Research Abstract	本研究計画は、日米共同で製作され1993年2月に打ち上げられた「あすか」衛星の観測成果を最大限に挙げるために、国際協力のもとで観測計画、データの解析、集約、論文発表を遂行し、X線天文学発展に寄与することが目的である。この目的に沿って作業、解析を進め、本計画初年度の平成8年度には次の各項目に述べる実績、成果を挙げた。 (1)第4期公募で採択された約300天体の観測を平成8年12月に完了すると共に、第5期観測(平成9年1-12月を対象)の公募、審査を行い、平成8年12月の日米観測計画調整委員会で採択の最終決定を行った。現在この採択に基づいて第5期公募観測を始めている。 (2)X線望遠鏡および各測定装置の精密な較正を行うとともに、各検出器の応答関数の時間変化(蛍光比例計数管のゲインの変化、CCDカメラのエネルギー分解能の劣化)を明らかにし、これを「あすか」観測データ利用者に提供した。 (3)解析ソフトウエアーの拡充・改良、観測者占有権消失データのア-カイブデータ構築を米国NASA、宇宙研企画情報解析(PLAIN)センターと分担協力して進めた。「あすか」の1995年までの観測データについては、平成9年4月に一般研究者に公開することができるところまで準備が整った。 (4)活動的銀河核、超新星残骸、ブラックホール天体、遠方銀河団等の「あすか」による観測データの共同解析、結果の検討会、情報交流を行った。さらにこれら多数の得られた成果は各種学会・研究会において発表するとともに、学術専門誌に投稿された。平成8年度には「あすか」のデータに基づく論文約120篇は学術専門誌で出版されたが、このうち約半数の65篇は本研究参加者が主・共著者として関与したものである。また平成8年度には各大学から14名の大学院生が「あすか」の観測データにより博士論文を提出し、学位を取得した。 (5)「あすか」の打ち上げ3年経過を記念して文部省の国際シンポジウムが平成8年春に開催され、その科学的成果が総括された。本研究計画参加者はこの研究会で中心的な役割を果たしたが、その収録は平成9年1月に発行された。
