Research Abstract |
赤外線天文衛星「あかり」の中間赤外線全天サーベイの生データから画像を取り出し、さらにそこから点源の検出イベントを抽出するデータ解析パイプラインプログラムを開発た。このソフトウェアを全天のデータに対して実行して全天の画像データと点源の検出イベントを作成した。点源検出イベントからは、中間赤外での超過放射をもつ主系列の天体を抽出し、そのうちの一つに比較的温度が高く、中心星に近いところにあるデブリ円盤を持つことを示した。また白鳥座方向の中間赤外拡散放射マップから周囲に18ミクロンの拡散放射をもつ天体を抽出した。この天体は太陽系に近いところに位置する若い天体か、埋もれた大質量星か、あるいはまたシェルをもったAGB星であり、これまであまり着目されることのなかった天体にも中間赤外拡散放射をもとに興味深い天体が見つけ出せるということを示した。
