Outline of Research at the Start

中性子星と普通の星が連星系を組むと、星から放出されたガスが中性子星に落下し、その莫大な重力エネルギーを解放することでX線で極めて明るく輝く。中性子星は1兆ガウスという地上では到底実現できない強い磁場を持っており、そのような極限環境でガスが降着する過程は依然として物理的な理解が得られていない。本研究は、X線偏光観測とモンテカルロ放射計算という実験・理論の両面で新しい手法を開発して、この非常に複雑なシステムの物理的理解を目指す。

Outline of Final Research Achievements

We have studied gas accretion onto strongly magnetized neutron stars from the aspects of instrumentation and observational data analysis. We have developed a new compact hard X-ray imaging polarimeter using the combination of a fine-pixel CMOS imaging sensor and a coded mask. We have also found that the time variability of the disk-fed accreting pulsar Cen X-3 is caused by the stellar wind and have obtained spectral variability by the observer’s direction.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した撮像偏光計は、半導体検出器を光電吸収型偏光計として用いるという全く新しいものである。微細加工符号化開口マスクと組み合わせることで、非常に小さな撮像偏光計システムを構築することができ、将来の宇宙科学ミッションへの適用も期待できる。Cen X-3のデータ解析はNuSTAR衛星の高い統計量データを活かして、これまで曖昧だった天体の時間変動の議論を決着させ、降着流の物理モデルを構築するための重要な基礎になる。
