Quasi-periodic oscillations in flares and coronal mass ejections associated with magnetic reconnection
Takuya Takahashi, Jiong Qiu, Kazunari Shibata
We propose a mechanism for quasi-periodic oscillations of both coronal mass ejections (CMEs) and flare loops as related to magnetic reconnection in eruptive solar flares. We perfor…
Sheath-Accumulating Propagation of Interplanetary Coronal Mass Ejection
Takuya Takahashi, Kazunari Shibata
Fast interplanetary coronal mass ejections (interplanetary CMEs, or ICMEs) are the drivers of strongest space weather storms such as solar energetic particle events and geomagnetic…
Shock-Cloud Interaction in the Solar Corona
Takuya Takahashi
Flare associated coronal shock waves sometimes interact with solar prominences leading to large amplitude prominence oscillations. Such prominence activation gives us unique opport…
Scaling Relations in Coronal Mass Ejections and Energetic Proton Events associated with Solar Superflares
Takuya Takahashi, Yoshiyuki Mizuno, Kazunari Shibata
In order to discuss the potential impact of solar 'superflares' on space weather, we investigated statistical relations among energetic proton peak flux with energy higher than $ 1…
Prominence Activation by Coronal Fast Mode Shock
Takuya Takahashi, Ayumi Asai, Kazunari Shibata
An X5.4 class flare occurred in active region (AR) NOAA11429 on 2012 March 7. The flare was associated with very fast coronal mass ejection (CME) with its velocity of over 2500 km/…
Coronal magnetic field and the plasma beta determined from radio and multiple satellite observations
Kazumasa Iwai, Kiyoto Shibasaki, Satoshi Nozawa +5
We derived the coronal magnetic field, plasma density, and temperature from the observation of polarization and intensity of radio thermal free-free emission using the Nobeyama Rad…
