ENA diagnostics of auroral activity at Mars
Ip, W. -H.
One prominent feature of solar wind - Mars interaction has to do with the presence of strong crustal magnetic fields, especially, in the southern hemisphere. This physical property has set Mars apart from Venus as far as the kinetic effect in detail. In this paper, we review briefly the recent particles-and-fields measurements at Mars in connectio…
Search for satellites near (21) Lutetia using OSIRIS/Rosetta images
Jorda, L.; Lara, L. M.; Bertaux, J. -L. +42 more
On 2010 July 10 the ESA Rosetta mission flew by the large asteroid (21) Lutetia. One of the scientific goals of the onboard OSIRIS instrument was the search for satellites of the asteroid, with more than 20 images specifically dedicated to this topic. An observational campaign was devised with a selection of filters and exposure times tailored to …
Rosetta rendezvous and CONSERT operations in 2014: A chimeric surface model of 67P/Churyumov Gerasimenko
Kofman, Wlodek; Herique, Alain; Rogez, Yves +2 more
In 2014 the European Space Agency's Rosetta probe will rendezvous with the comet 67P/Churyumov Gerasimenko (67P) and the Philae Lander will land on the surface of the nucleus. Following the landing, the COmet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) radar will perform the tomography of the nucleus by measuring radiowave prop…
Brightness and polarization opposition effects at low phase angles of the Saturnian satellites Tethys, Dione, and Rhea
Kulyk, Irina
The photometric and polarization phase dependences of the Saturnian moons Tethys, Dione, and Rhea are studied in a narrow domain of solar phase angles around opposition by using observations obtained with the 2-m RCC telescope of the National Astronomical Observatory at Rozhen, Bulgaria. The observations were made in the solar phase angle range fr…
Titan through time: Formation, evolution and fate

A despeckle filter for the Cassini synthetic aperture radar images of Titan's surface
Coustenis, Athena; Solomonidou, Anezina; Bampasidis, Georgios +1 more
Cassini synthetic aperture radar (SAR) images of Titan, the largest satellite of Saturn, reveal surface features with shapes ranging from quasi-circular to more complex ones, interpreted as liquid hydrocarbon deposits assembled in the form of lakes or seas. One of the major problems hampering the derivation of meaningful texture information from S…
The large-scale energetic ion layer in the high latitude Jovian magnetosphere as revealed by ULYSSES/HI-SCALE cross-field intensity-gradient measurements
Sarris, E. T.; Anagnostopoulos, G. C.; Karanikola, I. +1 more
ULYSSES investigated the high latitude Jovian magnetosphere for a second time, after Pioneer 11 mission, and gave us the opportunity to search the structure and the dynamics of this giant magnetosphere above the magnetodisc. Kivelson and Williams (1976) and Kennel and Coroniti (1979) reported that Pioneer 11 observed energetic particle intensities…
Wave mechanism of the magnetospheric convection
Leonovich, A. S.
The problem of momentum transfer from the solar wind to the geotail via magnetosonic waves has been solved. The structure of the wave field of monochromatic MHD oscillations is calculated in a cylindrical model of the geotail with a background plasma distribution typical of the geotail lobes. Fast magnetosonic waves entering the magnetosphere from…
On the possibility to determine the electrical conductivity of 67P/CG from ROSETTA magnetic field observations
Glassmeier, K. -H.; Carr, C.; Richter, I. +3 more
The ROSETTA mission to comet 67P/Churyumov-Gerasimenko presents us for the first time the opportunity to study the interior of a cometary nucleus. Information about the electrical conductivity and its distribution inside the nucleus can be derived by measuring the magnetic fields induced in the nucleus by variations of the interplanetary magnetic …
On the spatial character of the ∼10 h electron spectrum modulation in the Jovian magnetosphere
Anagnostopoulos, G. C.; Karanikola, I.
On its voyage in the south duskside Jovian magnetosphere, after leaving the plasma sheet, Ulysses entered a large scale high latitude layer of energetic ions and electrons, extending from ∼49 RJ to ∼83 RJ. Ulysses traveled within this region from the end of day 41 until the first magnetopause crossing, early on day 43, 1992 a…
