Outline of Final Research Achievements

Various phenomena occurring at the solar surface can be observed by the ground telescopes and the satellites. Therefore they are a target of various hypotheses by astrophysics. We study it what kind of process does really work when high-energy particles are accelerated (solar cosmic rays) via by solar flares (the explosion of the solar surface). The origin of solar high-energy particles is deeply related to the origin of cosmic rays. We checked the acceleration process when ions and electrons were accelerated to a few GeV by analyzing the imaging data of soft X-rays, hard X-rays, high-energy gamma rays and ultraviolet rays. At that time we generally compared them with the solar neutron data acquired in the device of SEDA-FIB that was located on the International Space Station. The details are given in the attached pdf file.

Academic Significance and Societal Importance of the Research Achievements

太陽表面で爆発現象がたびたび発生する。この爆発は太陽フレアと呼ばれている。太陽フレアの際高エネルギーの放射線が地球に飛来する。このような高エネルギー放射線は物質を貫通するので、人体や電子機器に悪影響を及ぼす。そのため人類の宇宙開発にとっては無重力下での骨粗鬆症対策と共に重大な障壁となっている。いかに太陽からの高エネルギー放射線を避けるのか?この目的を果たすためには、まず太陽放射線がどのように作られるのかを知り、それを予知することが重要となる。本研究の成果は将来の月面探査や火星旅行のための必須の知識を得ることに役立っている。高エネルギー放射線は鉾でそれを防ぐための厚い障壁は盾である。
