Dependence of the Characteristics of Solar Wind Discontinuities and Shocks with Heliolatitude and Radial Distance
Dickson Benjamin, A.; Prabhakaran Nayar, S. R.
The distribution of the shocks in the heliosphere and their characteristic variations are investigated using Ulysses observations. The jumps in solar wind velocity, IMF magnitude, and proton density across the shocks and discontinuities are evaluated and used to characterize them. The distribution of these discontinuities with respect to heliolati…
The peculiar horizontal branch morphology of the Galactic globular clusters NGC 6388 and NGC 6441.
Buss, G.
I present multiband optical and UV Hubble Space Telescope photometry of the two Galactic globular clusters NGC 6388 and NGC 6441, in order to investigate the nature of the physical mechanism(s) responsible for the existence of an extended blue tail and of a slope in the horizontal branch. Further evidence that the horizontal branch tilt cannot be …
Plasma Kinetics
Schwartz, Steven J.; Daly, Patrick W.; Lefebvre, Betrand
In Chapter 7 of ISSI SR-001, Schwartz et al. [1998] explain the basic ideas of analysis by means of plasma kinetics: Liouville mapping and finite gyroradius effects. Liouville mapping can be used to relate features of distribution functions such as heating, anisotropies or beams, to the field variations. It is based on the conservation of phase sp…
On analyses of satellite ion scale reconnection data
Mozer, F. S.; Cully, C. M.
Analyses of satellite-measured fields and flows through reconnecting current sheets have assumed that the relative velocity of the satellite and the current sheet is in the direction of the current sheet normal. During analyses, this relative normal velocity has been removed by translation of the satellite data. The assumption that the relative mo…
X-Ray and Optical Followup of Gamma-Ray (up to TeV) Sources
Masetti, N.
The imaging capabilities of the INTEGRAL and HESS observatories allow the study of hard X-ray and TeV sources with unprecedented positional accuracy. Here I review the multiwavelength followup studies which are currently being performed on the unidentified sources detected by these facilities in order to unveil their actual nature.
Active galaxies
Matt, G.
In this paper I will review, in an unavoidably incomplete and biased way, the main results obtained by XMM-Newton on Active Galactic Nuclei. I will then highlight the major issues still open in which XMM-Newton can still give important contributions, expecially if the observing programs will shift in the future towards more long exposures of singl…
Classifying the stellar environment around V838 Monocerotis
Schaefer, G. H.; Rosero-Rueda, V. A.; Bond, H. E. +2 more
The V838 Mon's behavior and the nature of the progenitor object are not well understood. Type B stars recently have been found in the vicinity of V838 Mon and it is thought that they may be part of a young open cluster. Since the cluster is in a spiral arm of the Galaxy, the identification of additional member stars is complicated; therefore, phot…
QSO number counts to B < 24.5 from hubble space telescope WFPC2 images
Anderson, Scott F.; Beck-Winchatz, Bernhard
We have conducted a survey for faint quasars to B < 24.5, z < 2.1 based on archival high-latitude Hubble Space Telescope Wide Field Planetary Camera 2 (WFPC2) images covering 0.04 deg2 of the sky in three filters spanning 2300 9600 Å. Taking advantage of the superb 0.1″ resolution of WFPC2, we have developed an approach to select …
Cross-identification of the hipparcos and 2MASS catalogs. Algorithm and programs
Zolotukhina, A. V.; Lazorenko, P. F.; Kharin, A. S.
A procedure for the cross-identification of the Hipparcos and 2MASS catalogs was developed. The algorithm and the cross-identification software are described.
