Observations of Sunspot Oscillations in G band and Ca II H line with Solar Optical Telescope on Hinode
Kaori Nagashima, Takashi Sekii, Alexander G. Kosovichev +11
Exploiting high-resolution observations made by the Solar Optical Telescope onboard Hinode, we investigate the spatial distribution of power spectral density of oscillatory signal…

Kaori Nagashima, Hiroaki Isobe, Takaaki Yokoyama +3
On 2005 September 13 a filament eruption accompanied by a halo CME occurred in the most flare-productive active region NOAA 10808 in Solar Cycle 23. Using multi-wavelength observat…
Statistical Study of the Reconnection Rate in Solar Flares Observed with YOHKOH/SXT
Kaori Nagashima, Takaaki Yokoyama
We report a statistical study of flares observed with the Soft X-ray Telescope (SXT) onboard Yohkoh in the year of 2000. We measure physical parameters of 77 flares, such as the te…
