Interplanetary Disturbances

DOI: 10.1007/978-3-540-31534-6_4 Bibcode: 2004LNP...656...71W

Wimmer-Schweingruber, Robert F.

The Sun emits the variable solar wind which interacts with the very local interstellar medium to form the heliosphere. Hence variations in solar activity strongly influence interplanetary space, from the Suns surface out to the edge of the heliosphere. Superimposed on the solar wind are mass ejections from the Sun and/or its corona which disturb t…

Mid-Infrared properties of Early-type galaxies

DOI: 10.1023/B:ASTR.0000014972.15891.9b Bibcode: 2004Ap&SS.289..415X

Madden, S. C.; Vigroux, L.; Xilouris, E. M.

We have conducted a survey of early-type galaxies using the ISOCAMinstrument on board the Infrared Space Observatory (ISO)in order to probe their dustcontent. We present Mid-Infrared photometric properties for a sampleof 20 galaxies observed at 4.5, 7 and 15 µ$m. Using diagnosticcolor-color diagrams, we can delineate the different Mid-Infrar…

Multiple Flux Rope Events at the High-Latitude Magnetopause: Cluster/Rapid Observation on January 26, 2001

Bibcode: 2004ChJG...47.2634H

Reme, H.; Cao, Jin-Bin; Daly, P. +15 more

From 11:10 to 11:40UT on January 26, 2001 the four Cluster II spacecraft were located in the duskside high latitude regions of the magnetosheath and magnetosheath boundary layer (MSBL). During this time Interval the interplanetary magnetic field (IMF) had a negative Bz component. A detailed study on the multiple flux ropes (MFRs) observed in this …

La Cometa 67P Churyumov-Gerasimenko el il contributo degli astrofili italiani alla missione ROSETTA

Bibcode: 2004AsUAI...4...54M

Milani, Giannantonio

Comet 67P Churyumov-Gerasimenko, the new target of the ROSETTA spacecraft, was oberved during the 2002/2003 apparition, displacing an unusual tail. The tail was compatible with a neck-line structure and this implies a high nuclear activity far before perihelion. Images and data from the current and previous apparitions show that the comet reaches …

Towards a fluid description of directional particle flux observations

DOI: 10.1016/j.astropartphys.2004.02.005 Bibcode: 2004APh....21..451P

Moussas, X.; Polygiannakis, J. M.; Alevizos, A.

We propose that, whenever directional flux measurements of a population of particles (e.g. solar energetic particles, cosmic rays, solar wind plasma) of well-defined energy resolution are available, new macroscopic fluid-like quantities (namely the energy dependent analog of density, mean velocity, anisotropic pressure, temperature and heat flux) …

Primary research on a complex solar radio burst and its characteristics of microwave sources

Bibcode: 2004PNAOC...1...56W

Wang, Min; Wang, Kun-Shan; Xie, Rui-Xiang +4 more

A very complex outstanding solar radio burst was observed with the wide-band spectrometer of NAOC on October 19, 2001. This burst was characterized by a broader band (decameter to decimeter) burst followed by a more intense narrow-band burst at the lower frequencies (decimetric). NoRH (Nobeyama Radio Heliograph) observations about this event at 17…

Nebular abundances in southern symbiotic stars

Bibcode: 2004BAAA...47..136L

Luna, G. J. M.; Costa, R. D. D.

We have calculated relative elemental abundances for a sample of 43 symbiotic stars. Helium abundances and the relative elemental abundances N/O, Ne/O were derived from new spectra collected in the optical range through low dispersion spectroscopy and from IUE low resolution spectra (SWP camera). The He ionic abundances were derived taking into ac…
