plasma, Ulysses measurements, heliospheric magnetic fields, interplanetary medium, interplanetary plasma and shocks, and energetic particle fluxes.

The Tokyo PMC Catalog 90 - 93: catalog of positions of 6649 stars observed in 1990 through 1993 with Tokyo Photoelectric Meridian Circle.

Yoshizawa, Masanori; Suzuki, Shunsaku

The sixth annual catalog of the Toyko PMC is presented for 6649 stars, which were observed at least two times in January 1990 through March 1993. The mean positions of the stars observed in the above period are given in the catalog at the corresponding mean epochs of observations of individual stars. The coordinates of the catalog are based on the…
