Conditions for Solar Prominence Formation Triggered by Single Localized Heating
Takero Yoshihisa, Takaaki Yokoyama, Takafumi Kaneko
We performed numerical simulations to study mechanisms of solar prominence formation triggered by a single heating event. In the widely accepted ``chromospheric-evaporation condens…
Impact of subsurface convective flows on the formation of sunspot magnetic field and energy build-up
Takafumi Kaneko, Hideyuki Hotta, Shin Toriumi +1
Strong solar flares occur in -spots characterized by the opposite-polarity magnetic fluxes in a single penumbra. Sunspot formation via flux emergence from the convection zone to…
Data-driven MHD simulation of successive solar plasma eruptions
Takafumi Kaneko, Sung-Hong Park, Kanya Kusano
Solar flares and plasma eruptions are sudden releases of magnetic energy stored in the plasma atmosphere. To understand the physical mechanisms governing their occurrences, three-d…
Impact of Dynamic State on the Mass Condensation Rate of Solar Prominences
Takafumi Kaneko, Takaaki Yokoyama
The interiors of quiescent prominences are filled with turbulent flows. The evolution of upflow plumes, descending pillars, and vortex motions has been clearly detected in high-res…
Reconnection-Condensation Model for Solar Prominence Formation
Takafumi Kaneko, Takaaki Yokoyama
We propose a reconnection-condensation model in which topological change in a coronal magnetic field via reconnection triggers radiative condensation, thereby resulting in prominen…
Apparent cross-field superslow propagation of magnetohydrodynamic waves in solar plasmas
T. Kaneko, M. Goossens, R. Soler +4
In this paper we show that the phase mixing of continuum Alfvén waves and/or continuum slow waves in magnetic structures of the solar atmosphere as, e.g., coronal arcades, can crea…
Numerical Study on In-Situ Prominence Formation by Radiative Condensation in the Solar Corona
Takafumi Kaneko, Takaaki Yokoyama
We propose an in-situ formation model for inverse-polarity solar prominence and demonstrate it using self-consistent 2.5-dimensional magnetohydrodynamics simulations, including the…
Simulation Study of Solar Plasma Eruptions Caused by Interactions between Emerging Flux and Coronal Arcade Fields
T. Kaneko, T. Yokoyama
We investigate the triggering mechanisms of plasma eruptions in the solar atmosphere due to interactions between emerging flux and coronal arcade fields by using two-dimensional MH…
