Modeling of geocoronal solar wind charge exchange events detected with Suzaku
Daiki Ishi, Kumi Ishikawa, Yoshizumi Miyoshi +2
A model of geocoronal solar wind charge exchange (SWCX) emission was built and compared to five Suzaku detections of bright geocoronal SWCX events. An exospheric neutral hydrogen d…
Soft X-Ray Imaging of Magnetopause Reconnection Outflows Under Low Plasma- Solar Wind Conditions
Yosuke Matsumoto, Yoshizumi Miyoshi
We examined soft X-ray emission by the solar wind charge-exchange process around the Earth's magnetosphere using a global magnetohydrodynamic simulation model. The dayside magnetop…
Comparative study of electric currents and energetic particle fluxes in a solar flare and Earth magnetospheric substorm
Anton Artemyev, Ivan Zimovets, Ivan Sharykin +20
Magnetic field-line reconnection is a universal plasma process responsible for the conversion of magnetic field energy to the plasma heating and charged particle acceleration. Sola…
Suzaku observation of Jupiter's X-rays around solar maximum
Masaki Numazawa, Yuichiro Ezoe, Takaya Ohashi +6
We report on results of imaging and spectral studies of X-ray emission from Jupiter observed by Suzaku. In 2006 Suzaku had found diffuse X-ray emission in $1\unicode{x2013}5$ keV a…
Suzaku detection of enigmatic geocoronal solar wind charge exchange event associated with coronal mass ejection
Daiki Ishi, Kumi Ishikawa, Masaki Numazawa +5
Suzaku detected an enhancement of soft X-ray background associated with solar eruptions on 2013 April 14-15. The solar eruptions were accompanied by an M6.5 solar flare and a coron…
Enhancement of Terrestrial Diffuse X-ray Emission Associated With Coronal Mass Ejection and Geomagnetic Storm
Yuichiro Ezoe, Yoshizumi Miyoshi, Hiroshi Yoshitake +4
We present an analysis of a Suzaku observation taken during the geomagnetic storm of 2005 August 23-24. We found time variation of diffuse soft X-ray emission when a coronal mass e…
Coronal Electron Distribution in Solar Flares: Drift-Kinetic Model
Takashi Minoshima, Satoshi Masuda, Yoshizumi Miyoshi +1
Using a model of particle acceleration and transport in solar flares, we investigate the height distribution of coronal electrons by focusing on the energy-dependent pitch-angle sc…
Time Variability of the Geocoronal Solar Wind Charge Exchange in the Direction of the Celestial Equator
Yuichiro Ezoe, Ken Ebisawa, Noriko Y. Yamasaki +5
We report the detection of a time variable OVII line emission in a deep 100 ks Suzaku X-ray Imaging Spectrometer spectrum of the Galactic Ridge X-ray emission. The observed line in…
