East Asian Observations of Low Latitude Aurora during the Carrington Magnetic Storm
Hisashi Hayakawa, Kiyomi Iwahashi, Harufumi Tamazawa +6
The magnetic storm around 1859 September 2, caused by so-called Carrington flare, was the most intense in the history of modern scientific observations, and hence is considered to…
"Unusual Rainbow and White Rainbow" A new auroral candidate in oriental historical sources
Hisashi Hayakawa, Hiroaki Isobe, Akito Davis Kawamura +3
Solar activity has been recorded as auroras or sunspots in various historical sources. These records are of much importance for investigating both long-term solar activities and ex…
Interplanetary particle transport simulation for warning system for aviation exposure to solar energetic particles
Yûki Kubo, Ryuho Kataoka, Tatsuhiko Sato
Solar energetic particles (SEPs) are one of the extreme space weather phenomena. A huge SEP event increases the radiation dose received by aircrews, who should be warned of such ev…
Saturation of Stellar Winds from Young Suns
Takeru K. Suzuki, Shinsuke Imada, Ryuho Kataoka +4
We investigate mass losses via stellar winds from sun-like main sequence stars with a wide range of activity levels. We perform forward-type magnetohydrodynamical numerical experim…
