Magnetohydrodynamic simulation of coronal mass ejections using interplanetary scintillation data observed from radio sites ISEE and LOFAR

Kazumasa Iwai, Richard A. Fallows, Mario M. Bisi +4

Interplanetary scintillation (IPS) is a useful tool for detecting coronal mass ejections (CMEs) throughout interplanetary space. Global magnetohydrodynamic (MHD) simulations of the…

Testing the Alfvén-wave model of the solar wind with interplanetary scintillation

Munehito Shoda, Kazumasa Iwai, Daikou Shiota

Understanding the mechanism(s) of the solar wind acceleration is important in astrophysics and geophysics. A promising model of the solar wind acceleration is known as the wave/tur…

Validation of Coronal Mass Ejection Arrival-Time Forecasts by Magnetohydrodynamic Simulations based on Interplanetary Scintillation Observations

Kazumasa Iwai, Daikou Shiota, Munetoshi Tokumaru +3

Coronal mass ejections (CMEs) cause various disturbances of the space environment; therefore, forecasting their arrival time is very important. However, forecasting accuracy is hin…

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…

Development of a coronal mass ejection arrival time forecasting system using interplanetary scintillation observations

Kazumasa Iwai, Daikou Shiota, Munetoshi Tokumaru +3

Coronal mass ejections (CMEs) cause disturbances in the environment of the Earth when they arrive at the Earth. However, the prediction of the arrival of CMEs still remains a chall…

Magnetohydrodynamic Modeling of a Solar Eruption Associated with X9.3 Flare Observed in Active Region 12673

Satoshi Inoue, Daikou Shiota, Yumi Bamba +1

On SOL2017-09-06 solar active region 12673 produced an X9.3 flare which is regarded as largest to occur in solar cycle 24. In this work we have preformed a magnetohydrodynamic (MHD…
