[PEM08-P21] Soft-X ray emissions from Geospace: Possible science objectives of GEO-X
キーワード：太陽風磁気圏相互作用、軟X線放射
Recent studies have indicated that charge-exchange between geocorona and
On+ ions of the solar wind causes the soft-X ray emission. The soft-X ray
emission can be used as a tool to measure global topology of Geospace.
In order to investigate how we can observe the soft-X ray emissions, we conduct
a computer simulation by a code coupling of the global magnetospheric MHD
simulation model (Matsumoto+, 2010) and empirical geocorona model. The
simulation shows clear emissions from the dayside sheath region as well as the cusp region.
The new satellite project GEO-X has been proposed to measure the
soft-X ray emission through solar wind charge exchange (SWCX) from the
dayside magnetosphere. In this presentation, we show the possible
soft-X ray images by the computer simulation, by considering the GEO-X
satellite orbit.
