Interstellar C IV and SI IV in the Direction of Loop I

DOI: 10.1007/BFb0104702 Bibcode: 1998LNP...506...99F

Freire Ferrero, R.

Nearby late-B and early-A stars show clear IS absorptions in Mg II, C II and other lines (IUE spectra). Some of them, in the Sco Cen direction, also show absorption features at C IV and Si IV line wavelengths. We discuss the possible formation of these lines in an intermediate temperature gas region between the dense and cold H I wall and the hot …

The turbulent state of cometary ion pickup generated fluctuations near comet P/Halley

DOI: 10.1029/97JA02667 Bibcode: 1998JGR...10312005K

Krauklis, I.; Johnstone, A. D.

One of the principal effects of an outgassing comet is to introduce additional mass into the solar wind flow. This mass-loading process results in the generation of Alfvén waves via ion-cyclotron resonance. In the case of the Halley encounter this source of ``new'' fluctuations was introduced into a low speed solar wind 0.89 AU from the sun. Previ…

Hst/uv Periodic Variations in the Intermediate Polar FO AQR

DOI: 10.1515/astro-1998-0212 Bibcode: 1998BaltA...7..293S

Mukai, K.; de Martino, D.; Buckley, D. A. H. +3 more

A preliminary analysis of high temporal HST UV spectroscopy, as well as SAAO BVRI photometry, has revealed that FO Aqr, differently from all previous observations, has changed from a spin dominated to an orbital dominated variability, both in lines and continuum. The spectral dependence of the orbital continuum, however, has not changed with time.…

ISOPHOT Observations of VEGA and Vega-like Stars

DOI: 10.1023/A:1001139624648 Bibcode: 1998Ap&SS.255..121H

Walker, H. J.; Heinrichsen, I.

Detailed ISOPHOT observations of the far infrared excess of α Lyrae (Vega) are presented. The data comprise photometry in the range 25µm to 200µm and high resolution 60µm scan data to compare with 60µm and 90µm oversampled maps. The dust disk around Vega is clearly resolved. In addition similar maps of HD98800, SAO226057, SAO186777 and α Piscis Au…

Acceleration in energetics ions (~1MeV) in corotating interaction regions

DOI: 10.1016/S0273-1177(97)00962-9 Bibcode: 1998AdSpR..21..555D

Balogh, A.; Forsyth, R. J.; Goldstein, B. E. +4 more

We have correlated the ~1 MeV proton intensity (J) measured at corotating reverse shocks detected by Ulysses near the ecliptic plane and in the southern hemisphere with the shock strength and shock normal angle. We find that J is essentially independent of the shock strength below 29 degS, whereas between 29 deg and 41 degS J showed a good correla…
