Abstract

This Project aims to obtain support for a visit of 26 days of the researcher Sebastien Hess (LATMOS- Laboratoire Atmosphères, Milieux, Observations Spatiales, França), in order to conduct scientific discussions, data analysis and interpretations of the results of the effects of solar wind on the Jupiter decametric (DAM) auroral radio emissions non-controlled by Io. The visiting researcher will have discussions with the researchers of the INPE's group Magnetosphere/Heliosphere (MAGHEL). This study will continue the joint works between the MAGHEL research group and the Observatory of Paris, which began during the previous FAPESP Jovem Pesquisador project, by the research who is responsible by the current project. The visiting researcher developed his PhD thesis in the Observatory of Paris, studying Jupiter DAM radio emissions and has expertise in this area. The soliciting researcher studied the solar wind effects on Jupiter DAM emission, using the Ulysses spacecraft, in cooperation with the Observatory of Paris research group. The visiting researcher is now in a new laboratory (LATMOS), but has cooperation with the Observatory of Paris group. The aim of this project is to study the Nançay radio telescope DAM emission catalog (available for 1995-2001), and the solar wind effect on the same, using the University of Michigan solar wind model (mSWiM). During the period of the visit, it is our goal to study the DAM emission characteristics (duration, average power and maximum frequency), and to identity the solar wind structures present near Jupiter orbit. We plan to start studies of correlation and interpretation of these results. The cooperation work shall continue after the visit, with results planned to be presented in talks in scientific conferences and published in scientific papers. (AU)
