Magnetic Tornado Properties: A Substantial Contribution to the Solar Coronal Heating via Efficient Energy Transfer
Hidetaka Kuniyoshi, Munehito Shoda, Haruhisa Iijima +1
In solving the solar coronal heating problem, it is crucial to comprehend the mechanisms by which energy is conveyed from the photosphere to the corona. Recently, magnetic tornadoe…
Mean-field analysis on large-scale magnetic fields at high Reynolds numbers
Ryota Shimada, Hideyuki Hotta, Takaaki Yokoyama
Solar magnetic fields comprise an 11-year activity cycle, represented by the number of sunspots. The maintenance of such a solar magnetic field can be attributed to fluid motion in…
Fast magnetic wave could heat the solar low-beta chromosphere
Yikang Wang, Takaaki Yokoyama, Haruhisa Iijima
Magnetohydrodynamic (MHD) waves are candidates for heating the solar chromosphere, although it is still unclear which mode of the wave is dominant in heating. We perform two-dimens…
Simulation of Alfven wave propagation in magnetic chromosphere with radiative loss: effects of non-linear mode coupling on chromospheric heating
Yikang Wang, Takaaki Yokoyama
We perform magnetohydrodynamic (MHD) simulations to investigate the propagation of Alfven wave in magnetic chromosphere. We use the 1.5-dimensional expanding flux tube geometry set…
Inverse FIP Effects in Giant Solar Flares Found from Earth X-Ray Albedo with Suzaku/XIS
Satoru Katsuda, Masanori Ohno, Koji Mori +21
We report X-ray spectroscopic results for four giant solar flares occurred on 2005 September 7 (X17.0), 2005 September 8 (X5.4), 2005 September 9 (X6.2), and 2006 December 5 (X9.0)…
Estimating the temperature and density of a spicule from 100 GHz data obtained with ALMA
Masumi Shimojo, Tomoko Kawate, Takenori J. Okamoto +6
We succeeded in observing two large spicules simultaneously with the Atacama Large Millimeter/submillimeter Array (ALMA), the Interface Region Imaging Spectrograph (IRIS), and the…
