M-dwarf's Chromosphere, Corona and Wind Connection via the Nonlinear Alfvén Wave
Takahito Sakaue, Kazunari Shibata
M dwarf's atmosphere is expected to be highly magnetized. The magnetic energy can be responsible for heating the stellar chromosphere and corona, and driving the stellar wind. The…
Small-scale Turbulent Motion of the Plasma in a Solar Filament as the Precursor of Eruption
Daikichi Seki, Kenichi Otsuji, Hiroaki Isobe +5
A filament, a dense cool plasma supported by the magnetic fields in the solar corona, often becomes unstable and erupts. It is empirically known that the filament often demonstrate…
Nonlinear Alfvén Wave Model of Stellar Coronae and Winds from the Sun to M dwarfs
Takahito Sakaue, Kazunari Shibata
M dwarf's atmosphere and wind is expected to be highly magnetized. The nonlinear propagation of Alfvén wave could play a key role in both heating the stellar atmosphere and driving…
Energy Transfer by Nonlinear Alfvén Waves in the Solar Chromosphere, and Its Effect on Spicule Dynamics, Coronal Heating, and Solar Wind Acceleration
Takahito Sakaue, Kazunari Shibata
Alfvén waves are responsible for the transfer of magnetic energy in the magnetized plasma. They are involved in heating solar atmosphere and driving solar wind through various nonl…
Dynamic Processes of the Moreton Wave on 2014 March 29
Denis P. Cabezas, Ayumi Asai, Kiyoshi Ichimoto +4
On 2014 March 29, an intense solar flare classified as X1.0 occurred in the active region 12017. Several associated phenomena accompanied this event, among them a fast-filament eru…
Statistical Study of Solar White-light Flares and Comparison with Superflares on Solar-type Stars
Kosuke Namekata, Takahito Sakaue, Kyoko Watanabe +9
Recently, many superflares on solar-type stars were discovered as white-light flares (WLFs). A correlation between the energies (E) and durations (t) of superflares is derived as $…
