The large-scale magnetospheric electric field observed by Double Star TC-1
Rème, H.; Carr, C.; Liu, Z. X. +4 more
The relationship between the average structure of the inner magnetospheric large-scale electric field and geomagnetic activity levels has been investigated by Double Star TC-1 data for radial distances ρ between 4.5 RE and 12.5 RE and MLT between 18:00 h and 06:00 h from July to October in 2004 and 2005. The sunward component…

Spectroscopic analysis of the candidate β Cephei star σ Cas: Atmospheric characterization and line-profile variability
Catanzaro, G.; Ventura, R.; Ferrara, F. +1 more
This study is an exploratory search to ascertain for the first time the detailed properties of σ Cas as a candidate pulsator of β Cephei type in view of future observing campaigns. This search is devoted to a precise characterization of the parameters of the star for verifying its location with respect to the β Cephei instability region and to a p…
Coronal Radio Sounding Experiments with Mars Express: Scintillation Spectra during Low Solar Activity
Pätzold, M.; Bird, M. K.; Tellmann, S. +5 more
Coronal radio sounding observations were carried out with the radio science experiment MaRS on the ESA spacecraft Mars Express during the period from 25 August to 22 October 2004. Differential frequency and log-amplitude fluctuations of the dual-frequency signals were recorded during a period of low solar activity. The data are applicable to low h…
High-Latitude Inner Solar Wind from Pulsar Radio Sounding Observations
Smirnova, T. V.; Chashei, I. V.; Shishov, V. I.
Radio sounding experiments probing the inner solar wind by polarized pulses of pulsars PSR B0525+21 (J0528+22) and PSR B531+21 (J0534+22) were carried out in June 2005 and June 2007 on the large phased array of the Lebedev Physical Institute at 111 MHz in the period near the minimum of the solar-activity cycle. The lines of sight toward these puls…
Evolution and Energization of Energetic Electrons in the Inner Magnetosphere
Fennell, J. F.; Roeder, J. L.
In this paper we present a review of what we know about the evolution and energization of energetic electrons in the inner magnetosphere. We emphasize what we have learned since the review by Friedel et al. [17] that discussed in detail the possible acceleration mechanisms for these electrons. The primary result has been a greater focus on local a…
Double Star: Mission, Instruments and Joint Observations
Escoubet, C. P.; Fazakerley, A. N.; Dunlop, M. W. +5 more
The Chinese National Space Agency (CNSA) Double Star (DSP) spacecraft, TC-1 and TC-2 were launched in December 2003 and July 2004 into near equatorial and polar orbits respectively. During more than 3 years of operations they have maintained a close phasing with the ESA four-spacecraft mission to produce the first, well coordinated multi-scale mea…
Organic Compounds Analysis by TOF-SIMS in the Frame of Rosetta/COSIMA Space Mission
Hilchenbach, M.; Briois, C.; Cottin, H. +4 more
Comets are remainders of the Solar System formation. They also have been discussed as possible sources of water (Deloule 1998) and molecules relevant in the chemical evolution leading to the emergence of life on Earth (Oro 1961). Thus, cometary grains are interesting objects for planetological and astrobiological studies: their analysis can give u…
New Suspected Variable (NSV) Stars in the Galactic Open Cluster NGC 2264. Periodic Variables: A CoRoT View
Greaves, J.
A recent release of CoRoT mission exoplanet fields' data included those for stars likely connected with the Galactic open cluster NGC 2264 that are also included in the New Suspected Variables' Catalogue, NSV (Kukarkin et al. 1982), and its Supplement (Kazarovets et al. 1998). Using the VizieR B/COROT version these data were crossmatched with the …
Large Scale structure of the local Universe traced by hard X-ray emitting AGNs
Krivonos, Roman; Revnivtsev, Mikhail
We detected a spatial anisotropy in the distribution of the nearby hard X-ray emitting AGNs and showed that it well correlates with known nearby anisotropies of the matter density distribution. Using the AGN sample from the INTEGRAL all sky survey we for the first time directly showed that the density fluctuations of the matter in the local Univer…
